Definitions
- the present invention relates to a steerable guidewire, and more particularly to a bi-directional steerable guidewire having a tip which may be very precisely “steered,” or deflected.
- the guidewire is particularly suitable for use in conjunction with the insertion of a catheter into a vessel of the body, or alternatively, the guidewire may be used by itself to open obstructions within a vessel or to carry a therapeutic device for removing obstructions within a vessel.
- guidewires have included a core wire with the distal end being tapered and with a coil spring mounted on the tapered distal end. These guidewires have been used to facilitate the insertion of a catheter into a vessel of the body. Generally, the guidewire is inserted into a vessel, a catheter is inserted over the guidewire and the catheter is then moved through the vessel until the distal end of the catheter is positioned at a desired location. The guidewire is then retracted from the catheter and the catheter is left in the vessel. Alternatively, the guidewire may be first inserted into the catheter with the distal portion of the guidewire extending beyond the distal end of the catheter.
- This assembly is then inserted into a vessel with the distal tip of the guidewire being used to facilitate movement of the guidewire and catheter through the vessel. Again, when the distal tip of the catheter has been placed in a desired location, the guidewire may be retracted thereby leaving the catheter in place within the vessel.
- Another common application for guidewires is that of using the distal tip of the guidewire for removing an obstruction within a vessel. Often times this procedure is accomplished by inserting the guidewire within a vessel, moving the distal tip of the guidewire into contact with the obstruction and then very gently tapping the distal tip of the guidewire against the obstruction until the guidewire passes through the obstruction.
- various types of devices may be placed on the distal end of a guidewire for actively opening an obstruction within the vessel. Examples of such devices which may be placed on the end of the guidewires are disclosed in the following United States patents to Robert C. Stevens: U.S. Pat. Nos. 5,116,350; 5,078,722; 4 , 936 , 845 ; 4 , 923 , 462 ; and, 4 , 854 , 325 .

Description
- This patent application is a divisional patent application of U.S. patent application Ser. No. 10/224,168, filed on Aug. 20, 2002, entitled “Guidewire With Deflectable Tip”, which claims benefit of provisional patent application, U.S. Ser. No. 60/366,739 filed on Mar. 22, 2002.
- 1. Field of the Invention
- The present invention relates to a steerable guidewire, and more particularly to a bi-directional steerable guidewire having a tip which may be very precisely “steered,” or deflected. The guidewire is particularly suitable for use in conjunction with the insertion of a catheter into a vessel of the body, or alternatively, the guidewire may be used by itself to open obstructions within a vessel or to carry a therapeutic device for removing obstructions within a vessel.
- 2. Description of the Prior Art
- For many years guidewires have included a core wire with the distal end being tapered and with a coil spring mounted on the tapered distal end. These guidewires have been used to facilitate the insertion of a catheter into a vessel of the body. Generally, the guidewire is inserted into a vessel, a catheter is inserted over the guidewire and the catheter is then moved through the vessel until the distal end of the catheter is positioned at a desired location. The guidewire is then retracted from the catheter and the catheter is left in the vessel. Alternatively, the guidewire may be first inserted into the catheter with the distal portion of the guidewire extending beyond the distal end of the catheter. This assembly is then inserted into a vessel with the distal tip of the guidewire being used to facilitate movement of the guidewire and catheter through the vessel. Again, when the distal tip of the catheter has been placed in a desired location, the guidewire may be retracted thereby leaving the catheter in place within the vessel.
- Another common application for guidewires is that of using the distal tip of the guidewire for removing an obstruction within a vessel. Often times this procedure is accomplished by inserting the guidewire within a vessel, moving the distal tip of the guidewire into contact with the obstruction and then very gently tapping the distal tip of the guidewire against the obstruction until the guidewire passes through the obstruction. Alternatively, various types of devices may be placed on the distal end of a guidewire for actively opening an obstruction within the vessel. Examples of such devices which may be placed on the end of the guidewires are disclosed in the following United States patents to Robert C. Stevens: U.S. Pat. Nos. 5,116,350; 5,078,722; 4,936,845; 4,923,462; and, 4,854,325.
