Heart valve prosthesis
First Claim
1. A prosthesis comprising:
- a frame having a valve-retaining tubular portion and an inflow portion radially extending from a first end of the valve-retaining tubular portion, wherein the inflow portion is formed from a plurality of struts, wherein each strut has a base segment joined to the valve-retaining tubular portion, wherein each strut has first and second branch segments that diverge from the base segment, wherein the base segment has a twisted area, and wherein each of the first and second branch segments has a respective twisted area, and wherein a cut width of each of the twisted areas 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.
