Definitions
- the present invention relates generally to the field of treating congestive heart failure and more specifically, to a device and method for partitioning a patient's heart chamber and a system for delivering the treatment device.
- Congestive heart failure is characterized by a progressive enlargement of the heart, particularly the left ventricle and is a major cause of death and disability in the United States. Approximately 500,000 cases occur annually in the U.S. alone. As the patient's heart enlarges, it cannot efficiently pump blood forward with each heart beat. In time, the heart becomes so enlarged the heart cannot adequately supply blood to the body. Even in healthy hearts only a certain percentage of the blood in a patient's left ventricle is pumped out or ejected from the chamber during each stroke of the heart. The pumped percentage, commonly referred to as the “ejection fraction”, is typically about sixty percent for a healthy heart. A patient with congestive heart failure can have an ejection fraction of less than 40% and sometimes lower.
- a patient with congestive heart failure is fatigued, unable to perform even simple tasks requiring exertion and experiences pain and discomfort.
- the internal heart valves such as the mitral valve, cannot adequately close.
- An incompetent mitral valve allows regurgitation of blood from the left ventricle back into the left atrium, further reducing the heart's ability to pump blood forewardly.
- Congestive heart failure can result from a variety of conditions, including viral infections, incompetent heart valves (e.g. mitral valve), ischemic conditions in the heart wall or a combination of these conditions.
- Prolonged ischemia and occlusion of coronary arteries can result in myocardial tissue in the ventricular wall dying and becoming scar tissue. Once the myocardial tissue dies, it is less contractile (sometimes non-contractile) and no longer contributes to the pumping action of the heart. It is referred to as hypokinetic.
- hypokinetic As the disease progresses, a local area of compromised myocardium may bulge out during the heart contractions, further decreasing the heart's ability to pump blood and further reducing the ejection fraction.
- the heart wall is referred to as dyskinetic or akinetic. The dyskinetic region of the heart wall may stretch and eventually form an aneurysmic bulge.
- Classes I, II, III and IV Patients suffering from congestive heart failure are commonly grouped into four classes, Classes I, II, III and IV.
- Drug therapy is presently the most commonly prescribed treatment.
- Drug therapy typically treats the symptoms of the disease and may slow the progression of the disease, but it can not cure the disease.

- The present invention relates generally to the field of treating congestive heart failure and more specifically, to a device and method for partitioning a patient's heart chamber and a system for delivering the treatment device.
- Congestive heart failure (CHF) is characterized by a progressive enlargement of the heart, particularly the left ventricle and is a major cause of death and disability in the United States. Approximately 500,000 cases occur annually in the U.S. alone. As the patient's heart enlarges, it cannot efficiently pump blood forward with each heart beat. In time, the heart becomes so enlarged the heart cannot adequately supply blood to the body. Even in healthy hearts only a certain percentage of the blood in a patient's left ventricle is pumped out or ejected from the chamber during each stroke of the heart. The pumped percentage, commonly referred to as the “ejection fraction”, is typically about sixty percent for a healthy heart. A patient with congestive heart failure can have an ejection fraction of less than 40% and sometimes lower. As a result of the low ejection fraction, a patient with congestive heart failure is fatigued, unable to perform even simple tasks requiring exertion and experiences pain and discomfort. Further, as the heart enlarges, the internal heart valves such as the mitral valve, cannot adequately close. An incompetent mitral valve allows regurgitation of blood from the left ventricle back into the left atrium, further reducing the heart's ability to pump blood forewardly.
- Congestive heart failure can result from a variety of conditions, including viral infections, incompetent heart valves (e.g. mitral valve), ischemic conditions in the heart wall or a combination of these conditions. Prolonged ischemia and occlusion of coronary arteries can result in myocardial tissue in the ventricular wall dying and becoming scar tissue. Once the myocardial tissue dies, it is less contractile (sometimes non-contractile) and no longer contributes to the pumping action of the heart. It is referred to as hypokinetic. As the disease progresses, a local area of compromised myocardium may bulge out during the heart contractions, further decreasing the heart's ability to pump blood and further reducing the ejection fraction. In this instance, the heart wall is referred to as dyskinetic or akinetic. The dyskinetic region of the heart wall may stretch and eventually form an aneurysmic bulge.
