Abstract

A support device for implanting stentless valve prostheses, such as biological heart valves, includes a hub and a plurality of support portions for supporting the stentless valve prosthesis. The hub defines a manipulation axis for the device and is flexibly connected to the support portions to allow displacing the manipulation axis for the device between the support portions.

Claims

1. A support device for implanting stentless valve prostheses, the device including:

a hub defining a manipulation axis for the device, and

a plurality of support portions for supporting a stentless valve prosthesis, wherein the hub is pivotably connected to the support portions via a flexible joint to allow pivotably displacing the manipulation axis between the support portions.

2. The device of claim 1, further including a plurality of formations extending around the hub with respective support portions for supporting the stentless valve prosthesis.

3. The device of claim 1, further including a plurality of formations extending radially from the hub with respective distal support portions for supporting the stentless valve prosthesis.

4. The device of claim 2, wherein the formations extending around the hub have a concave shape with a concavity directed towards the hub.

5. The device of claim 2, wherein flexible connection of the hub to the support portions is elastic to bias the hub centrally of the support portions.

6. The device of claim 2, wherein the support portions have a wire-like or ribbon-like structure.

7. The device of claim 2, wherein the support portions have passageways for fixing means of the prosthesis to the device.

8. The device of claim 2, further including a restraining element to restrain the device to a radially contracted condition.

9. The device of claim 8, wherein the restraining element restrains displacement of the manipulation axis for the device between the support portions.

10. The device of claim 2, further including protective elements for the leaflets of the prosthesis.

11. The device of claim 10, wherein the protective elements are carried by support elements extending from the hub.

12. The device of claim 2, wherein the support portions support the commissures of the prosthesis.

13. A kit for implanting a valve prosthesis, the kit comprising:

a support device including;

a hub defining a manipulation axis for the device, and

a plurality of support portions for supporting a stentless valve prosthesis, wherein the hub is pivotably connected to the support portions via a flexible joint to allow pivotably displacing the manipulation axis between the support portions; and

a stentless valve prosthesis, the prosthesis mounted on the support device with the prosthesis supported by the support portions of the support device.
