Abstract

A heart valve prosthesis that can be quickly and easily implanted during a surgical procedure is provided. The prosthetic valve comprises a support structure that is deployed at a treatment site. The prosthetic valve further comprises a valve member configured to be quickly connected to the support structure. The support structure may take the form of a stent that is expanded at the site of a native valve. If desired, the native leaflets may remain and the stent may be used to hold the native valve open. In this case, the stent may be balloon expandable and configured to resist the powerful recoil force of the native leaflets. The support structure is provided with a coupling means for attachment to the valve member, thereby fixing the position of the valve member in the body. The valve member may be expandable or a non-expandable type.

Claims

1. A prosthetic heart valve comprising:

a non-expandable valve member comprising a base ring surrounding an inflow end thereof;

an expandable anchoring member sized to contact and anchor to a heart valve annulus in an expanded state, the expandable anchoring member comprising an expandable, tubular structure formed of a plurality of axial struts joined by a plurality of angled circumferential struts; and

means for coupling the non-expandable valve member to the anchoring member.

2. The prosthetic heart valve of claim 1, wherein the means for coupling comprises a plurality of sutures.

3. The prosthetic heart valve of claim 1, wherein the anchoring member comprises a suture-permeable fixation ring attached thereto, wherein the means for coupling comprises sutures looped between the base ring and the fixation ring.

4. The prosthetic heart valve of claim 3, further comprising an outer sealing ring.

5. The prosthetic heart valve of claim 1, further including an adapter sized to surround the non-expandable valve member and to engage the anchoring member, to connect the non-expandable valve member and anchoring member.

6. The prosthetic heart valve of claim 5, wherein the adapter is selected from the group consisting of:

an annular ring; and

a wireform-shaped member.

7. The prosthetic heart valve of claim 5, wherein the adapter includes a plurality of discrete connectors, and the anchoring member comprises a plurality of mating connectors spaced around a peripheral outflow end thereof, the connectors on the adapter and anchoring member being configured to engage one another by displacing the adapter toward the anchoring member.

8. The prosthetic heart valve of claim 5, wherein the adapter further includes a plurality of connectors adapted to engage and couple the adapter directly to the base ring.

9. The prosthetic heart valve of claim 1, wherein the expandable, tubular structure comprises a series of both diamond-shaped and chevron-shaped openings.
