An endo luminal support structure (10) includes strut members (11) interconnected by swivel joints (15) to form a series of linked scissor mechanisms. The structure can be remotely actuated to compress or expand its shape by adjusting the scissor joints within a range of motion. In particular, the support structure can be repositioned within the body lumen or retrieved from the lumen. The support structure can be employed to introduce and support a prosthetic valve (100) within a body lumen. |