- Patients suffering from congestive heart failure are commonly grouped into four classes, Classes I, II, III and IV. In the early stages, Classes I and II, drug therapy is presently the most commonly prescribed treatment. Drug therapy typically treats the symptoms of the disease and may slow the progression of the disease, but it can not cure the disease. Presently, the only permanent treatment for congestive heart disease is heart transplantation, but heart transplant procedures are very risky, extremely invasive and expensive and are performed on a small percentage of patients. Many patient's do not qualify for heart transplant for failure to meet any one of a number of qualifying criteria, and, Furthermore, there are not enough hearts available for transplant to meet the needs of CHF patients who do qualify.
- Substantial effort has been made to find alternative treatments for congestive heart disease. For example, surgical procedures have been developed to dissect and remove weakened portions of the ventricular wall in order to reduce heart volume. This procedure is highly invasive, risky and expensive and is commonly only done in conjunction with other procedures (such as heart valve replacement or coronary artery by-pass graft). Additionally, the surgical treatment is usually limited to Class IV patients and, accordingly, is not an option for patients facing ineffective drug treatment prior to Class IV. Finally, if the procedure fails, emergency heart transplant is the only presently available option.
- Other efforts to treat CHF include the use of an elastic support, such as an artificial elastic sock placed around the heart to prevent further deleterious remodeling.
- Additionally, mechanical assist devices have been developed as intermediate procedures for treating congestive heart disease. Such devices include left ventricular assist devices and total artificial hearts. A left ventricular assist device includes a mechanical pump for increasing blood flow from the left ventricle into the aorta. Total artificial heart devices, such as the Jarvik heart, are usually used only as temporary measures while a patient awaits a donor heart for transplant.
- Recently, improvements have been made in treating patient's with CHF by implanting pacing leads in both sides of the heart in order to coordinate the contraction of both ventricles of the heart. This technique has been shown to improve hemodynamic performance and can result in increased ejection fraction from the right ventricle to the patient's lungs and the ejection fraction from the left ventricle to the patient's aorta. While this procedure has been found to be successful in providing some relief from CHF symptoms and slowed the progression of the disease, it has not been able to stop the disease.
- The present invention is directed to a ventricular partitioning device and method of employing the device in the treatment of a patient with congestive heart failure. Specifically, the ventricular chamber of the CHF patient is partitioned by the device so as to reduce its total volume and to reduce the stress applied to the heart and, as a result, improve the ejection fraction thereof.
- A ventricular partitioning device embodying features of the invention has a reinforced membrane component, preferably self expanding, which is configured to partition the patient's ventricular heart chamber into a main productive portion and a secondary non-productive portion, and a support or spacing component extending from the distal side of the reinforced membrane for non-traumatically engaging a region of the patient's ventricular wall defining in part the secondary non-productive portion to space a central portion of the reinforced membrane from the heart wall. The partitioning device preferably includes a centrally located hub secured to the reinforced membrane. The partitioning membrane of the device may be reinforced by a radially expandable frame component formed of a plurality of ribs.
- The ribs of the expandable frame have distal ends secured to the central hub, preferably secured to facilitate abduction of the free proximal ends of the ribs away from a centerline axis. The distal ends of the ribs may be pivotally mounted or formed of material such as superelastic NiTi alloy which allow for compressing the ribs into a contracted configuration and when released allow for their self expansion. The ribs also have free proximal ends configured to engage and preferably penetrate the tissue of the heart wall so as to secure the peripheral edge of the membrane to the heart wall and fix the position of the membrane with respect thereto. The free proximal ends of the ribs may have tissue penetrating tips such as barbs or hooks. The partitioning membrane is secured to the ribs of the expandable frame, preferably on the proximal or pressure side of the expandable frame.
- The supporting component or stem of the device has a length configured to extend to the heart wall (typically about 5 mm to about 50 mm, preferably about 15 to about 35 mm), to support and space the membrane from the heart wall. While only one supporting component or stem is described herein, a plurality of such components may be utilized. The supporting component or stem may have at least one inner lumen extending therein for delivery of therapeutic or diagnostic agents through the ports provided along the length thereof. The stem is provided with one or more flexible bumper-type elements on its distal end to non-traumatically engage the weakened ventricular wall and maintain the reinforced membrane, preferably the central portion thereof, spaced a desired distance from the weakened ventricular wall.
- The partitioning membrane in the expanded configuration has radial dimensions from about 10 to about 160 mm, preferably about 50 to about 100 mm, as measured from the center line axis.
