Abstract
Various methods and devices for deploying a stent a lumen are provided. In one exemplary embodiment, the stent deployment device can include an elongate shaft having at least one actuator coupled thereto and adapted to radially expand upon delivery of energy thereto. The device can also include a retractable sheath disposed therearound and adapted to maintain the stent on the actuator during deployment of the device.

18. A method for implanting a stent, comprising:
-
inserting a substantially flexible elongate shaft into a lumen;
positioning an actuator located on a distal portion of the flexible elongate shaft within a lumen, the actuator having a stent disposed therearound; and
electrically actuating the actuator to cause the actuator to expand radially, thereby deploying the stent into tissue surrounding the lumen. - View Dependent Claims (19, 20, 21, 22)