- While most guidewires used today do not include a mechanism for deflecting or steering the tip of the guidewire, it is very desirable to provide tip steering in order to facilitate movement of the guidewire through the tortuous vessels of the body. There are many patents directed toward different mechanisms for deflecting the distal tip of a guidewire in order to steer the guidewire. Examples of such guidewires are disclosed in the following patents: U.S. Pat. No. 4,815,478 to Maurice Buchbinder, et al., U.S. Pat. No. 4,813,434 to Maurice Buchbinder, et al., U.S. Pat. No. 5,037,391 to Julius G. Hammerslag, et al., U.S. Pat. No. 5,203,772 to Gary R. Hammerslag, et al., U.S. Pat. No. 6,146,338 to Kenneth C. Gardeski, et al., U.S. Pat. No. 6,126,649 to Robert A. VanTassel, et al., U.S. Pat. No. 6,059,739 to James C. Baumann and U.S. Pat. No. 5,372,587 to Julius G. Hammerslag, et al. U.S. Pat. No. 4,940,062 to Hilary J. Hampton, et al., discloses a balloon catheter having a steerable tip section. All of the above-identified patents are incorporated herein by reference.
- While each of the latter group of patents disclose guidewires having some degree of steerability, there is a need to have a guidewire with very precise steering in a guidewire of a very small diameter which is suitable for the purposes described above. More particularly, there is an important need for a very small diameter guidewire having a distal tip which may be deflected very precisely in either of two directions to enhance steerability and which is suitable for vascular applications.
- In accordance with one aspect of the present invention, there is provided a very small diameter steerable guidewire having a deflectable tip which includes an elongated flexible tubing, a flexible helical coil attached to the distal portion of the flexible tubing, an elongated deflection member which is slidably disposed within the tubing and within the helical coil. The proximal portion of the deflection member is of a cylindrical configuration and the distal portion is tapered to form a deflection ribbon. Alternatively, the deflection member may take the form of a proximal cylindrical wire which is attached at its distal end to a deflection ribbon. In addition, a retaining ribbon is attached to the distal end of the flexible tubing and is oriented to extend in a plane which is generally parallel to the plane of the ribbon portion of the deflection member. An attachment member which may take the form of a rounded bead, preferably formed from epoxy, is bonded to the distal end of the helical coil, the distal end of the deflection ribbon and the distal end of the retaining ribbon so that longitudinal movement of the deflection member causes the distal end of the helical coil to be deflected.
- In accordance with another aspect of the present invention, the retaining ribbon and the deflection ribbon are preferably pre-shaped into a curved configuration to thereby cause the flexible helical coil to be biased into a normally curved shape.
- In accordance with a further aspect of the present invention, the distal portion of the deflection ribbon engages the attachment member, or rounded bead, at a location offset from the center of the attachment member, and the distal portion of the retaining ribbon engages the attachment member at a location offset from the center of the attachment member. Preferably, the retaining ribbon engages the attachment member at a location offset from the center portion of the attachment member in the opposite direction from the offset location of the deflection ribbon.
- In accordance with still another aspect of the present invention, the deflection ribbon and the retaining ribbon are connected to each other within the attachment member. Preferably these two elements are formed as a single unitary element. In a preferred embodiment of the invention the cylindrical deflection member is flattened to form the deflection ribbon and is further flattened at its distal end to form the retaining ribbon. The retaining ribbon is bent 180 degrees with respect to the deflection ribbon to form a generally U-shaped bend to thereby establish a predetermined spacing between the ribbons and to also cause these ribbons to remain parallel to each other.

