Definitions
- the present invention relates to implantable prosthetic valves. More particularly, the invention relates to a valve prosthesis for cardiac implantation or for implantation in other body ducts where the prosthesis has improved flow characteristics.
- a highly desirable, and often preferred design utilizes a cylindrical stent platform of either balloon expandable or self-expanding metal designs. Usually these stents follow the cellular designs which tend to have higher radial strength and less foreshortening than wire-wound platforms.
- Such cylindrical stents offer a stable and reproducible expansion platform for attaching valves and may be manufactured from a variety of biocompatible metals including stainless steels, titanium alloys, platinum-iridium, nickel-titanium alloys, chromium alloys, or tantalum.
- the retrograde flow characteristics are most important in low flow/low pressure systems where the valve leaflets may thrombose in the presence of poor retrograde laminar flow.
- Stented valves are passive devices. The valves function as a result of changes in pressure and flow.
- An aortic stented valve opens passively when the pressure in the left ventricle exceeds the pressure in the aorta (plus any resistance required to open the valve). The valve closes when the pressure in the left ventricle is less than the pressure in the aorta.
- the flow characteristics are critical to effect the closing of the aortic valve, otherwise regurgitation will ensue.
- Laminar flow is the normal condition found in most of the circulatory system. It is characterized by concentric layers of blood moving in parallel down the length of the blood vessel. The highest velocity is found in the middle of the blood vessel while the lowest is found along the wall. The flow is parabolic in a long straight vessel under steady flow conditions.
- Non-laminar, or turbulent, flow is useful to the circulatory system.
- the aortic valve opens into the sinus of Valsalva at the inferior aspect of the ascending aorta.
- This sinus has two key functions: First, it maximizes the flow characteristics so that the aortic valve closes during diastole. And second, it optimizes coronary sinus flow and perfusion.
- Laminar flow makes the retrograde flow characteristics of valves mounted in cylindrical stents problematic as the flow along the wall is least, which is central to the closing of a valve. Such laminar flow with its attendant drawbacks is a characteristic of known stented valves. There is a need to have stented valves where the retrograde flow characteristics will be non-laminar, which will be advantageous with regard to valve closing.

- a main aspect of the present invention is the introduction of several novel designs for an implantable prosthetic valve. Another aspect of the present invention is the disclosure of several manufacturing methods for implantable prosthetic valves in accordance with the present invention. A further aspect of the present invention is the provision of novel deployment and positioning techniques suitable for the valve of the present invention.
- the implantable prosthetic valve of the present invention comprises a leaflet-valve assembly, preferably tricuspid but not limited to tricuspid valves only, consisting of a conduit having an inlet end and an outlet, made of pliant material arranged so as to present collapsible walls at the outlet.
- the valve assembly is mounted on a support structure or frame such as a stent adapted to be positioned at a target location within the body duct and deploy the valve assembly by the use of deploying means, such as a balloon catheter or similar devices.
- the annular frame is able to be posed in two positions, a crimped position where the conduit passage cross-section presented is small so as to permit advancing the device towards its target location, and a deployed position where the frame is radial extended by forces exerted from within (by deploying means) so as to provide support against the body duct wall, secure the valve in position and open itself so as to allow flow through the conduit.

- the support stent is preferably annular, but may be provided in other shapes too, depending on the cross-section shape of the desired target location passage.
- Manufacturing of the implantable prosthetic valve of the present invention can be done in various methods, by using pericardium or, for example, by using artificial materials made by dipping, injection, electrospinning, rotation, ironing, or pressing.
- the attachment of the valve assembly to the support stent can be accomplished in several ways, such as by sewing it to several anchoring points on the support frame or stent, or riveting it, pinning it, adhering it, or welding it, to provide a valve assembly that is cast or molded over the support frame or stent, or use any other suitable way of attachment.
- floating supports may be added to enhance the stability of the device and prevent it from turning inside out.
- An important aspect of certain embodiments of the present invention is the provision of rigid support beams incorporated with the support stent that retains its longitudinal dimension while the entire support stent may be longitudinally or laterally extended.
