17 Claims, 9 Drawing Figures VA A A A A A A PATENIEBAUBI 31974 sum 2 BF 2 BACKGROUND OF THE INVENTION Holding structures are used with prosthetic heart valves during surgical procedures to facilitate the implantation of valves in the heart. These holders have elongated handles connected to collets. The valve base is releasably retained on the collets until the suturing member or skirt is attached to the heart tissue with sutures. The collet is then released, permitting the valve to function. The collet does not avoid the possibility of snagging a stitch over a portion of the valve or forcing portions of the valve into the heart tissue. Also, when the collet is removed from the valve, there is a possibility that one or more parts of the holding structure of the collet will be lost in the heart.

SUMMARY OF THE INVENTION The invention is related to a holder for a heart valve which facilitates the implantability of the valve. The

FIG. 8 is a top plan view of a heart valve mounted on the collet; and

FIG. 9 is a sectional view taken along line 9-9 of FIG. 8.

Referring to the drawings, there is shown in Fig. 1 a

- pivoting disc heart valve indicated generally at 10 carholder has a collet adapted to releasably accommodate a pivoting disc valve, as shown in US. Pat. No. 3,476,143 and US. patent application Ser. No. 124,754. The pivoting disc valve has an annular base carrying a suturing member. The base has a passage accommodating a pivoting disc which selectively moves to open and closed positions to allow flow of blood through the passage and restrict the flow of blood through the passage. Arm means secured to the base cooperate with the disc to retain the disc in assembled free-floating relation with the base. The collet has a body carrying a head. The head has an annular portion engageable with one side of the valve base and a groove for accommodating a portion of the disc to hold the disc in the open position. An elongated flexible band is secured to the head. The band is positionable over the arm means and the open disc to cover and protect the outer ends of the arms and the disc. The band also holds the valve in assembled relation with the collet. In use, the band prevents the possibility of snagging a stitch over an arm and forcing an arm into heart tissue, i.e., myocardium. The band has an end portion attached to the body to hold the valve base on the head and the band in protective engagement with the arms and disc. A section of the end portion of the band is exposed so that it can be cut after the valve has been implanted. The band'can only be cut in one place, thereby eliminating the possibility of having band or collet structural pieces being lost in the wound.

FIG. 2 is a plan view of the collet of the valve holder;

partly sectioned, of

rying an annular suturing member or collar 11. Valve 10 is mounted on a holder indicated generally at 12. Holder 12 has a collet 13 connected to an elongated handle 141. Holder 12 is used to position the valve in the heart and hold the valve in position during open heart surgery.

Heart valve I0 is a pivoting disc valve as shown in US. Pat. No. 3,476,143 and US. Pat. No. 3,737,919. Referring to FIG. 9, valve 10 has an annular base 16 having a passage 17 permitting the flow of blood through the base. Operatively located within passage 17 is an occluder or disc 18. The disc 18 is operable to pivot between open and closed positions. As shown in FIG. 9, the disc 18 is in its open position. A pair of side arms or struts 19 and 21 project upwardly from base. 16 in the direction of the opening pivot movement of the disc and cooperate with separate portions of the outer peripheral edge of the disc 18 to retain the disc in free floating pivotal relation with the base.

Returning to FIGS. 1 to 6, the collet 13 has a cylindrical body 22 of plastic material, as Teflon or Delrin. The upper end of the body 22 has an enlarged circular head 23. The top of the head has a flat surface or face 24. Face 24 has a diameter equal to the diameter of the proximal side of the base 16, as shown in FIG. 9. Face 24 has an annular surface that engages the proximal side of the base 16. An elongated flexible sheet member or band 26 is joined to the head 23 with connecting section 27. As shown in FIG. 5, connecting section 27 is integral with the head 23. The band 26 is a flexible plastic strap, as Teflon, made separately from the body 22. During the molding of the plastic body 22, connecting section 27 is molded into the head. Band 26 has a longitudinal ribbon or tail 28 extended longitudinally from an enlarged cover section 29. Section 29 has an elongated elliptical shape and has a width to cover the ends of the arms 19 and 21 and the upper outer peripheral edge of disc 18, as shown in FIG. 8.

