Low-profile heart valve sewing ring and method of use
First Claim
1. A sewing ring attached to a generally annular periphery of a prosthetic heart valve having an inflow end and an outflow end, comprising:
- a suture-permeable ring attached to the heart valve periphery and configured to pivot from a first position extending generally toward the outflow end of the valve to a second position extending generally toward the inflow end of the valve, wherein first and second positions are stable such that the sewing ring is bi-stable.

Abstract
A sewing ring for prosthetic heart valves that is connected and configured to pivot outward. A biocompatible fabric covering surrounds at least a portion of the sewing ring, and the ring may be exclusively connected to a stent with the fabric. The sewing ring may be generally planar and of uniform thickness, or may be of varying thickness. The fabric may be used to encompass both the stent and the sewing ring, and may be a single piece. A seam may be provided in the fabric as a discrete pivoting line. The sewing ring may be convertible between bi-stable positions. The ring may extend outward in a frusto-conical shape so as to enable inversion between a position facing the inflow end of the valve and a position facing the outflow end of the valve. The sewing ring may have a compliant insert having a celled construction defined by outer walls and inner ribs. A method of implantation, and a method of assembly of the heart valve is also provided.

11. A prosthetic heart valve having an inflow end and an outflow end, comprising:
-
a generally annular stent, and a suture-permeable sewing ring attached to a periphery of the stent so as to be moveable between two positions, wherein in the first position the sewing ring extends generally toward the outflow end of the valve and in the second position the sewing ring extends generally toward the inflow end of the valve, wherein first and second positions are stable such that the sewing ring is bi-stable. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20, 21)
