Abstract
The present disclosure provides an improved collapsible medical closure device fabricated from a tubular wire mesh material. The collapsible medical closure device has an expanded preset configuration and an elongated collapsed reduced diameter configuration for delivery through a delivery catheter or other delivery means to a desired treatment site. The collapsible medical closure device is shaped to create short-term and long-term occlusion of an opening, such as an opening in the wall of the heart, and includes a disc shaped portion on a distal end, a cone shaped portion on a proximal end, a middle portion connecting the disc shaped portion and the cone shaped portion, and a means for attaching a delivery cable located in the middle portion. The collapsible medical closure device additionally includes a therapeutic membrane for aiding in occlusion and promoting tissue growth, as well as one or more radiopaque marker bands.
