Abstract

A prosthetic heart valve system including a prosthetic heart valve and a deflection device. The deflection device includes a line and a connector assembly including a tensioning component. The line interconnects and passes through free ends of stent posts associated with the heart valve, and is further connected to the tensioning component. The tensioning component is transitionable to a tensioning state in which the line is tensioned to inwardly deflect the stent posts. In this regard, the tensioning component is self-locking relative to the line in the tensioning state, and an entirety of the line extending distal the tensioning device does not extend beyond a stent portion of the heart valve opposite the stent posts. In a preferred embodiment, a holder body is further included, coupled to the heart valve apart from the deflection device.

Claims

1. A prosthetic heart valve and a holder comprising:

a prosthetic heart valve including a stent and a plurality of stent posts extending from the stent, each of the stent posts defining a free end, and leaflets operatively associated with structure of the stent and stent posts;

a holder including a holder body that is releasably coupled to the prosthetic heart valve by a first line so as to permit manipulation of the prosthetic heart valve by way of the holder; and

a deflection device including a tensioning component that is also releasably coupled to the prosthetic heart valve, the tensioning component also being transitional relative to the prosthetic heart valve and with respect to a second line for deflecting at least one free end of a stent post by engagement of the tensioning component with the second line, wherein the coupling of the holder body permits the holder to be uncoupled from and moved away from the prosthetic heart valve without uncoupling the tensioning component of the deflection device from the prosthetic heart valve.

2. The prosthetic heart valve and holder of claim 1, further comprising:

a first line coupling the holder body to the prosthetic heart valve; and

a second line coupling the tensioning component to the prosthetic heart valve.

3. The prosthetic heart valve and holder of claim 1 wherein the tissue material is pericardium.

4. A prosthetic heart valve and a holder comprising:

a prosthetic heart valve including a stent and a plurality of stent posts extending from the stent, each of the stent posts defining a free end, and leaflets operatively associated with structure of the stent and stent posts;

a holder including a holder body that is releasably coupled to the prosthetic heart valve by a first line so as to permit manipulation of the prosthetic heart valve by way of the holder; and

a deflection device including a tensioning component that is also releasably coupled to the prosthetic heart valve, the tensioning component also being transitional relative to the prosthetic heart valve and with respect to a second line for deflecting at least one free end of a stent post by engagement of the tensioning component with the second line, wherein the coupling between the holder and heart valve permits uncoupling and movement of the holder body away from the prosthetic heart valve, while the tensioning component remains coupled to the prosthetic heart valve with at least the one free end of a stent post being deflected by the tensioning component.

5. The prosthetic heart valve and holder of claim 4, wherein the holder body and the tensioning device are separately coupled to the prosthetic heart valve.

6. The prosthetic heart valve and holder of claim 5, wherein the holder body forms a central passage, and further wherein upon final assembly, the tensioning component is accessible via the central passage.

7. The prosthetic heart valve and holder of claim 6, wherein the prosthetic heart valve is a prosthetic mitral valve.

8. The prosthetic heart valve and holder of claim 6, wherein the prosthetic heart valve is a prosthetic aortic valve.

9. A prosthetic heart valve and a holder comprising:

a prosthetic heart valve including a stent and a plurality of stent posts extending from the stent, each of the stent posts defining a free end, and leaflets operatively associated with structure of the stent and stent posts;

a holder including a holder body that is releasably coupled to the prosthetic heart valve by a first line so as to permit manipulation of the prosthetic heart valve by way of the holder; and

a deflection device including a tensioning component that is also releasably coupled to the prosthetic heart valve, the tensioning component also being transitional relative to the prosthetic heart valve and with respect to a second line for deflecting at least one free end of a stent post by engagement of the tensioning component with the second line, wherein the coupling of the holder body permits the holder to be uncoupled from and moved away from the prosthetic heart valve without uncoupling the tensioning component of the deflection device from the prosthetic heart valve, and further wherein the tensioning component is releasably coupled with the holder body for manipulation as a unit together and for independent manipulation from one another.
