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/non-collapsible prosthetic heart valve member having a sewing ring on an inflow end;

an expandable anchoring member sized to contact a heart valve annulus in an expanded state and being connected to the sewing ring.

2. The heart valve of claim 1, wherein the anchoring member comprises a tubular structure having connectors adapted to engage the sewing ring.

3. The heart valve of claim 2, wherein the connectors comprise prongs that change shape and engage the base ring.

4. The heart valve of claim 2, wherein the prongs are shaped to wrap around the base ring.

5. The heart valve of claim 1, wherein the anchoring member comprises a stent having a wider outflow end than an inflow end, and wherein the valve sewing ring is sized to fit within the outflow end of the stent.

6. The heart valve of claim 1, wherein the anchoring member comprises a tubular structure having a suture-permeable fixation ring attached thereto, wherein the valve member connects to the anchoring member via sutures looped between the valve sewing ring and the fixation ring.
