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.

- 74. A retrieval method for quickly removing a prosthetic heart valve having one or more tethers from a patient that is comprised of the steps of capturing the one or more tethers with a catheter having a snare attachment, guiding the captured tethers into a collapsible funnel attachment connected to removal catheter, pulling the tethers to conform the prosthetic heart valve into a collapsed, compressed conformation, and pulling the now compressed prosthetic heart valve into the removal catheter for subsequent extraction.
