Abstract
An endolumenal prosthesis delivery assembly includes an endolumenal prosthesis which is delivered to a desired location within a body lumen by used of first and second delivery members. The first delivery member has a prosthesis coupler that is adapted to removeably engage the prosthesis during delivery to the desired location and to release the prosthesis and implant it at the desired location. The second delivery member has an anchor on its distal end portion which is adapted to secure the second delivery member within the body lumen distally of the desired location for stenting. Once the second delivery member is anchored, the first delivery member is slideably advanced over the second delivery member until the prosthesis is positioned at the desired location. The anchor along the second delivery member according to this assembly is either an expandable member, such as a balloon, or is otherwise adapted to engage the body lumen wall, such as by use of suction or other mechanical means. An expansion member on the first delivery member, such as provided at the prosthesis coupler, expands the prosthesis to engage the body lumen wall.
