摘要：
A delivery device for a stented heart valve that includes a handle, an inner catheter shaft extending from the handle and having an enlarged bumper element at a distal end, an outer catheter shaft extending from the handle and slidably coupled around the inner catheter shaft, and a retraction mechanism for controlling longitudinal movement of the outer catheter shaft relative to the inner catheter shaft. The outer catheter shaft includes a generally cylindrical housing at a distal end that is structured to receive the bumper element therein.
