TRANSAPICAL DELIVERY DEVICE AND METHOD OF USE

摘要

A delivery device for a stented heart valve comprises a handle (132), an inner catheter (135) shaft extending from the handle and having an enlarged bumper element (137) at a distal end, an outer catheter shaft (134) extending from the handle and slidably coupled around the inner catheter shaft, and a retraction mechanism (141) for controlling longitudinal movement of the outer catheter shaft relative to the inner catheter shaft. The outer catheter shaft includes a generally cylindrical housing (136) at a distal end that is structured to receive the bumper element therein.
