1. A modular heart valve prosthesis, comprising:
- an independently implantable graft assembly module including a stiffening member having an axial bore extending therethrough, and having an inner surface and an outer surface a grafting member secured to said stiffening member at the outer surface thereof, and a retaining member resiliently engaging said outer surface of the stiffening member, at least a first part of said retaining member extending through said stiffening member and a valve module insertable in said graft assembly module after implantation of said graft assembly module, said valve module including a valve body having a first groove extending at least partially around an outer surface of the valve body, said valve module being selectively secured in said graft assembly module by said first part of said retaining member engaging said first groove.

Abstract
A heart valve prosthesis including a valve body having a first retainer integrally formed with an outer surface thereof. A grafting assembly is formed to include a stiffening member having an axial bore extending therethrough and a second retainer integral with a surface of the stiffening member. The valve body is mounted within the bore of the stiffening member. A retaining member engages the first and second retainers to limit axial displacement of the stiffening member relative to the valve assembly.

13. A method of implanting a heart valve, comprising the steps of:
-
forming a valve body having a first groove extending at least partially around an outer surface of the valve body;
forming a graft assembly including a stiffening member having an axial bore extending therethrough for receiving the valve body and also including a second groove in a surface thereof;
a grafting member secured to an outer surface of said stiffening member, and a retaining member in the second groove of the stiffening member,implanting said graft assembly in the cardiovascular system of a patient, inserting said valve body into said axial bore of said stiffening member of the implanted graft assembly, until said retaining member engages the first groove of the valve body to limit axial displacement of the valve body relative to the stiffening member. - View Dependent Claims (14, 15, 16, 17, 18)
