Heart valve prosthesis
First Claim
1. A mitral valve prosthesis comprising:
- a frame having an inflow portion, a valve-retaining tubular portion and a pair of support arms, the inflow portion radially extending from a first end of the valve-retaining tubular portion and the pair of support arms being circumferentially spaced apart and extending from an opposing second end of the valve-retaining tubular portion,wherein the inflow portion is formed from a plurality of struts that outwardly extend from the first end of the valve-retaining tubular portion with adjacent struts of the plurality of struts being joined,wherein each strut of the plurality of struts has a substantially s-shaped profile,wherein each strut has a base segment joined to the valve-retaining tubular portion and wherein the base segment has a twisted area,wherein each strut has first and second branch segments that diverge from the base segment and wherein each of the first and second branch segments has a respective twisted area, andwherein a cut width of each of the twisted areas of the respective strut is turned one of clockwise or counterclockwise relative to an initial position of the cut width in a cut pattern of the frame.

Abstract
Mitral valve prosthesis are disclosed that include a frame or support structure having an inflow portion, a valve-retaining tubular portion and a pair of support arms. The inflow portion radially extends from a first end of the valve-retaining tubular portion and the pair of support arms are circumferentially spaced apart and radially extend from an opposing second end of the valve-retaining tubular portion. The inflow portion is formed from a plurality of struts that outwardly extend from the first end of the valve-retaining tubular portion with adjacent struts of the plurality of struts being joined, wherein each strut of the plurality of struts has a substantially s-shaped profile and at least one twisted area.

9. A mitral valve prosthesis comprising:
-
a frame having an inflow portion, a valve-retaining tubular portion and a pair of support arms, the inflow portion radially extending from a first end of the valve-retaining tubular portion and the pair of support arms being circumferentially spaced apart and extending from an opposing second end of the valve-retaining tubular portion, wherein the inflow portion is formed from a plurality of struts that outwardly extend from the first end of the valve-retaining tubular portion with adjacent struts of the plurality of struts being joined, wherein each strut of the plurality of struts has a substantially s-shaped profile and at least one twisted area, wherein each strut has a base segment joined to the valve-retaining tubular portion and wherein the base segment has a twisted area, wherein a pair of base segments radially extends from every other valley at the first end of the valve-retaining tubular portion, and wherein the twisted area of a first base segment of each pair of base segments twists in an opposite direction from the twisted area of a second base segment of each pair of base segments.

10. A mitral valve prosthesis comprising:
-
a frame having an inflow portion, and a valve-retaining tubular portion, wherein in a deployed configuration the inflow portion of the frame radially extends from a first end of the valve-retaining tubular portion, and wherein the inflow portion of the frame is comprised of a plurality of struts with each strut forming a substantially s-shaped profile when radially extending from the first end of the valve-retaining tubular portion in the deployed configuration, wherein each strut is Y-shaped having a base segment and first and second branch segments that diverge from the base segment, wherein the base segment of each strut is joined to the valve-retaining tubular portion and wherein the base segment has a twisted area, wherein each of the first and second branch segments of each strut has a respective twisted area, and wherein a cut width of each of the twisted areas of the respective strut is turned one of clockwise or counterclockwise relative to an initial position of the cut width in a cut pattern of the frame. - View Dependent Claims (11, 12, 13, 14, 15)