FIG. 1 generally illustrates asteerable guidewire system 10 which embodies the present invention and comprises a steerable guidewire 12 coupled to acontrol handle 14. More particularly, the steerable guidewire comprises anelongated hypotube 16, ahelical coil 18 attached to and extending from the distal end of thehypotube 16. Thehelical coil 18 is preferably formed from platinum tungsten with the proximal turns being wound such that adjacent turns of the proximal portion are in contact with each other. - While the preferred embodiment of the present invention includes the
helical coil 18, this element may take the form of any flexible cylindrical member, such as for example a thin metallic tube with or without portions of the tube removed by, for example laser cutting, so as to form a very flexible cylindrical member. Anelongated deflection member 20 extends from the proximal end of the control handle through thehypotube 16 and through thehelical coil 18, and is connected into an attachment member, orrounded bead 22, which is disposed at the distal tip of thehelical coil 18. In addition, aretaining ribbon 24 is connected to the distal end of thehypotube 16 and is also connected to therounded bead 22. - The
control handle 14 generally comprises aslidable control knob 26 which may be moved longitudinally with respect to the control handle. The control handle 14 is coupled to thedeflection member 20. As will be discussed in more detail, the longitudinal movement of theslidable control knob 26 causes deflection of the distal tip of the guidewire in either an upward or downward direction. -
FIGS. 2 and 3 illustrate in more detail the distal portion of the steerable guidewire 12. As may be appreciated,FIG. 3 is a view of the guidewire 12 shown inFIG. 2 with the guidewire being rotated 90 degrees about its longitudinal axis. More particularly, the proximal end of thehelical coil 18 is bonded, preferably by use of an epoxy, to the outer surface near the distal end of thehypotube 16. Theelongated deflection member 20 takes the form of a small diametercylindrical deflection member 20 having an intermediate portion which is flattened to form athin deflection ribbon 34 having a thickness of approximately 0.002 inches. The distal end of thecylindrical deflection member 20 is further flattened to a thickness of approximately 0.0015 inches and is bent back 180 degrees to form aU-shaped bend 26 a between thedeflection ribbon 34 and the retainingribbon 24. The proximal end of the retainingribbon 24 is bonded, preferably by use of epoxy, to the outer surface of the distal end of thehypotube 16. The retainingribbon 24 is aligned in a plane parallel to the plane of thedeflection ribbon 34 and the U-shaped portion between the ribbons is encapsulated by the attachment member which preferably takes the form of arounded epoxy bead 22 bonded to the distal tip of thehelical coil 18. - As may be appreciated, with this unitary construction of the ribbon members, these members remain aligned so that both lie in planes parallel to each other. In addition, the U-shaped bend portion when encapsulated into the
rounded bead 22 causes the retaining ribbon and deflection ribbon to be properly spaced with respect to each other. - As illustrated in
FIG. 2 , the retainingribbon 24 is preferably attached to the roundedbead 22 at a position offset from the center of the bead in the same direction that the retainingribbon 24 is offset from the longitudinal axis of the steerable guidewire 12. In addition, thedeflection ribbon 34 is attached to the bead at a position offset from the center of the bead in an opposite direction from the offset of the retainingribbon 24. - Also, as may be seen in
FIG. 2 , thedeflection ribbon 34 and the retainingribbon 24 are pre-shaped into an arcuate, or curved, configuration to thereby maintain thehelical coil 18 in a normally curved configuration. Theribbons ribbon 24. -
FIG. 4 illustrates in more detail the control handle 14 which includes acylindrical body portion 38 with theslidable control knob 26 being mounted for longitudinal movement along thecylindrical body portion 38 of the control handle 14. The pair ofset screws 28, 30 extend through theslidable control knob 26 and lock onto theelongated deflection member 20 which extends through the control handle 14. In addition, the control handle 14 includes a coaxial hypotube 40 which is disposed about thedeflection member 20 and which is locked in place within the control handle by another set ofset screws 32, 33. The coaxial hypotube 40 serves to prevent thedeflection member 20 from buckling as the slidable control knob is moved in a distal direction. Still further, the control handle 14 includes apin vise 36 which serves to clamp onto thedeflection member 20. - In operation, as previously described, the distal tip of the steerable guidewire 12 is normally biased into a downwardly curved position as illustrated in