- FIGS. 1 and 2 illustrate a general tricuspid implantable prosthetic valve 10 in accordance with a preferred embodiment of the present invention, suitable for percutaneous deployment using an expandable stent or similar deploying means, shown in its deployed position.
- Valve 10 comprises a valve assembly 20 having an inlet 22 and an outlet 24 , the outlet walls consisting of collapsible pliant leaflet material 26 that is arranged to collapse in a tricuspid arrangement.
- Valve assembly 20 is attached to an annular support stent 32 , the one in this figure being a net-like frame designed to be adapted to crimp evenly so as to present a narrow configuration and be radially deployable so as to extend to occupy the passage at the target location for implantation in a body duct.
- Support beams 34 are provided on annular support stent 32 to provide anchorage to valve assembly 20 .
- Support beams 34 are optionally provided with bores 36 to allow stitching of valve assembly 20 to support beams 34 by thread, wire, or other attachment means.
- the proximal portion 38 of support stent 32 is snuggly fit or fastened to the proximal portion of valve assembly 20 so that any flow is only into inlet 22 .
- the radial sections of each leaflet 26 is closed by stitching, gluing or other means to narrow outlet 24 .
- the distal portion 42 of support stent 32 is narrower than proximal portion 38 . The combination of the effect on flow characteristics due to the narrowing of support stent 32 and the narrowing of outlet 24 is sufficient to engender the desired effect or flow characteristics, namely, non-laminar retrograde flow that will assist in the closing of leaflets 26 .
- a prosthetic valve 50 comprises a valve assembly 52 positioned within a support stent 54 .
- the proximal 56 and distal 58 portions of support stent 54 are narrow as compared to the mid-portion 60 of support stent 54 , where valve assembly 52 is positioned.
- valve assembly 52 is preferably positioned co-axially and at a small distance, for example, from 0.5 to 3 cm, from the interior surface 64 of support stent 54 .
- Valve assembly 52 is attached by connecting membrane 66 to stent supports 68 , which optimally have holes or projections 70 to anchor said membranes 66 . Any annular space between interior surface 64 and valve assembly 54 is filled with appropriate material to prevent flow around valve assembly 54 .
- Valve leaflets are shown in closed 72 and open 74 positions.
- Valve assembly 54 is shown in a closed position wherein leaflets 70 inhibit flow.
- valve assembly 54 will preferably be from about 40 to 80% of the cross-sectional area across support stent midsection 60 .
- the preferred embodiments representing an implantable prosthetic valve in accordance with the present invention are relatively easy to manufacture as they are generally flat throughout most of the production process and only at the final stage of mounting the other elements of the valve assembly on the support frame, a three dimensional form is established.
- a typical size of an aortic prosthetic valve is from about 19 to about 26 mm in diameter.
- a maximal size of a catheter inserted into the femoral artery should be no more than 9 mm in diameter.
- the present invention introduces a device, which has the ability to change its diameter from about 4 mm to about 26 mm.
- Artificial valves are not new; however, artificial valves in accordance with the present invention posses the ability to change shape and size for the purpose of delivery and as such are novel. These newly designed valves require new manufacturing methods and technical inventions and improvements, some of which were described herein.
- the material of which the valve is made from can be either biological or artificial. In any case new technologies are needed to create such a valve.
- the blood vessels determine the size during delivery, and the requirements for it to work efficiently, there is a need to mount it on a collapsible construction which can be crimped to a small size, be expanded to a larger size, and be strong enough to act as a support for the valve function.
- This construction which is in somewhat similar to a large “stent”, can be made of different materials such as Nitinol, biocompatible stainless steel, polymeric material or a combination of all. Special requirement for the stent are a subject of some of the embodiments discussed herein.
- Another major aspect of the design of the valve of the present invention is the attachment to the body.

Abstract
Description
- The present invention relates to implantable prosthetic valves. More particularly, the invention relates to a valve prosthesis for cardiac implantation or for implantation in other body ducts where the prosthesis has improved flow characteristics.
