Contoured heart valve suture rings |
摘要 |
Prosthetic heart valve suture rings having a suturable annulus of a compliant internal member and a cloth covering. Three evenly spaced upwardly opening depressions formed on an internal circumference of the suturable annulus receive downwardly-directed cusps of a stent structure of the heart valve. The suture ring may include a silicone sponge waffle annulus having a walled lip on an inner circumference thereof. The lip is contoured to include the three depressions, and a ring washer mounts on the annulus surrounding the walled lip for added stiffness.
