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 center end screw 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.

Claims14

Dependent claims

A method of forming a collapsible medical closure device, the method comprising:

introducing a radiopaque marker band onto one end of a tubular metal fabric formed from a plurality of metal strands being formed from a material that can be heat treated to substantially set a desired shape;
introducing a means for attaching a delivery device inside of the radiopaque marker band;
inverting the tubular metal fabric over itself;
conforming the inverted tubular metal fabric to an internal surface of a molding element, the molding element including a disc shaped portion, a middle portion, and a cone shaped portion;
heating the inverted tubular metal fabric;
removing the tubular metal fabric from the molding element, whereby the tubular metal fabric defines the collapsible medical closure device having a disc shaped portion, a cone shaped portion, and a middle portion connecting the cone shaped portion and the disc shaped portion, wherein the middle portion contains the means for attaching a delivery device and the radiopaque marker band;
and
contacting a therapeutic membrane with the tubular metal fabric.
