Abstract

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.

First claim

What is claimed is:

1 . A jacket for a prosthetic valve 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 for form a protective covering around the prosthetic heart 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 be secured together about a frame of the prosthetic valve.

4 . The jacket of claim 3 , wherein the first and second portions are operable to interface between a sewing cuff and the frame of the prosthetic valve.

5 . The jacket of claim 1 , wherein the first portion includes a post cover portion operable to cover a commissure post of the prosthetic valve.

6 . The jacket of claim 5 , wherein the post cover portion is atraumatic.

7 . 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.

8 . The jacket of claim 7 , wherein the first and second interfaces form a post cover portion operable to cover a commissure post of the prosthetic valve.

9 . The jacket of claim 7 , wherein the first interfaces and the second interfaces are operable to snap together to join the first portion to the second portion.

10 . The jacket of claim 1 , wherein the first portion is a tissue ingrowth boundary.

11 . The jacket of claim 1 , wherein the first portion includes a fillet operable to limit tissue ingrowth beyond the fillet.

12 . The jacket of claim 11 , wherein the fillet extends radially inwardly.

13 . The jacket of claim 12 , wherein the fillet extends one to three millimeters radially inward.

14 . The jacket of claim 13 , 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.

15 . The jacket of claim 11 , the first portion includes an outflow edge and the second portion includes an inflow edge defining the first height, the outflow edge extending generally parallel to the inflow edge.

16 . The jacket of claim 15 , wherein the fillet defines a transition between the inflow edge of the second portion.

17 . The jacket of claim 16 , wherein the fillet is positioned between the inflow edge of the second portion and a transition region defined where the jacket terminates into an inflow side the prosthetic valve.

18 . The jacket of claim 1 , wherein the first portion includes a flange element projecting at least partially radially outward.

19 . The jacket of claim 1 , wherein the first and second portions are formed from different materials

20 . The jacket of claim 19 , wherein the first portion is formed of a relatively more flexible material as compared to the material of the second portion.
