Abstract

Claims (25)

1. An implantable prosthetic device, comprising:

a radially expandable and compressible frame comprising a plurality of interconnected struts, each strut having a first end, a second end, a length extending from the first end to the second end, a radially inward facing surface, a radially outward facing surface, and two opposing longitudinal edges extending from the radially inward facing surface to the radially outward facing surface;

wherein each strut comprises a plurality of recesses including at least first and second recesses disposed on one or both of the longitudinal edges of the strut and extending into a width of the strut, and wherein the recesses are configured to retain one or more sutures and prevent the one or more sutures from sliding along the length of the strut;

wherein the first recess is located on a first longitudinal edge of the strut and the second recess is located on a second longitudinal edge of the strut; and

wherein the first and second recesses are offset from one another along the length of the strut such that when the frame is in an expanded configuration the first and second recesses are aligned with one another across a width of the strut.

2. The prosthetic device of claim 1 , wherein each recess extends radially through a thickness of the strut.

3. The prosthetic device of claim 1 , wherein each strut comprises a plurality of linear segments that are laterally offset from each other in a direction perpendicular to the lengths of the struts, wherein each linear segment comprises a plurality of recesses.

4. The prosthetic device of claim 3 , wherein each linear segment comprises an identical pattern of recesses.

5. The prosthetic device of claim 3 , wherein the first and second recesses are located on the same linear segment, and each linear segment comprises at least first and second recesses.

6. The prosthetic device of claim 1 , wherein the recesses have a rounded triangular shape.

7. The prosthetic device of claim 1 , wherein the recesses are configured to retain a suture in a whip stitch configuration.

8. The prosthetic device of claim 1 , wherein the recesses are configured to retain a suture in a knot configuration comprising one or more knots.

9. The prosthetic device of claim 1 , wherein the plurality of recesses are disposed continuously along each longitudinal edge forming a sinusoidal curve.

10. A prosthetic valve, comprising:

a radially expandable and compressible frame comprising a plurality of interconnected struts, each strut having a first end, a second end, and a length extending from the first end to the second end, each strut further comprising a plurality of recesses disposed on one or more longitudinal edges of the strut and extending into a width of the strut;

a skirt mounted to the frame via one or more sutures; and

wherein the recesses retain the one or more sutures and prevent the one or more sutures from sliding along the length of the strut.

11. The prosthetic valve of claim 10 , wherein each recess extends radially through a thickness of the strut.

12. The prosthetic valve of claim 10 , wherein each strut comprises a plurality of linear segments that are laterally offset from each other in a direction perpendicular to the lengths of the struts and each linear segment comprises a plurality of recesses.

13. The prosthetic valve of claims 10 , wherein the recesses have a rounded triangular shape.

14. The prosthetic valve of claim 10 , wherein the one or more sutures comprise a whip stitch configuration.

15. The prosthetic valve of claim 14 , wherein when in the whip stitch configuration a suture of the one or more sutures extends through the skirt, around a strut of the plurality of struts, and back through the skirt.

16. The prosthetic valve of claim 10 , wherein the one or more sutures comprise a knot configuration including one or more knots.

17. The prosthetic valve of claim 16 , wherein each of the one or more knots is positioned at a center of a width of the strut.

18. The prosthetic valve of 16 , wherein the one or more knots are positioned on a radially inner surface of the strut.
