Method and apparatus for heart valve surgery
View Patent ↗A method for heart valve surgery may include providing a cardiac valve ring and suture loops connected to the cardiac valve ring, accessing a valve annulus of the heart of the patient, stapling at least one of the sutures loop to the valve annulus, and parachuting the cardiac valve ring down the suture to the valve annulus after the stapling. The cardiac valve ring may be an annuloplasty ring, a replacement heart valve, or other medical device.
1. A surgical apparatus, comprising:
a plurality of suture loops; and
a cardiac valve ring, wherein said cardiac valve ring includes a plurality of apertures defined therethrough and a tab associated with at least one said aperture, wherein each suture loop end of said plurality of suture loops passes through at least one said aperture; and
wherein at least part of said tab is spaced from said aperture a distance less than the diameter of a suture strand of one of the plurality of suture loops, and
wherein a portion of at least one said tab is integrally formed with said cardiac valve ring and is attached adjacent a side of said aperture that is opposite that from which ends of said suture loops extend.
2. The apparatus of claim 1 , wherein said cardiac valve ring is an annuloplasty ring.
3. The apparatus of claim 1 , wherein at least one said aperture is substantially cylindrical.
4. The apparatus of claim 1 , wherein at least one said suture loop is U-shaped.
5. The apparatus of claim 1 , wherein at least one said suture loop is composed of polypropylene.
6. A surgical apparatus, comprising:
a cardiac valve ring having a plurality of unidirectional suture holding features associated therewith; and
a plurality of suture loops connected to said cardiac valve ring; wherein each said suture loop is formed from a single length of suture independent from the other said suture loops, wherein each suture end passes through at least one said unidirectional suture holder feature in said cardiac valve ring; wherein at least one unidirectional suture holding feature comprises:
an aperture defined through said cardiac valve ring, wherein one strand of said suture passes through said aperture, and
a tab associated with said aperture, wherein at least part of said tab is spaced from said aperture a distance less than the diameter of said suture, wherein a portion of the tab is integrally formed with the cardiac valve ring and is positioned adjacent a side of said aperture that is opposite that from which end of said suture extend.
7. The surgical apparatus of claim 6 , wherein said cardiac valve ring is an annuloplasty ring.
8. The surgical apparatus of claim 6 , wherein said aperture is substantially cylindrical.
9. A surgical apparatus, comprising:
a plurality of suture loops; and
a cardiac valve ring having a plurality of apertures defined therethrough and a tab associated with at least one of the plurality of apertures, wherein at least part of the tab is spaced from one of the plurality of apertures a distance less than the diameter of a suture strand of one of said plurality of suture loops, wherein a portion of the tab is integrally formed with the cardiac valve ring;
wherein each suture loop end of said plurality of suture loops passes through a corresponding said aperture between said tab and a perimeter of said aperture.
10. The surgical apparatus of claim 9 , wherein said cardiac valve ring is an annuloplasty ring.
11. The surgical apparatus of claim 8 , wherein at least one said aperture is substantially cylindrical.
12. The surgical apparatus of claim 9 , wherein a further portion of at least one said tab deflects above a surface of said cardiac valve ring while the portion of said tab is integral with said cardiac valve ring, and wherein said tab is coplanar with the surface of said cardiac valve ring when in a non-deflected position.
13. The surgical apparatus of claim 1 , wherein a further portion of at least one said tab deflects above a surface of the said cardiac valve ring while the portion of said tab is integral with said cardiac valve ring, and wherein said tab is coplanar with the surface of said cardiac valve ring when in a non-deflected position.
14. The surgical apparatus of claim 6 , wherein a further portion of at least one said tab deflects above a surface of said cardiac valve ring while the portion of said tab is integral with said cardiac valve ring, and wherein said tab is coplanar with the surface of said cardiac valve ring when in a non-deflected position.
