SYSTEMS AND METHODS FOR VALVE DELIVERY

摘要

A system (100) having an elongate delivery catheter (102), an elongate mesh body (104) including an expandable region positioned around at least a portion of the elongate delivery catheter, a retractable member (130) that extends through the elongate delivery catheter to connect to the elongate mesh body, where the retractable member moves to radially expand the expandable region of the elongate mesh body from an undeployed state to an intermediate state. The system also includes a valve (106) positioned around at least a portion of the elongate delivery catheter position, and a filter (108) positioned around at least a portion of the elongate delivery catheter to filter and control fluid flow.
