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. ## Claims ### Claim 1 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. ### Claim 2 (depends on 1) The method of claim 1 further including circumferentially joining the tubular metal fabric, the means for attaching a delivery device, and the radiopaque marker band before inverting the tubular metal fabric over itself. ### Claim 3 (depends on 2) The method of claim 2 wherein circumferentially joining the tubular metal fabric, the means for attaching a delivery device, and the radiopaque marker band comprises welding the tubular metal fabric, the means for attaching a delivery device, and the radiopaque marker band. ### Claim 4 (depends on 2) The method of claim 2 further including trimming a portion of the tubular metal fabric extending past the radiopaque marker band and the means for attaching a delivery device prior to circumferentially joining the tubular metal fabric, the means for attaching a delivery device, and the radiopaque marker band. ### Claim 5 (depends on 1) The method of claim 1 further including introducing a second radiopaque marker band onto the tubular metal fabric after the tubular metal fabric is inverted. ### Claim 6 (depends on 5) The method of claim 5 further including cutting the tubular metal fabric to a desired length after inverting the tubular metal fabric and prior to introducing the second radiopaque marker band onto the tubular metal fabric. ### Claim 7 (depends on 5) The method of claim 5 wherein introducing a second radiopaque marker band onto the tubular metal fabric includes swaging the second radiopaque marker band to lock the second radiopaque marker band to the tubular metal fabric. ### Claim 8 (depends on 7) The method of claim 7 further including trimming a portion of the tubular metal fabric extending from the second radiopaque marker band. ### Claim 9 (depends on 8) The method of claim 8 further including welding the second radiopaque marker band to produce a dome weld. ### Claim 10 (depends on 1) The method of claim 1 wherein contacting the therapeutic membrane with the tubular metal fabric includes connecting a delivery cable to the means for attaching a delivery device, pulling on the delivery cable in a direction opposite the second radiopaque marker band to elongate the tubular metal fabric, removing the delivery cable, inserting the therapeutic membrane through the means for attaching a delivery device, and positioning the therapeutic membrane within the tubular metal fabric. ### Claim 11 (depends on 10) The method of claim 10 wherein inserting the therapeutic membrane through the means for attaching a delivery device and positioning the therapeutic membrane within the tubular metal fabric includes inserting a first therapeutic membrane through the means for attaching a delivery device and positioning the first therapeutic membrane within the tubular metal fabric such that the first therapeutic membrane is positioned within the disk shaped portion of the collapsible medical closure device. ### Claim 12 (depends on 11) The method of claim 11 further including inserting a second therapeutic membrane through the means for attaching a delivery device and positioning the second therapeutic membrane within the tubular metal fabric such that the second therapeutic membrane is positioned within the cone shaped portion and the middle portion of the collapsible medical closure device. ### Claim 13 (depends on 12) The method of claim 12 further including securing the first therapeutic membrane to the disk shaped portion and securing the second therapeutic membrane to at least one of the cone shaped portion and the middle portion of the collapsible medical closure device. ### Claim 14 (depends on 13) The method of claim 13 wherein securing the first therapeutic membrane and the second therapeutic membrane includes at least one of tucking a portion of the first therapeutic membrane and the second therapeutic membrane between picks of the tubular metal fabric and sewing the first therapeutic membrane and the second therapeutic membrane to the tubular metal fabric.
