Patent Images
1. A prosthetic valve comprising:
- a stent structure comprising a generally tubular body portion having a first end having a first end diameter, a second end having a second end diameter, and a central portion having a central diameter, the central portion being between the first end and the second end, wherein the first end diameter is different from the second end diameter, wherein the central diameter is larger than both the first end diameter and the second end diameter; and
a valve structure attached to the central portion of the generally tubular body portion.

Abstract
A stented valve including a generally tubular stent structure that has a longitudinal axis, first and second opposite ends, a plurality of commissure support structures spaced from the first and second ends and extending generally parallel to the longitudinal axis, at least one structural wire positioned between each two adjacent commissure support structures, and at least one wing portion extending from two adjacent commissure support structures and toward one of the first and second ends of the stent structure. The stented valve further includes a valve structure attached within the generally tubular stent structure to the commissure support structures.
