1. A prosthetic valve device, comprising:
- a valve support structure comprising three deflectable panels arranged to form the periphery of the valve support structure, the valve support structure being transitionable from an undeployed configuration to a deployed configuration, wherein the valve support structure is generally tubular in the deployed configuration and wherein each panel is concave in the undeployed configuration and convex in the deployed configuration;
a plurality of valve leaflets coupled to an inner lumen of the valve support structure; and
a shape retensive panel expansion member comprising a first arm member and a second arm member and biased to deflect the arm members away from each other, the first arm member being coupled to a surface of a first panel and the second arm member being coupled to a surface of an adjacent, second panel such that deflection of the arm members away from each other causes the first and second panels to expand into the generally tubular configuration.

Abstract
Described herein are systems and methods for operation of a prosthetic valve support structure (32) having additional reinforcement coupled with panels (36). Multiple support members (620) are distributed across the inner surface of the valve support structure (32) at regular intervals. Each support member (620) can include a looped portion (621) to act as a hinge (52). Each looped portion (621) is in a location coincidental with the interlace between adjacent panels (36).
