Disk-Based Valve Apparatus and Method for the Treatment of Valve Dysfunction

摘要

The present invention comprises a novel and safer mechanism of deployment using a self-positioning, self-centering, and self-anchoring method. To embody the present invention, a disk-based valve apparatus allowing the repositioning and retrieval of the implantable valve while working on a dysfunctional valve structure is disclosed. The disk-based valve apparatus may comprise one or more disks, either proximal or distal, a valve-housing component and a valve component. The one or more disks may be either proximal or distal, may be either connected to each other or disconnected from each other and may either be symmetrical or have different shapes and dimensions. The disk-based valve apparatus may be self anchoring, such as anchored by pressure from the one or more disk, or may be anchored using any anchoring.

主权项

1. A method of deploying a prosthetic cardiac valve in a patient, the method comprising:
inserting the prosthetic cardiac valve within a dysfunctional mitral valve in the patient's heart; permitting a distal portion of a valve anchor to self-expand; pulling the distal portion of the valve anchor proximally into a plane of the dysfunctional mitral valve; permitting a proximal portion of the valve anchor to self-expand on an opposite side of the dysfunctional mitral valve; and permitting a central portion of the valve anchor to self-expand within the dysfunctional mitral valve to move the distal and proximal portions of the valve anchor toward each other to compress the dysfunctional mitral valve.
