Support apparatus to facilitate implantation of cardiac prosthesis
First Claim
1. An implantable apparatus, comprising:
- a substantially rigid and annular base portion having a radially outer sidewall portion and having a radially inner sidewall portion that defines an opening that extends axially through the base portion;
a first rim portion extending substantially radially outwardly from the radially outer sidewall portion; and
a second rim portion extending substantially radially outwardly from the radially outer sidewall portion at an axial location that is spaced apart from the first rim portion so as to define a substantially continuous annular channel that extends circumferentially along the radially outer sidewall portion intermediate the first rim portion and second rim portion.

Abstract
An apparatus includes substantially rigid and annular base portion having a radially outer sidewall portion and having a radially inner sidewall portion that defines an opening that extends axially through the base portion. A first rim portion extends substantially radially outwardly from the radially outer sidewall portion. A second rim portion extends substantially radially outwardly from the radially outer sidewall portion at an axial location that is spaced apart from the first rim portion so as to define a substantially continuous annular channel that extends circumferentially along the radially outer sidewall portion intermediate the first rim portion and second rim portion. The apparatus can be covered with a substantially biocompatible material.

20. A cardiac prosthesis comprising:
-
an annular base portion having inflow and outflow end portions spaced apart by a substantially annular sidewall portion that is configured to maintain a circumferential length thereof, an aperture extending axially through the base portion;
a flexible covering of a substantially biocompatible material that connected over at least a radially outer surface of the sidewall portion; and
at least one feature that extends circumferentially around the sidewall portion and covered by the covering to form at least one corresponding chamber that is defined by the covering, the at least one feature and a portion the radially outer surface of the base portion. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32)
