Abstract

Valve retainers and delivery systems with valve retainers are disclosed. In certain embodiments, a portion of the valve retainer can rotate about a central axis of the delivery system relative to a different portion of the valve retainer. In certain embodiments, a first portion of the valve retainer can include a plurality of first orientation markings. In certain embodiments, a second portion of the valve retainer can include a second orientation marking, which can be aligned with a first orientation marking on the first portion of the valve retainer.

Claims

1. A delivery system for a prosthetic valve, the delivery system comprising:

a valve retainer comprising;

a first portion comprising a plurality of first orientation markings; and

a second portion comprising;

a second orientation marking; and

a plurality of attachment locations,

wherein the second portion of the valve retainer is rotatable about a central axis of the delivery system relative to the first portion of the valve retainer.

2. The delivery system of claim 1, further comprising an inner shaft and an outer sheath.

3. The delivery system of claim 1, wherein the first orientation markings and the second orientation marking are lines parallel to the central axis of the delivery system.

4. The delivery system of claim 1, wherein the first and second orientation markings are etched into an exterior surface of the first and second portions of the valve retainer.

5. The delivery system of claim 1, wherein the first orientation markings comprise a line and a numerical value.

6. The delivery system of claim 1, wherein the first portion of the valve retainer comprises nine orientation markings.

7. The delivery system of claim 1, further comprising a valve support located adjacent to the second portion of the valve retainer.

8. The delivery system of claim 7, wherein the valve support comprises a first end having a first diameter and a second end having a second diameter, wherein the second diameter is smaller than the first diameter.

9. The delivery system of claim 7, wherein the valve support is connected to the second portion of the valve retainer, and wherein the valve support can be rotated about the central axis of the delivery system to lock the second portion and first portion of the valve retainer together.

10. The delivery system of claim 1, wherein the second orientation marking is aligned with one of the plurality of attachment locations.

11. The delivery system of claim 10, wherein an attachment member of a heart valve prosthesis is attached to the slot aligned with the second orientation marking.

12. The delivery system of claim 1, wherein the second portion of the valve retainer further comprises a groove.

13. The delivery system of claim 1, wherein the second portion can lock in place when the second orientation marking is aligned with one of the first orientation markings.

14. A valve retainer comprising:

a first portion comprising a plurality of first orientation markings; and

a second portion comprising;

a second orientation marking; and

a plurality of attachment locations,

wherein the second portion of the valve retainer is rotatable about a central axis of the valve retainer relative to the first portion of the valve retainer.

15. A valve retainer comprising:

a plurality of attachment locations; and

an exterior surface;

wherein each attachment location is identified by an orientation marking on the exterior surface of the valve retainer.

16. The valve retainer of claim 15, comprising nine attachment locations, wherein the orientation marking for each attachment location comprises a numerical value.

17. The valve retainer of claim 15, wherein the attachment locations are equally spaced around the valve retainer.

18. A method of loading a prosthetic valve onto a delivery system comprising:

rotating a second portion of a valve retainer to align a second orientation marking on the second portion of the valve retainer with one of a plurality of first orientation markings on a first portion of the valve retainer; and

attaching the prosthetic valve to the second portion of the valve retainer.

19. The method of claim 18, further comprising rotating a valve support attached to the second portion of the valve retainer to lock the second portion and first portion of the valve retainer together.

20. The method of claim 18, further comprising using medical imaging of a heart to determine which of the first orientation markings on the first portion of the valve retainer with which to align the second orientation marking on the second portion of the valve retainer.

21. The method of claim 18, wherein attaching the prosthetic valve comprises attaching an attachment member on the prosthetic valve at an attachment location on the second portion of the valve retainer.

22. The method of claim 21, wherein the attachment location is aligned with the second orientation marking on the second portion of the valve retainer.
