RETAINING MECHANISMS FOR PROSTHETIC VALVES

摘要

Disclosed herein are representative embodiments of methods, apparatus, and systems used to deliver a prosthetic heart valve to a deficient valve. In one embodiment, for instance, a support member is positioned to at least partially surround the native leaflets of a valve. A locking member is used to couple both ends of the support member, forming a support band. An expandable prosthetic heart valve is delivered into the native heart valve and expanded while the expandable prosthetic valve is at least partially within the support band, thereby causing one or more of the native leaflets of the native heart valve to be frictionally secured between the support band and the expanded prosthetic heart valve.

1. A method comprising:
advancing a delivery catheter into a body of a patient; advancing a cord distally through the delivery catheter such that a distal end portion of the cord extends beyond a distal end of the delivery catheter and the cord curves around tissue in the heart; and capturing the distal end portion of the cord with a snare.