- The partitioning device may be delivered percutaneously or intraoperatively. It is relatively easy to install and provides substantial improvement in the ejection fraction of the patient's heart chamber. These and other advantages of the invention will become more apparent from the following detailed description of the invention and the accompanying exemplary drawings.

FIGS. 1-5 illustrate apartitioning device 10 which embodies features of the invention and which includes apartitioning membrane 11, astem 12 and a radially expandable reinforcingframe 13 formed of a plurality ofribs 14. Preferably themembrane 11 is secured to the proximal or pressure side of theframe 13 as shown inFIG. 1 . The distal ends 15 of theribs 14 are secured to thecentral hub 16 and the proximal ends 17 of theribs 14 are unsecured and are configured to radially extend away from acenter line axis 18 which extends through thehub 16. Radial expansion of the free proximal ends 17 unfurls themembrane 11 secured to theframe 13 so that the membrane presents a relatively smooth pressure side surface.Stem 12 extends distally from thehub 16 and has adistal end 19 which has a flexible, J-shape bumper element 20 to provide a yielding engagement with a heart wall when deployed within a patient's heart chamber. Theframe 13 and attachedmembrane 11 are collapsible toward thecenterline axis 18 for delivery through a catheter. - The proximal or free ends 17 of
ribs 14 are provided withsharp tip elements 21 which are configured to hold theframe 13 and themembrane 11 secured thereto in a deployed position within the patient's heart chamber. Preferably, thesharp tip elements 21 of theframe 13 penetrate into tissue of the patient's heart wall in order to secure the reinforcedmembrane 11 so as to partition the ventricular chamber in a desired manner. - As shown in
FIG. 1 , thestem 12 is provided with aninner lumen 22 for delivery of fluid to the non-operative portion of the ventricular chamber anddischarge ports 23 are provided in the stem. Thehub 16 is secured within theinner lumen 22 in the proximal end ofstem 12 suitable means such as a friction fit, an adhesive bond or a pin. Thehub 16 has adeployment pin 24, as shown inFIG. 5 , which as will be described later allows thepartitioning device 10 to be deployed within the patient's heart chamber and released from a delivery system used to place the device. The distal ends of the reinforcingribs 14 are secured to thehub 16 in a suitable manner. They may be secured to the surface defining the inner lumen or the hub may be provided with channels or bores in the wall of the hub into which the distal ends of the ribs may be secured. Theribs 14 are preshaped so that when not constrained (as shown inFIGS. 1 and 2 ), the free proximal ends 17 thereof expand to a desired angular displacement (.theta.) away from acenter line axis 18 which is about 20.degree. to about 90.degree., preferably about 50.degree. to about 80.degree. -
FIGS. 2-4 illustrate asuitable delivery system 30 with apartitioning component device 10 as shown inFIG. 1 . Thedelivery system 30 includes acontrol handle 31 with adelivery catheter 32 having a deployingcoil screw 33 secured to thedistal end 34 for releasing thepartitioning device 10 from thedelivery system 30. Thedelivery catheter 32 has aninner lumen 35 through which therapeutic or diagnostic fluids may be delivered. Thedelivery catheter 32 extends through thehandle 31 and the proximal end of thecatheter 32 is secured to torquingknob 36 to allow rotation of the catheter by rotatingknob 36. Aninjection port 37 is provided in fluid communication with thedelivery catheter 32 for injecting therapeutic or diagnostic fluids through theinner lumen 35. - The
delivery system 30 may be introduced into a patient's body through guiding catheter orcannula 40 which has aninner lumen 41. A radiopaque marker (not shown) may be provided on the distal end of the guidingcatheter 40 to aid in fluoroscopically guiding the catheter to the desired location. Thepartitioning device 10 is slidably disposed within theinner lumen 41 with the free proximal ends 17 of theribs 14 in a constricted configuration. The guidingcatheter 40 is percutaneously introduced in a conventional fashion into the patient's vasculature and advanced therein until thedistal end 42 of the guidingcatheter 40 is position close to the desired location for thepartitioning device 10 within the patient's heart chamber such as the left ventricle. Thedelivery system 30 is advanced distally within theinner lumen 41 until the J-shapedbumper 20 extends out thedistal end 42 of the guidingcatheter 40 and engages the ventricular wall. With thedelivery system 30 held in place and thebumper 20 engaging the ventricular wall, theguide catheter 40 is pulled proximally until the free ends 17 ofribs 14 are released from thedistal end 42 so that anchoringtip elements 21 on the free proximal ends 17 ofribs 14 penetrate into tissue of the patient's heart wall as shown inFIG. 