Abstract

A prosthetic heart valve for replacing a defective aortic valve includes a self-expandable annular frame made of shape-memory material. A one-way valve structure is disposed within an interior of the frame. The frame includes a plurality of posts projecting axially from an outflow end portion of the frame, wherein each of the posts includes an axial post portion and a terminal post portion. The terminal post portions have greater circumferential dimensions than the axial post portions. The terminal post portions are preferably formed with concave inner surfaces and convex outer surfaces for conforming to the shape of a delivery catheter. Each of the posts is shaped for placement within a corresponding recess along a distal end portion of the delivery catheter for ensuring that the prosthetic heart valve remains coupled to the delivery catheter while the prosthetic heart valve is expanded within the defective aortic valve.

Dependent claims

A prosthetic heart valve comprising:

an annular frame made of shape-memory material and being radially collapsible and self-expandable, the frame having an inflow end portion and an outflow end portion;
and
a valve structure disposed within an interior of the frame that allows blood flow axially through the prosthetic heart valve from the inflow end portion toward the outflow end portion;
wherein the frame comprises a plurality of posts projecting axially at the outflow end portion of the frame;
wherein each of the posts comprises an axial post portion extending from the outflow end portion of the frame and a terminal post portion at an end of the axial post portion;
wherein the terminal post portion has a greater circumferential dimension than the axial post portion;
wherein the terminal post portions are circumferentially curved and have a concave radially facing inner surface and a convex radially facing outer surface;
wherein when the frame is radially expanded, the frame has an inflow end diameter at the inflow end portion, an outflow end diameter at the outflow end portion, a first intermediate diameter at a first intermediate portion that is between the inflow end portion and the outflow end portion, and a second intermediate diameter at a second intermediate portion that is between the first intermediate portion and the outflow end portion;
wherein the first intermediate diameter is smaller than the inflow end diameter and the second intermediate diameter;
and
wherein the outflow end diameter is smaller than the second intermediate diameter.
