Inversion delivery device and method for a prosthesis
First Claim
Patent Images
1. A method for delivering an implant to a target location comprising:
- navigating a delivery catheter containing an implant to a target location, said implant being connected to said delivery catheter with a plurality of tethers;
deploying said implant from a distal end of said delivery catheter at a first rate;
verifying desired operation of said implant at the target location prior to releasing said implant;
retracting said implant into said delivery catheter at a second rate faster than said first rate if said verification step indicates an undesirable deployment;
releasing said implant from said delivery catheter if said verification step indicates a desirable deployment.

Abstract
A delivery device usable to deliver an inverting implant is provided that includes a positioning mechanism that automatically initiates the inversion process once a predetermined length of the implant has exited a delivery catheter. The positioning mechanism allows the implant to be safely and accurately deployed with reduced operator experience and in a greater variety of target locations.