As shown in FIGS. 5 and 6, the head 23 has a groove or semi-circular recess 30 inwardly of and adjacent the connecting section 27. The groove has an arcuate configuration corresponding to the curvature of the outer peripheral edge of the disc 18 and a slight inward incline. Groove 30 accommodates a peripheral portion of the disc, as shown in broken lines in FIG. 6, to hold the disc in an inclined open position when the valve is mounted on the collet 13. Located opposite groove 30 is an opening or passage 31. Passage 31 extends from surface 24 downwardly through the head 23. The upper portion of body 22 has a transverse passage 32. One end of passage 32 is longitudinally aligned with the-exit opening of passage 31. Body 22 has a longitudinal threaded passage 33 open to the transverse passage 32. As shown in FIGS. 1 and 9, a set screw 34 is threaded into the passage 33 and engages the ribbon 28.

The handle 14 has a threaded end 36 of size to be threaded into the open end of passage 33, as shown in FIG. I. The threaded end 36 is mounted on an elongated shaft or rod 37. The midsection of rod 37 has a pair of outwardly directed circular flanges 38 and 39 interposed between the flanges 38 and 39 is a triangular shaped flexible sheet member 41. Member 41 is a flexible sheet of plastic, rubber or like material used as a suture holder during the implant procedure. Member 41 can have other shapes, as square, round, and the like.

In use, as shown in FIGS. 8 and 9, the valve base 16 is positioned on the face 24. The disc 18 is an open position with a portion of the disc located in the recess 30. The flexible sheet member 26 extends upwardly through the passage 17 and over the ends 42 of arms 19 and 21 and over the upper outer peripheral edge 43 of the disc 18. The enlarged cover section 29 of the flexible sheet member 26 has a width and length sufficient to cover the opposite sides of disc 18 as well as the outer ends 42 of the arms 19 and 21. The ribbon 28 extends downwardly through the large opening 17 and through the passage 31. The end of ribbon 28 extends transversely through transverse passage 32. The flexible sheet member 26 is pulled tight to firmly engage the sheet member with the arms 19 and 21 and disc 18. The set screw 34 is turned into transverse groove 33 to hold the ribbon in a taut condition. The extreme outer end of the ribbon 28 is cut at 44, as indicated by broken lines in FIG. 9. Each mitral valve is shipped in assembled relation with a disposable collet 13. The valve is encased in the collet 13 so that it can be implanted after sterilization.

There are a variety of successful methods of implanting heart valves. Any of the standard methods are applicable to implantation of pivoting disc valves. The following discussion is one technique that can be used to implant the pivoting disc heart valve.

After the body cavity is opened, the heart is electrically fibrillated and opened to expose the diseased heart tissue. The diseased heart tissue is excised, leaving a 2-3 mm remnant of the patients own valve tissue. After the diseased valve tissue has been removed, the proper size prosthesis is selected by visual inspection aided by valve obturator sizers. The collet 13 on the selected valve is then turned into the handle end 36.

The valve placement is facilitated by initially placing four stay sutures equidistance about the annulus. A suture is placed at each commissure and one at the midpoints therebetween. Mattress sutures are placed in the heart tissue through the suturing collar and up through the suture holder 41. The handle 14 is then used to slide the heart valve into place within the annulus in the heart. The sutures are then tied with the valve holder in place. The head 23 and the band 26 over the ends of the arms 19 and 21 and the disc 18 prevent the sutures from being snagged or looped over arms 19 and 21 or around the base 17. in addition, the band 26 functions as a shield preventing the forcing of an arm into the heart tissue, i.e., myocardium.

The holder 12 is removed from the valve by cutting the ribbon 28 at the location 46 shown in FlG. 9. The collet 13 can be longitudinally moved from the valve base. One section of the ribbon is retained on the collet by set screw 34. The other section of the band 26 attached to head 23 will move around the arms 19 and 21 and disc 18, thereby eliminating the possibility of any foreign object being lost in the heart chamber.

If there are any subannular abnormalitites that appear to interfere with the free disc movement, the valve base can be rotated relative to the suturing member to orient the disc away from calcifications. The orientations of the disc is done after all of the stitches have been tied. Preferably, the valve disc is oriented so that the downward moving portion of the disc is toward the septum.

The atriotomy is then closed and the heart is allowed to restart by removing the fibrillatory electrodes and deflbrillating as necessary.

While there has been shown and described a preferred embodiment of the valve holding collet, it is understood that modifications, changes in size and material may be made by those skilled in the art without departing from the spirit of the invention.
