Abstract
An implantable prosthetic valve can include a radially expandable and collapsible annular frame comprising an inflow end and an outflow end. The frame can have a plurality of struts forming a plurality of cells, wherein each of the plurality of cells defines an opening in the frame. A leaflet structure can be positioned within the frame and secured thereto. A plurality of sealing members can be positioned within the openings of a plurality of the cells of the frame and secured thereto. Each of the plurality of sealing members can be positioned within a respective one of the openings.
Claims20
An implantable prosthetic valve comprising:
- an annular frame comprising an inflow end, an outflow end, and a plurality of struts forming a plurality of cells, wherein each of the cells defines an opening in the frame, and wherein the frame is radially collapsible and expandable between a radially collapsed configuration and a radially expanded configuration;
- a leaflet structure positioned within the frame and secured thereto;
- and
- a plurality of sealing members positioned within the openings of a plurality of the cells of the frame and secured thereto, wherein each of the sealing members is positioned within a respective one of the openings.
An assembly for implanting a prosthetic heart valve, comprising:
- a delivery apparatus comprising an elongate shaft;
- and
- a prosthetic heart valve, comprising:
- an annular frame comprising an inflow end, an outflow end, and a plurality of struts forming a plurality of cells, wherein each of the cells defines an opening in the frame, and wherein the frame is radially collapsible and expandable between a radially collapsed configuration and a radially expanded configuration;
- a leaflet structure positioned within the frame and secured thereto;
- and
- a plurality of sealing members positioned within the openings of a plurality of the cells of the frame and secured thereto, wherein each of the sealing members is positioned within a respective one of the openings.
- wherein the prosthetic heart valve is coupled to the shaft of the delivery apparatus.
A method of implanting a prosthetic heart valve, comprising:
- radially compressing the prosthetic heart valve to a radially compressed configuration;
- wherein the prosthetic valve comprises:
- an annular frame comprising an inflow end, an outflow end, and a plurality of struts forming a plurality of cells, wherein each of the cells defines an opening in the frame, and wherein the frame is radially collapsible and expandable between a radially collapsed configuration and a radially expanded configuration;
- a leaflet structure positioned within the frame and secured thereto;
- and
- a plurality of sealing members positioned within the openings of a plurality of the cells of the frame and secured thereto, wherein each of the sealing members is positioned within a respective one of the openings,
- coupling the prosthetic heart valve to a distal end portion of a delivery apparatus;
- inserting the distal end portion of the delivery apparatus and the prosthetic heart valve into a patient's body;
- positioning the prosthetic heart valve adjacent a native valve of the patient's heart;
- and
- radially expanding the prosthetic heart valve so that it engages the native valve.
