Abstract

Claims (49)

1 . A prosthetic heart valve for implantation in a native valve of a heart, the prosthetic heart valve comprising:

a plurality of prosthetic valve leaflets positioned within a flow channel of the prosthetic heart valve;

an expandable and compressible inner frame supporting the plurality of prosthetic valve leaflets;

an expandable and compressible sealing body for sealing with a portion of the heart, the sealing body positioned radially outward of the inner frame, wherein at least a portion of the sealing body includes a plurality of friction bodies along an outer surface thereof; and

a plurality of ventricular anchors extending from an outflow end of the prosthetic heart valve for capturing leaflets of the native valve between the ventricular anchors and the outer surface of the sealing body;

wherein:

the friction bodies contact the captured leaflets of the native valve for enhancing securement of the prosthetic heart valve in the native valve; and

each of the friction bodies includes a fabric having a honeycomb weave pattern and wherein the honeycomb weave pattern is formed by fibers that have been heat treated to increase a thickness of the honeycomb weave pattern.

2 . The prosthetic heart valve of claim 1 , wherein the friction bodies include a protrusion coupled to a wire.

3 . The prosthetic heart valve of claim 1 , wherein the fabric is a first fabric and the prosthetic heart valve further comprises a second fabric coupled to the plurality of ventricular anchors, wherein the second fabric has a second honeycomb weave pattern formed by wavy fibers that have been heat treated to increase a thickness of the second honeycomb weave pattern.

4 . The prosthetic heart valve of claim 1 , wherein the sealing body comprises a skirt and wherein the outer surface of the sealing body is the outer surface of the skirt.

5 . The prosthetic heart valve of claim 4 , wherein the friction bodies are embedded in the skirt.

6 . The prosthetic heart valve of claim 4 , wherein the friction bodies include protrusions extending from the outer surface of the skirt.

7 . The prosthetic heart valve of claim 4 , wherein the sealing body is a metallic outer frame coupled to the inner frame and wherein the skirt is wrapped around the outer frame.

8 . The prosthetic heart valve of claim 7 , wherein the outer frame is coupled to the inner frame at an inflow end of the prosthetic heart valve.

9 . The prosthetic heart valve of claim 1 , wherein each of the plurality of ventricular anchors has a hook shape for hooking around a leaflet of the native valve.

10 . The prosthetic heart valve of claim 1 , wherein each of the friction bodies is positioned on the outer surface of the sealing body at a location opposed to one of the ventricular anchors.

11 . The prosthetic heart valve of claim 1 , wherein the prosthetic heart valve is sized for replacing a native mitral valve or a native tricuspid valve.

12 . A prosthetic heart valve for implantation in a native valve of a heart, the prosthetic heart valve comprising:

a plurality of prosthetic valve leaflets positioned within a flow channel of the prosthetic heart valve;

a frame supporting the plurality of prosthetic valve leaflets;

an anchor coupled to the frame and adapted to anchor the frame to the native valve; and

a pad coupled to the anchor, the pad adapted to cushion the anchor against a portion of the native valve and including a fabric having a honeycomb weave pattern,

wherein the honeycomb weave pattern is formed by fibers that are wavy and have been heat treated to increase a thickness of the honeycomb weave pattern.

13 . The prosthetic heart valve of claim 12 , wherein the anchor has a hook shape for hooking around a leaflet of the native valve.

14 . The prosthetic heart valve of claim 12 , wherein the anchor includes an elongate arm having a length and extending to a tip, and the pad covers the tip of the arm or extends along the length of the elongate arm.

15 . A prosthetic heart valve for implantation in a native valve of a heart, the prosthetic heart valve comprising:

a plurality of prosthetic valve leaflets positioned within a flow channel of the prosthetic heart valve;

an expandable and compressible inner frame supporting the plurality of prosthetic valve leaflets;

an expandable and compressible sealing body for sealing with a portion of the heart, the sealing body positioned radially outward of the inner frame, wherein at least a portion of the sealing body includes a plurality of friction bodies along an outer surface thereof;

a plurality of ventricular anchors extending from an outflow end of the prosthetic heart valve for capturing leaflets of the native valve between the ventricular anchors and the outer surface of the sealing body; and

for each of the ventricular anchors, a fabric coupled to the anchor, wherein the fabric has a honeycomb weave pattern formed by wavy fibers that have been heat treated to increase a thickness of the honeycomb weave pattern;

wherein the friction bodies contact the captured leaflets of the native valve for enhancing securement of the prosthetic heart valve in the native valve.

16 . A prosthetic heart valve for implantation in a native valve of a heart, the prosthetic heart valve comprising:

a plurality of prosthetic valve leaflets positioned within a flow channel of the prosthetic heart valve;

an expandable and compressible inner frame supporting the plurality of prosthetic valve leaflets;
