Abstract:
1. A replacement cardiac valve system, comprising: a delivery catheter comprising: an expandable heart valve having an inflow end and an outflow end, collapsible into the restraining sheath and coupled to the retaining structure of the delivery catheter at the outflow end of the expandable heart valve, wherein the restraining sheath is configured to move between a proximal closed position that restrains the expandable heart valve and a distal exposed position that first exposes the inflow end of the expandable heart valve, wherein the retaining structure is configured to restrict proximal longitudinal displacement of the expandable heart valve as the restraining sheath moves between the proximal closed position and the distal exposed position, and wherein the distal flange is configured to restrict distal longitudinal displacement of the expandable heart valve.
