Abstract

Valve holders and introducers for delivering a prosthetic heart valve to an implant site are in various embodiments configured to facilitate insertion of prosthetic valves through small incisions or access sites on a patient's body. The valve holders can also be configured to reduce or eliminate the occurrence of suture looping or other damage to the prosthetic valve during implantation. A valve holder according to embodiments of the invention includes features that reduce or eliminate mistakes during implantation of the prosthetic valves, such as a removable activator dial and a removable handle that prevent implantation of the valve prior to proper deployment or adjustment of the holder. An introducer is provided which can facilitate passing of a prosthetic valve between adjacent ribs of a patient. Valve holders and introducers according to the various embodiments can be used in minimally invasive procedures, such as thoracotomy procedures.

First claim

What is claimed is:

1. A valve holder for holding and implanting a prosthetic heart valve comprising a frame and a plurality of flexible leaflets, the valve holder comprising:
a body for holding the prosthetic heart valve, the body having a top surface, a bottom surface, and a central axis extending between the top and bottom surfaces;
a rotor positioned in the body, wherein when the prosthetic heart valve is coupled to the body, the rotor is rotatable around the central axis of the body to adjust the prosthetic heart valve to a delivery position; and
a latch having an opening couplable with a handle, and through which an activator is couplable to the rotor for rotating the rotor around the central axis of the body; further comprising the handle, wherein the opening of the latch comprises a threaded portion matable with a threaded portion of the handle.

2. The valve holder of claim 1 , wherein the threaded portion of the handle is at a tip of the handle.

3. The valve holder of claim 2 , wherein the opening of the latch comprises an unthreaded portion followed by the threaded portion such that when the handle is inserted into the latch, the tip passes through the unthreaded portion before passing into the threaded portion.

4. The valve holder of claim 1 , wherein the rotor comprises an opening configured to receive the activator, and wherein the opening in the rotor and the opening in the latch are coaxial with the central axis of the body.

5. The valve holder of claim 4 , further comprising the activator, wherein the activator is separable from and connectable to the rotor for rotating the rotor around the central axis of the body.

6. The valve holder of claim 5 , further comprising a guide coupled to the body for facilitating coupling of the activator to the rotor when the activator is at a first rotational orientation relative to the rotor.

7. The valve holder of claim 6 , wherein the guide further facilitates decoupling of the activator from the rotor when the activator is at a second rotational orientation different from the first rotational orientation relative to the rotor.

8. The valve holder of claim 7 , wherein the activator is limited to rotating the rotor less than one full turn around the central axis of the body between the first rotational orientation and the second rotational orientation.

9. The valve holder of claim 7 , wherein when the activator is coupled to the rotor at the second rotational orientation, the rotor is restricted from rotating in either rotational direction.

10. The valve holder of claim 6 , wherein the guide is positioned between the latch and the rotor, and wherein the guide defines an opening to permit the activator to access the rotor.

11. The valve holder of claim 5 , wherein the opening of the latch comprises an engagement portion configured to engage the handle, and wherein the activator is connectable to the rotor without engaging the engagement portion of the latch.

12. The valve holder of claim 1 , further comprising the handle and the activator, wherein when the handle is received in the opening in the latch, the handle blocks the activator from being connected to the rotor.

13. The valve holder of claim 1 , further comprising the handle and the activator, wherein the activator is connectable to the rotor for rotating the rotor around the central axis of the body.

14. A system comprising:
the valve holder of claim 1 ;
the prosthetic heart valve; and
the activator, wherein the activator is connectable to the rotor at the top surface of the body and wherein the prosthetic heart valve is connectable to the bottom surface of the body.

15. A system comprising:
the valve holder of claim 1 ;
the prosthetic heart valve; and
the handle, wherein when the prosthetic heart valve is connected to the bottom surface of the body and the handle is connected to the latch, the top surface of the body faces the handle.

16. The valve holder of claim 1 , wherein the rotor is rotatable relative to the latch.

17. The valve holder of claim 1 , wherein the opening of the latch comprises an engagement portion configured to engage the handle.

18. The valve holder of claim 17 , wherein the engagement portion comprises a thread.

19. The valve holder of claim 1 , wherein the rotor is rotatable around the central axis of the body in a first direction and not rotatable in a second direction opposite the first direction.
