Jacket for surgical heart valve
Various aspects of the present disclosure are directed toward apparatuses, systems, and methods that include a prosthetic valve. The prosthetic valve may include a jacket configured to cover at least one of gaps, spaces, or interfaces in a frame or between one or more leaflets attached to the frame.
1. A jacket for a prosthetic valve comprising a frame and a sewing cuff and including an inflow side and an outflow side, the jacket comprising:
a first portion operable to be coupled to the outflow side of the prosthetic valve, the first portion having a first height; and
a second portion operable to be coupled to the inflow side of the prosthetic valve, the second portion having a second height,
wherein the first portion and the second portion are operable to be coupled together about the frame of the prosthetic valve; and
wherein the first portion and the second portion at least partially cover an interface between the frame and the sewing cuff of the prosthetic valve.
2. The jacket of claim 1 , wherein the first and the second portions are operable to be secured together by at least one of a swaging, a snap fit, a click fit, one or more staples, tape, adhesives, one or more screws, one or more rivets, insert molding, or overmolding.
3. The jacket of claim 1 , wherein the first portion and the second portion are operable to at least partially cover an interface between one or more leaflets of the prosthetic valve and the frame.
4. The jacket of claim 1 , wherein the first portion includes a post cover portion operable to cover a commissure post of the prosthetic valve.
5. The jacket of claim 4 , wherein the post cover portion is atraumatic.
6. The jacket of claim 1 , wherein the first portion includes first interfaces and the second portion includes second interfaces, the first and second interfaces being configured to join the first and second portions together.
7. The jacket of claim 6 , wherein the first interfaces and the second interfaces are operable to snap together to join the first portion to the second portion.
8. The jacket of claim 1 , wherein the first portion is a tissue ingrowth boundary.
9. The jacket of claim 1 , wherein the first portion includes a fillet operable to limit tissue ingrowth beyond the fillet.
10. The jacket of claim 9 , wherein the first portion includes an inflow edge and an outflow edge, a distance between the inflow and outflow edges defining the first height, the outflow edge extending generally parallel to the inflow edge.
11. The jacket of claim 10 , wherein the fillet defines a transition between the jacket and a leaflet of the prosthetic valve.
12. The jacket of claim 1 , wherein the first portion includes a flange element projecting at least partially radially outward.
13. The jacket of claim 1 , wherein the first and second portions are formed from different materials.
14. The jacket of claim 13 , wherein the first portion is formed of a relatively more flexible material as compared to the material of the second portion.
15. A jacket for a prosthetic valve comprising a commissure post and including an inflow side and an outflow side, the jacket comprising:
a first portion operable to be coupled to the outflow side of the prosthetic valve, the first portion having a first height; and
a second portion operable to be coupled to the inflow side of the prosthetic valve, the second portion having a second height,
wherein the first portion includes first interfaces and the second portion includes second interfaces, the first and second interfaces being configured to join the first and second portions together, and
wherein the first and second interfaces form a post cover portion operable to cover the commissure post of the prosthetic valve.
16. A jacket for a prosthetic valve comprising a frame and including an inflow side and an outflow side, the jacket comprising:
a first portion operable to be coupled to the outflow side of the prosthetic valve, wherein the first portion has a first height, the first portion includes a fillet operable to limit tissue ingrowth beyond the fillet, and the fillet extends radially inwardly; and
a second portion operable to be coupled to the inflow side of the prosthetic valve, the second portion has a second height,
wherein the first portion and the second portion are operable to be coupled together about the frame of the prosthetic valve.
17. The jacket of claim 16 , wherein the fillet extends one to three millimeters radially inward.
18. The jacket of claim 17 , wherein the fillet extends inwardly a first amount at a first angular position and extends inwardly by a second amount at a second angular position.
