ENDOVASCULAR PROSTHESIS

摘要

A endovascular prosthesis for implantation in a body passageway. The prosthesis comprises a tubular wall which is: (i) movable between a first longitudinal length and a second longitudinally length, and (ii) radially expandible for implantation of the prosthesis in the body passageway. In one embodiment, the tubular wall has a longitudinally length which is variable by an "accordian"-like action. In another embodiment, the tubular wall has a longitudinally length which is variable by an "telescoping"-like action. The longitudinal length of the tubular wall may be varied in vivo to optimize deployment of the endovascular prosthesis.