- Several prosthetic valves are known. See, for example, U.S. Pat. No. 5,411,552 (Andersen et al.), entitled VALVE PROSTHESIS FOR IMPLANTATION IN THE BODY AND CATHETER FOR IMPLANTING SUCH VALVE PROSTHESIS, which discloses a valve prosthesis comprising a stent made from an expandable cylinder-shaped thread structure comprising several spaced apices. See, also, U.S. Pat. No. 6,168,614 (Andersen et al.), entitled VALVE PROSTHESIS FOR IMPLANTATION IN THE BODY, U.S. Pat. No. 5,840,081 (Andersen et al.), entitled SYSTEM AND METHOD FOR IMPLANTING CARDIAC VALVES, and PCT Application No. PCT/EP97/07337 (Letac, Cribier et al.), published as WO 98/29057, entitled VALVE. PROSTHESIS FOR IMPLANTATION IN BODY CHANNELS, all of which are incorporated herein by reference.
- In the development of stented valves, a highly desirable, and often preferred design utilizes a cylindrical stent platform of either balloon expandable or self-expanding metal designs. Usually these stents follow the cellular designs which tend to have higher radial strength and less foreshortening than wire-wound platforms.
- Such cylindrical stents offer a stable and reproducible expansion platform for attaching valves and may be manufactured from a variety of biocompatible metals including stainless steels, titanium alloys, platinum-iridium, nickel-titanium alloys, chromium alloys, or tantalum.
- Polymeric, bovine venous, pericardial, and porcine valve constructs have lead the early development efforts of stent-valve designs. All of the early designs have utilized either bicuspid or tricuspid valve designs.
- One of the key factors that determines the long term functionality of stented valves is the retrograde flow characteristics. The retrograde flow characteristics, along with the stiffness characteristics of the valve material, will determine leakage and closing pressure requirements. The retrograde flow characteristics are most important in low flow/low pressure systems where the valve leaflets may thrombose in the presence of poor retrograde laminar flow.
- Stented valves are passive devices. The valves function as a result of changes in pressure and flow. An aortic stented valve opens passively when the pressure in the left ventricle exceeds the pressure in the aorta (plus any resistance required to open the valve). The valve closes when the pressure in the left ventricle is less than the pressure in the aorta. However, the flow characteristics are critical to effect the closing of the aortic valve, otherwise regurgitation will ensue.
- Laminar flow is the normal condition found in most of the circulatory system. It is characterized by concentric layers of blood moving in parallel down the length of the blood vessel. The highest velocity is found in the middle of the blood vessel while the lowest is found along the wall. The flow is parabolic in a long straight vessel under steady flow conditions.
- Non-laminar, or turbulent, flow is useful to the circulatory system. For example, the aortic valve opens into the sinus of Valsalva at the inferior aspect of the ascending aorta. This sinus has two key functions: First, it maximizes the flow characteristics so that the aortic valve closes during diastole. And second, it optimizes coronary sinus flow and perfusion.
- Laminar flow makes the retrograde flow characteristics of valves mounted in cylindrical stents problematic as the flow along the wall is least, which is central to the closing of a valve. Such laminar flow with its attendant drawbacks is a characteristic of known stented valves. There is a need to have stented valves where the retrograde flow characteristics will be non-laminar, which will be advantageous with regard to valve closing.

FIG. 1 represents an oblique view of an embodiment of the invention: -
FIG. 2 represents a cross-sectional view across line 2-2 of the embodiment shown inFIG. 1 ; -
FIG. 3 represents an oblique, partly cross-sectional view of another embodiment of the invention; and -
FIG. 4 represents a cross-sectional view across line 4-4 of the embodiment shown inFIG. 3 . - A main aspect of the present invention is the introduction of several novel designs for an implantable prosthetic valve. Another aspect of the present invention is the disclosure of several manufacturing methods for implantable prosthetic valves in accordance with the present invention. A further aspect of the present invention is the provision of novel deployment and positioning techniques suitable for the valve of the present invention.
