Polymeric Transcatheter Aortic Valve Implantation System and Methods

Background: TAVI is a minimally invasive procedure to implant a prosthetic valve inpatients with aortic valve stenosis (AVS). Typical TAVI systems are no longer adjustableonce deployed. The present invention solves this hindrance with the inclusion of the threeimprovements mentioned above.

Invention: The invention is an improvement on current transcatheter aortic valveimplantation (TAVI) methods that allows the prosthetic valve to be steered into positionthrough the artery and adjusted once deployed.  This improvement on the first, and current,TAVI systems includes a hinged prosthetic, a cable system for adjusting the prosthetic in theartery, and handle that controls the adjustments with simple controls (i.e. buttons andtwisting sections).


·Vascular procedures that include transcatheter stent placement

·Commercial medicine


·The prosthetic valve can be manipulated by wires to bend at a hinge

·Steering the distal end of the prosthetic makes for a more navigable path through the artery as it is pushed into place by the catheter

·Alternative to surgery for patients with AVS ·Increases the safety of the method
