Cardiac repair prosthesis sets and methods
Cardiac repair prostheses, sets, and methods for implanting in an aorta are disclosed. Cardiac repair prosthesis sets can include a radially expandable support supporting a unidirectional valve that is configured for implantation into the aortic valve region of a patient and a second radially expandable support for a substantially blood impervious stent having a size and shape for implantation into the ascending aorta of said patient where the unidirectional valve and stent are configured for integration within the patient by at least one joining element. Cardiac repair prostheses can include a radially expandable support supporting a unidirectional valve configured for implantation into the aortic valve region of a patient and a second radially expandable support for a substantially blood impervious stent having a size and shape for implantation into the ascending aorta of said patient where the unidirectional valve and stent are joined by at least one joining element.
1. A cardiac repair prosthesis comprising:
a first radially expandable scaffolding comprising a unidirectional valve configured for implantation into the aortic valve region of a patient; and
a second radially expandable scaffolding having a size and shape for implantation into the ascending aorta of said patient;
the first radially expandable scaffolding and the second radially expandable scaffolding being joined by at least one joining element, and,
at least one portion of the first radially expandable scaffolding having a diameter that is different from a diameter of at least one portion the second radially expandable scaffolding.
2. The cardiac repair prosthesis of claim 1 wherein the at least one joining element comprises a suture.
3. The cardiac repair prosthesis of claim 1 , wherein the at least one joining element comprises a clip.
4. The cardiac repair prosthesis of claim 3 , wherein the clip has a hinge and locking mechanism.
5. The cardiac repair prosthesis of claim 1 , wherein the unidirectional valve comprises one or more leaflets.
6. The cardiac repair prosthesis of claim 1 , wherein the unidirectional valve comprises two or three leaflets.
7. The cardiac repair prosthesis of claim 5 , wherein the leaflets comprise a biological material.
8. The cardiac repair prosthesis of claim 5 , wherein the leaflets comprise a synthetic material.
9. The cardiac repair prosthesis of claim 1 , wherein the first radially expandable scaffolding is partially covered by a material that is substantially impervious to blood.
10. The cardiac repair prosthesis of claim 1 , wherein the first radially expandable scaffolding is configured for implantation in the aortic annulus of a patient.
11. The cardiac repair prosthesis of claim 1 , wherein a longitudinal end of the first radially expandable scaffolding is joined to a longitudinal end of the second radially expandable scaffolding by the at least one joining element.
12. The cardiac repair prosthesis of claim 1 , wherein the second radially expandable scaffolding is at least partially covered by a material that is substantially impervious to blood.
13. The cardiac repair prosthesis of claim 1 , wherein the second radially expandable scaffolding includes a first longitudinal end and a second longitudinal end, wherein a diameter of the second radially expandable scaffolding at the first longitudinal end is different than a diameter of the second radially expandable scaffolding at the second longitudinal end.
14. The cardiac repair prosthesis according to claim 1 , wherein at least a portion of the first radially expandable scaffolding has a diameter that is less than a diameter of at least one portion the second radially expandable scaffolding.
