Assembly for placing a prosthetic valve in a duct in the body
First Claim
1. A prosthetic valve assembly comprising:
- a radially expandable stent havinga first expandable annular portion that is configured, in an expanded state, to bear against a wall of a native body lumen, the first expandable annular portion comprising a peripheral protrusion surrounding a distal end of the first expandable annular portion that is configured to form a seal with a wall of a body lumen;
a second expandable annular portion that is configured, in an expanded state, to bear against a wall of a native body lumen, anda plurality of rods extending between the first annular portion and the second annular portion; and
an implantable prosthetic valve mounted to the stent such that the valve is between the first annular portion and the second annular portion,wherein the plurality of rods includes at least one rod having a first portion that contacts the valve and a second portion that does not contact the valve,wherein the prosthetic valve assembly is configured to be delivered by catheterization.

Abstract
A prosthetic valve assembly can include a radially expandable stent. The stent can include a first expandable annular portion that is configured, in an expanded state, to bear against a wall of a native body lumen, a second expandable annular portion that is configured, in an expanded state, to bear against a wall of a native body lumen. The stent can also include a plurality of rods extending between the first annular portion and the second annular portion. The prosthetic valve assembly can further include an implantable prosthetic valve mounted to the stent such that the valve is between the first annular portion and the second annular portion. The prosthetic valve assembly is configured to be delivered by catheterization.
