Abstract

A prosthetic heart comprising a tube having proximal and distal ends, and a central lumen, a tubular frame having proximal and distal ends, and a central lumen, the tubular frame, comprising a plurality of radially-extending members, being disposed on an outside wall of the tube, the distal end of the tube being everted around the distal end of the tubular frame and extending proximally along the tubular frame and over the radially-extending members, and a valve member attached to the tube.

Claims

1. A prosthetic heart valve comprising:

a tube defining a proximal end, a distal end, and a central lumen;

a tubular frame being disposed on an outside wall of the tube, the tubular frame comprising;

a plurality of longitudinally-extending members, each having a hook at a distal end thereof; and

at least one laterally-extending member fixed to the longitudinally-extending members, the laterally-extending member extending circumferentially relative to the longitudinally-extending members;

the distal end of the tube being everted around the distal end of the tubular frame and extending proximally along the tubular frame and over the hooks to be engaged thereby;

wherein the distal end of the tube comprises a radially-extending flange;

wherein one laterally-extending member is at least partially positioned outside of the tube; and

a valve member attached to the tube.

2. The prosthetic heart valve of claim 1 wherein the hooks are configured to secure the tubular frame to tissue.

3. The prosthetic heart valve of claim 1 wherein the at least one laterally-extending member comprises a circular hoop configuration.

4. The prosthetic heart valve of claim 1 wherein the at least one laterally-extending member comprises a serpentine configuration.

5. The prosthetic heart valve of claim 1 wherein the distal end of the tube is flared outwardly.

6. A prosthetic heart valve comprising:

a tube defining a proximal end, a distal end, and a central lumen;

a tubular frame defining a proximal end, a distal end, and a central lumen, the tubular frame being disposed on an outside wall of the tube the tubular frame comprising;

a plurality of longitudinally-extending members, each having a hook at a distal end thereof;

wherein the proximal end of each longitudinally-extending member comprises a fixation element for securing the tubular frame to tissue; and

at least one laterally-extending member fixed to the longitudinally-extending members, the laterally-extending member extending circumferentially relative to the longitudinally-extending members;

the distal end of the tube being everted around the distal end of the tubular frame and extending proximally along the tubular frame and over the hooks to be engaged thereby;

wherein one laterally-extending member is at least partially positioned outside of the tube; and

a valve member attached to the tube.

7. The prosthetic heart valve of claim 6 wherein the fixation element is configured to be bent radially outward to engage tissue.

8. The prosthetic heart valve of claim 6 further comprising a restraining device, wherein the fixation element is adapted to be deployed by removing the restraining device, whereby the fixation element automatically deploys to engage tissue.

9. A prosthetic heart valve comprising:

a tube defining a proximal end, a distal end, and a central lumen;

a tubular frame defining a proximal end, a distal end, and a central lumen, the tubular frame being disposed on an outside wall of the tube, the tubular frame further comprising a plurality of radially-extending members;

wherein the tubular frame further comprises a plurality of longitudinally-extending members having a distal end and a proximal end;

wherein the proximal end of each longitudinally-extending member is positioned outside of the everted tube;

wherein the tubular frame further comprises at least one laterally-extending member fixed to the longitudinally-extending members, the laterally-extending member extending circumferentially relative to the longitudinally-extending members;

wherein the proximal end of each longitudinally-extending member comprises a fixation element for securing the tubular frame to tissue;

the distal end of the tube being everted around the distal end of the tubular frame and extending proximally along the tubular frame and over the radially-extending members;

wherein the tubular frame is at least partially positioned outside of the everted tube; and

a valve member attached to the tube.

10. The prosthetic heart valve of claim 9 wherein the at least one laterally-extending member comprises a circular hoop configuration.

11. The prosthetic heart valve of claim 9 wherein the at least one laterally-extending member comprises a serpentine configuration.

12. The prosthetic heart valve of claim 9 wherein the fixation element is configured to be bent radially outward to engage tissue.

13. The prosthetic heart valve of claim 9 further comprising a restraining device, wherein the fixation element is adapted to be deployed by removing the restraining device, whereby the fixation element automatically deploys to engage tissue.

14. The prosthetic heart valve of claim 9 wherein each radially-extending member comprises a hook configured to secure the tubular frame to tissue.

15. The prosthetic heart valve of claim 9 wherein the distal end of the tube is flared outwardly.

16. The prosthetic heart valve of claim 9 wherein the distal end of the tube comprises a radially-extending flange.
