Abstract

We disclose an implantable prosthetic heart valve, comprising: a valve body comprising an orifice member, wherein the orifice member comprises an external groove; a sewing cuff; a sewing cuff retaining member seated within the external groove of the orifice member and coupling the sewing cuff to the orifice member; a tubular vascular graft; and a graft retaining member seated within the external groove of the orifice member and coupling the tubular vascular graft to the orifice member.

Claims

1. An implantable prosthetic heart valve, comprising:

a valve body comprising an orifice member, wherein the orifice member comprises a least one external groove;

a tubular vascular graft; and

a graft retaining member seated within the external groove of the orifice member and coupling the tubular vascular graft to the orifice member.

2. The implantable prosthetic heart valve of claim 1, further comprising a sewing cuff, and a sewing cuff retaining member seated within an external groove of the orifice member and coupling the sewing cuff to the orifice member.

3. The implantable prosthetic heart valve of claim 1, wherein the sewing cuff retaining member is a solid ring.

4. The implantable prosthetic heart valve of claim 1, wherein the sewing cuff retaining member is a spring.

5. The implantable prosthetic heart valve of claim 1, wherein the graft retaining member is a solid ring.

6. The implantable prosthetic heart valve of claim 1, wherein the graft retaining member is a spring.

7. The implantable prosthetic heart valve of claim 1, comprising one external groove, wherein the external groove has an upstream shoulder and a downstream shoulder and the graft retaining member is seated between the sewing cuff retaining member and the upstream shoulder of the external groove.

8. The implantable prosthetic heart valve of claim 1, comprising one external groove, wherein the external groove has an upstream shoulder and a downstream shoulder and the graft retaining member is seated between the sewing cuff retaining member and the downstream shoulder of the external groove.

9. The implantable prosthetic heart valve of claim 1, comprising two external grooves, wherein graft retaining member is seated in a first external groove and the sewing cuff retaining member is seated in a second external groove.

10. An implantable prosthetic heart valve, comprising:

a means for defining a blood flow path;

a means for substituting for a diseased vascular segment; and

a means for coupling the tubular vascular graft to the means for defining a blood flow path.

11. The implantable prosthetic heart valve of claim 10, further comprising a means for attaching the implantable prosthetic heart valve to the interior wall of a blood vessel, and a means for coupling the attaching means to the means for defining a blood flow path.

12. A method of attaching a tubular vascular graft to a valve body comprising an orifice member, wherein the orifice member comprises at least one external groove, the method comprising:

coupling the tubular vascular graft to the orifice member with a graft retaining member seated within the external groove of the orifice member.

13. A method of implanting a prosthetic heart valve comprising a tubular vascular graft into a patient, comprising:

removing a prior heart valve and adjacent arterial section from the vasculature of the patient;

placing the prosthetic heart valve into the position formerly occupied by the removed prior heart valve, wherein the prosthetic heart valve comprises a valve body comprising an orifice member, wherein the orifice member comprises at least one external groove;

a sewing cuff;

a sewing cuff retaining member seated within an external groove of the orifice member and coupling the sewing cuff to the orifice member;

a tubular vascular graft; and

a graft retaining member seated within an external groove of the orifice member and coupling the tubular vascular graft to the orifice member; and

attaching the prosthetic heart valve and tubular vascular graft to the vasculature of the patient.

14. The method of claim 13, wherein the position formerly occupied by the removed prior heart valve is the aortic valve position, and the adjacent arterial section is the sinus valsalva.