- Basically the implantable prosthetic valve of the present invention comprises a leaflet-valve assembly, preferably tricuspid but not limited to tricuspid valves only, consisting of a conduit having an inlet end and an outlet, made of pliant material arranged so as to present collapsible walls at the outlet. The valve assembly is mounted on a support structure or frame such as a stent adapted to be positioned at a target location within the body duct and deploy the valve assembly by the use of deploying means, such as a balloon catheter or similar devices. In embodiments suitable for safe and convenient percutaneous positioning and deployment the annular frame is able to be posed in two positions, a crimped position where the conduit passage cross-section presented is small so as to permit advancing the device towards its target location, and a deployed position where the frame is radial extended by forces exerted from within (by deploying means) so as to provide support against the body duct wall, secure the valve in position and open itself so as to allow flow through the conduit.
- The valve assembly can be made from biological matter, such as a natural tissue, pericardial tissue or other biological tissue. Alternatively, the valve assembly may be made form biocompatible polymers or similar materials. Homograph biological valves need occasional replacement (usually within 5 to 14 years), and this is a consideration the surgeon must take into account when selecting the proper valve implant according to the patient type. Mechanical valves, which have better durability qualities, carry the associated risk of long-term anticoagulation treatment.
- The frame can be made from shape memory alloys such as nickel titanium (nickel titanium shape memory alloys, or NiTi, as marketed, for example, under the brand name Nitinol), or other biocompatible metals. The percutaneously implantable embodiment of the implantable valve of the present invention has to be suitable for crimping into a narrow configuration for positioning and expandable to a wider, deployed configuration so as to anchor in position in the desired target location.
- The support stent is preferably annular, but may be provided in other shapes too, depending on the cross-section shape of the desired target location passage.
- Manufacturing of the implantable prosthetic valve of the present invention can be done in various methods, by using pericardium or, for example, by using artificial materials made by dipping, injection, electrospinning, rotation, ironing, or pressing.
- The attachment of the valve assembly to the support stent can be accomplished in several ways, such as by sewing it to several anchoring points on the support frame or stent, or riveting it, pinning it, adhering it, or welding it, to provide a valve assembly that is cast or molded over the support frame or stent, or use any other suitable way of attachment.
- To prevent leakage from the inlet it is optionally possible to roll up some slack wall of the inlet over the edge of the frame so as to present rolled-up sleeve-like portion at the inlet.
- Furthermore, floating supports may be added to enhance the stability of the device and prevent it from turning inside out.
- An important aspect of certain embodiments of the present invention is the provision of rigid support beams incorporated with the support stent that retains its longitudinal dimension while the entire support stent may be longitudinally or laterally extended.
- The aforementioned embodiments as well as other embodiments, manufacturing methods, different designs and different types of devices are discussed and explained below with reference to the accompanying drawings. Note that the drawings are only given for the purpose of understanding the present invention and presenting some preferred embodiments of the present invention, but this does in no way limit the scope of the present invention as defined in the appended claims.