FIG. 2 because of the curve of thepre-shaped deflection ribbon 34 and the retainingribbon 24. When theslidable control knob 26 is moved distally, thedeflection member 20 will be moved distally thereby causing thedeflection ribbon 34 to move in a distal direction. As the deflection ribbon is moved distally, a force is applied to the top portion of the roundedbead 22. The retainingribbon 24 is attached to the lower portion of thebead 22 to thereby maintain the bead at a fixed distance from the distal end of thehypotube 16. As thedeflection ribbon 34 is moved to the right, the tip of the guidewire is caused to deflect downwardly to a maximum position of deflection as shown inFIG. 5A . Since thedeflection ribbon 34 and the retainingribbon 24 are pre-shaped prior to any activation of the steerable guidewire, the amount of force required to deflect the guidewire in this direction is very small thereby preventing buckling of thedeflection ribbon 34 as the deflection ribbon is pushed distally. As thedeflection ribbon 34 is moved distally, the upper turns of the helical coil become slightly stretched and the lower turns of the coil become slightly compressed. Thedeflection member 20 has a diameter of about 0.0065 inches and the deflection ribbon has a thickness of about 0.002 inches to thereby provide sufficient stiffness to prevent the buckling of these elements when thedeflection member 20 is pushed distally. This construction also provides sufficient stiffness to transmit the necessary force to the distal tip of the guidewire. - When the
slidable control knob 26 is moved in a proximal direction (to the left inFIG. 4 ) thedeflection member 20 will be pulled to the left to thereby cause thedeflection ribbon 34 to pull on the top portion of thebead 22. Since again the retainingribbon 24 causes the lower portion of the bead to remain at a fixed distance from the distal end of thehypotube 16, the tip of the guidewire 12 is caused to bend in an upward direction to a maximum deflection as shown inFIG. 5 . Since thedeflection ribbon 34 is in tension when thedeflection member 20 is pulled, there is no concern for buckling of thedeflection ribbon 34. As thedeflection ribbon 34 is moved proximally as shown inFIG. 5 , the upper coil turns become slightly compressed and the lower coil turns become somewhat stretched. - In a preferred embodiment of the present invention, the
elongated deflection member 20, retainingribbon 24 anddeflection ribbon 34 are constructed of nitinol, but these elements may be formed from other flexible materials including polymers. Thehelical coil 18 preferably has an outside coil diameter of about 0.013 inches and is constructed from an alloy comprised of about 92 percent platinum and 8 percent tungsten, but this element may also be constructed from numerous other materials. It is desirable that the coil exhibit the characteristic of being radiopaque to X-rays to assist in the positioning of the distal tip of the steerable guidewire 12. Thedeflection member 20 is formed from a single cylindrical nitinol wire of about 0.0065 inches in diameter having an intermediate portion which is flattened to form thedeflection ribbon 34 with a thickness of about 0.002 inches, and a distal portion which is flattened to form the retainingribbon 24 with a thickness of about 0.0015 inches. The retainingribbon 24 is bent back 180 degrees to form a generally U-shaped bend, which is subsequently encapsulated within the roundedbead 22. Therounded bead 22 is preferably formed with epoxy, but may be formed with soldering or by welding. - It has been found that the addition of graphite between the
deflection member 20 anddeflection ribbon 34, and the inner lumen of thehypotube 16 provides lubrication. Other lubricants, such as Teflon or MDX may be used for this purpose. Thehelical coil 18 is preferably coated with anelastomeric polymer 41 on its distal end to act as a sealant preventing the entry of blood and contrast media into the guidewire and afluorinated polymer 39, such as Teflon, on its proximal end for lubrication purposes. - It may be seen that the guidewire as disclosed may be very easily and very precisely deflected in either of two directions for very precise steering of the guidewire through the vessels of the body. As may be apparent, the disclosed guidewire may be used for placement of a catheter within the vasculature of the human body, it may be used by itself to cross an obstruction within the vessels or it may be used to carry a therapeutic device mounted on the distal end of the guidewire for purposes of removing obstructions which may exist within a vessel of the body.
- The preceding specific embodiment is illustrated of the practice of this invention. It is to be understood, however, that other variations may also be employed without departing from the spirit and scope of the invention as hereinafter claimed.