6 to secure thepartitioning device 10 within the patient's heart chamber. With thepartitioning device 10 properly positioned within the heart chamber, thedelivery catheter 32 is rotated counter-clockwise to disengage thedelivery system 30 from thehub 16. Upon the counter-clockwise rotation of thedelivery catheter 32, thehelical coil screw 33 attached to thedistal end 34 of thedelivery catheter 32 rides on thedeployment pin 24 secured within theinner lumen 22 of thehub 16. Thedelivery system 30 and theguide catheter 40 may then be removed from the patient. The proximal end of theguide catheter 40 is provided with aninjection port 43 to inject therapeutic or diagnostic fluids through theinner lumen 41. -
FIG. 6 illustrates the placement of partitioningdevice 10 within a patient'sleft ventricle 45. Themembrane 11 secured to the proximal side ofribs 14 partitions the patient'sheart chamber 45 into a main productive oroperational portion 46 and a secondary, essentiallynon-productive portion 47. Theoperational portion 46 is much smaller than theoriginal ventricular chamber 45 and provides for an improved ejection fraction. The partitioning increases the ejection fraction and provides an improvement in blood flow. Over time, thenon-productive portion 47 fills initially with thrombus and subsequently cellular growth. Bio-resorbable fillers such as polylactic acid, polyglycolic acid, polycaprolactone and copolymers and blends may be employed to fill thenon-productive portion 47. Fillers may be suitably supplied in a suitable solvent such as DMSO. Other materials which accelerate tissue growth may be deployed in thenon-productive portion 47. -
FIGS. 7-12 illustrate distal ends 19 of the partitioning devices having alternative bumper elements for providing non-traumatic contact with a weakened ventricular wall. InFIG. 7 thedistal end 19 ofstem 12 has a pair of J-shapedbumpers FIG. 8 thedistal end 19 has three J-shapedbumpers FIG. 9 illustrates adistal end 19 having three J-shapedbumpers FIG. 10 depicts a slight change, where thedistal end 19 has four wire J-shaped bumpers 59-62 (not shown in drawing) with sharp tips 63-66 (not shown) for securing the ends of the bumpers in heart tissue. A further alternative is illustrated inFIG. 11 where amembrane 68 is applied to the J-shaped bumpers InFIG. 12 , thedistal end 19 ofstem 12 is provided with a coiled bumper 70 for engaging a ventricular wall. - Another modification is shown in
FIG. 13 wherein aninflatable balloon 80 is provided on the distal side of theframe 13 to support and space thepartitioning device 10 from a patient's ventricular wall in lieu of the stem with flexible bumpers, as shown in the partitioning devices previously described. - The
ribs 14 of the partitioning device have a length of about 1 to about 8 cm, preferably, about 1.5 to about 4 cm for most left ventricle deployments. To assist in properly locating the device during advancement and placement thereof into a patient's heart chamber, the distal extremity of one or more of the ribs and/or the stem may be provided with markers at desirable locations that provide enhanced visualization by eye, by ultrasound, by X-ray, or other imaging or visualization means. Radiopaque markers may be made with, for example, stainless steel, platinum, gold, iridium, tantalum, tungsten, silver, rhodium, nickel, bismuth, other radiopaque metals, alloys and oxides of these metals. - The
membrane 11 may be formed of suitable biocompatitble polymeric material which include ePTFE (expanded polytetrafluoroethylene), Nylon, PET (polyethylene terephthalate) and polyesters such as Hytrel. Themembrane 11 is preferably foraminous in nature to facilitate tissue ingrowth after deployment within the patient's heart. The delivery catheter and the guiding catheter may be formed of suitable high strength polymeric material such as PEEK (polyetheretherketone), polycarbonate, PET, Nylon, and the like. Braided composite shafts may also be employed. To the extent not otherwise described herein, the various components of the partitioning device and delivery system may be formed of conventional materials and in a conventional manner as will be appreciated by those skilled in the art. - While particular forms of the invention have been illustrated and described herein, it will be apparent that various modifications and improvements can be made to the invention.
