Abstract

A biologically implantable prosthesis is disclosed. The prosthesis can have a circumferentially expandable wall and elements that prevent the wall from collapsing once the wall is expanded. Methods of making and using the prosthesis are also disclosed.

Claims

1. A biologically implantable system for a heart valve comprising:

a first prosthesis comprising tissue, and

a second prosthesis comprising an engagement element, wherein the engagement element is configured to engage the first prosthesis in one or more parallel planes.

2. The system of claim 1, wherein the first prosthesis comprises a tissue leaflet.

3. A biologically implantable system for a heart valve comprising:

a first prosthesis comprising tissue, and

a second prosthesis having a longitudinal axis, the second prosthesis comprising an engagement element configured to self-engage the first prosthesis.

4. The system of claim 3, wherein the first prosthesis comprises a tissue leaflet.

5. The system of claim 3, wherein the engagement element is configured to self-engage the first prosthesis when the first prosthesis is moved relative to the second prosthesis parallel to the longitudinal axis.

6. The system of claim 3, wherein the second prosthesis comprises a circumferentially expandable wall.

7. A biologically implantable first prosthesis for a heart valve comprising:

a first prosthesis comprising tissue, and an engagement element configured to self-engage a second prosthesis.

8. The prosthesis of claim 7, wherein the first prosthesis comprises a tissue leaflet.

9. The prosthesis of claim 7, wherein the engagement element is configured to self-engage the second prosthesis when the first prosthesis is moved relative to the second prosthesis parallel to a longitudinal axis of the second prosthesis.
