Abstract

Treating a site within the body, e.g., placing endoprosthesis (26) into the body, with a catheter (12) having a proximal portion (20) remaining outside the body and a shaft (14) for positioning inside the body. The shaft (14) includes in a distal portion (22) a selectively expandable member (18) which can be expanded from a small cross-sectional profile for receiving said endoprosthesis (26) about said expandable member (18) in a compact configuration and a large, expanded cross-sectional profile for expanding said prosthesis during placement into the body, and an elastic strip (30, 32) wrapped in helical fashion about said expandable member such that the strip (30, 32) is stretched when said expandable member (18) is expanded to said large cross-sectional profile.
