Abstract
Abstract A deployment system for transcutaneous insertion of an implantable tubular prosthesis is provided. The deployment system includes a flexible, elongated, tubular, delivery catheter with at least one inner lumen, and an opening extending through the catheter to the inner lumen. Positioned over the catheter is an implantable endoprosthesis capable of radial expansion and having a proximal and a distal end extent. A support assembly removably maintains the endoprosthesis in a compressed state, and is located at a position adjacent the catheter opening. The support assembly includes an arm which extends through the catheter opening into the inner lumen. A release mechanism is insertable through the inner lumen and includes a distal tip engageable with the arm of the support assembly. The release mechanism is manipulatable within the inner lumen so as to remove the support assembly from the endoprosthesis, permitting radial expansion of the endoprosthesis for implantation.
