Device and System for Transcatheter Mitral Valve Replacement
First Claim
1. A prosthetic heart valve which comprises an expandable tubular stent having a cuff and an expandable internal leaflet assembly, wherein said cuff is comprised of wire covered with stabilized tissue or synthetic material, wherein said leaflet assembly is disposed within the stent and is comprised of stabilized tissue or synthetic material, wherein one or more tethers are attached to the prosthetic heart valve and wherein one of such tethers is attached to an epicardial tether securing device.

Abstract
This invention relates to the design and function of a compressible valve replacement prosthesis which can be deployed into a beating heart without extracorporeal circulation using a transcatheter delivery system. The design as discussed focuses on the deployment of a device via a minimally invasive fashion and by way of example considers a minimally invasive surgical procedure preferably utilizing the intercostal or subxyphoid space for valve introduction. In order to accomplish this, the valve is formed in such a manner that it can be compressed to fit within a delivery system and secondarily ejected from the delivery system into the annulus of a target valve such as a mitral valve or tricuspid valve.