FIGS. 1 and 2 illustrate a general tricuspid implantableprosthetic valve 10 in accordance with a preferred embodiment of the present invention, suitable for percutaneous deployment using an expandable stent or similar deploying means, shown in its deployed position.Valve 10 comprises avalve assembly 20 having aninlet 22 and anoutlet 24, the outlet walls consisting of collapsiblepliant leaflet material 26 that is arranged to collapse in a tricuspid arrangement.Valve assembly 20 is attached to anannular support stent 32, the one in this figure being a net-like frame designed to be adapted to crimp evenly so as to present a narrow configuration and be radially deployable so as to extend to occupy the passage at the target location for implantation in a body duct. Support beams 34 are provided onannular support stent 32 to provide anchorage tovalve assembly 20. Support beams 34 are optionally provided withbores 36 to allow stitching ofvalve assembly 20 to supportbeams 34 by thread, wire, or other attachment means. - The
proximal portion 38 ofsupport stent 32 is snuggly fit or fastened to the proximal portion ofvalve assembly 20 so that any flow is only intoinlet 22. Optionally the radial sections of eachleaflet 26 is closed by stitching, gluing or other means tonarrow outlet 24. Thedistal portion 42 ofsupport stent 32 is narrower thanproximal portion 38. The combination of the effect on flow characteristics due to the narrowing ofsupport stent 32 and the narrowing ofoutlet 24 is sufficient to engender the desired effect or flow characteristics, namely, non-laminar retrograde flow that will assist in the closing ofleaflets 26. - Another embodiment of the invention is shown in
FIGS. 3 and 4 . Aprosthetic valve 50 comprises avalve assembly 52 positioned within asupport stent 54. The proximal 56 and distal 58 portions ofsupport stent 54 are narrow as compared to the mid-portion 60 ofsupport stent 54, wherevalve assembly 52 is positioned. Within support stent mid-portion 60valve assembly 52 is preferably positioned co-axially and at a small distance, for example, from 0.5 to 3 cm, from theinterior surface 64 ofsupport stent 54.Valve assembly 52 is attached by connectingmembrane 66 to stent supports 68, which optimally have holes orprojections 70 to anchor saidmembranes 66. Any annular space betweeninterior surface 64 andvalve assembly 54 is filled with appropriate material to prevent flow aroundvalve assembly 54. Valve leaflets are shown in closed 72 and open 74 positions. -
Valve assembly 54 is shown in a closed position whereinleaflets 70 inhibit flow. - The effective cross-sectional area of
valve assembly 54 will preferably be from about 40 to 80% of the cross-sectional area acrosssupport stent midsection 60. - The preferred embodiments representing an implantable prosthetic valve in accordance with the present invention are relatively easy to manufacture as they are generally flat throughout most of the production process and only at the final stage of mounting the other elements of the valve assembly on the support frame, a three dimensional form is established.
- A typical size of an aortic prosthetic valve is from about 19 to about 26 mm in diameter. A maximal size of a catheter inserted into the femoral artery should be no more than 9 mm in diameter. The present invention introduces a device, which has the ability to change its diameter from about 4 mm to about 26 mm. Artificial valves are not new; however, artificial valves in accordance with the present invention posses the ability to change shape and size for the purpose of delivery and as such are novel. These newly designed valves require new manufacturing methods and technical inventions and improvements, some of which were described herein.
- As mentioned earlier, the material of which the valve is made from can be either biological or artificial. In any case new technologies are needed to create such a valve.
- To attach the valve to the body, the blood vessels determine the size during delivery, and the requirements for it to work efficiently, there is a need to mount it on a collapsible construction which can be crimped to a small size, be expanded to a larger size, and be strong enough to act as a support for the valve function. This construction, which is in somewhat similar to a large “stent”, can be made of different materials such as Nitinol, biocompatible stainless steel, polymeric material or a combination of all. Special requirement for the stent are a subject of some of the embodiments discussed herein.
- The mounting of the valve onto a collapsible stent is a new field of problems. New solutions to this problem are described herein.
- Another major aspect of the design of the valve of the present invention is the attachment to the body.
- In the traditional procedure the valve is sutured in place by a complicated suturing procedure. In the case of the percutaneous procedure there is no direct access to the implantation site therefore different attachment techniques are needed.
- Another new problem that is dealt herein is the delivery procedure, which is new and unique. Positioning of the device in the body in an accurate location and orientation requires special marking and measuring methods of the device and surgical site as was disclosed herein.
- Artificial polymer valves require special treatment and special conditions when kept on a shelf, as well as a special sterilization procedure. One of the consequences of the shelf treatment is the need to crimp the valve during the implantation procedure. A series of devices and inventions to allow the crimping procedure are disclosed herein.
- It should be clear that the description of the embodiments and attached Figures set forth in this specification serves only for a better understanding of the invention, without limiting its scope as covered by the following claims.
- It should also be clear that a person skilled in the art, after reading the present specification could make adjustments or amendments to the attached Figures and above described embodiments that would still be covered by the following claims.
