Percutaneous aortic valve

摘要

A method of minimally invasively replacing a cardiac valve of a patient including inserting a delivery catheter intraluminally, inserting a valve resecting instrument intraluminally through the delivery catheter to a position adjacent the cardiac valve of a patient, manipulating the valve resecting instrument to resect the cardiac valve, removing the resected valve through the delivery catheter, and providing a delivery instrument having a replacement valve contained therein. The delivery instrument is advanced into the delivery catheter and intraluminally so that a distal end portion of the instrument is adjacent an annulus of a patient, and a first portion of the valve is exposed from the delivery instrument to position it on a first side of the annulus, and thereafter a second portion of the valve is exposed to position it on a second side of the annulus.

1. A method of minimally invasively replacing a cardiac valve of a patient comprising:
inserting a delivery catheter intraluminally, the delivery catheter having a longitudinal axis; inserting a valve resecting instrument intraluminally through the delivery catheter to a position adjacent the cardiac valve of a patient; manipulating the valve resecting instrument from outside the body to resect the cardiac valve; removing the resected valve through the delivery catheter; providing a delivery instrument having a replacement valve contained therein in an elongated reduced profile insertion configuration extending along the longitudinal axis of the delivery catheter; advancing the delivery instrument into the delivery catheter and intraluminally so that a distal end portion of the instrument is adjacent an annulus of a patient; exposing a first portion of the valve from the delivery instrument to position it on a first side of the annulus, the first portion moving to a second larger profile configuration for placement on the first side of the annulus; and thereafter exposing a second portion of the valve to position it on a second side of the annulus, the second portion moving to a second larger profile configuration on the second side of the annulus, the first and second portions providing a clamping force on the annulus.
