Abstract
Devices and methods for making devices that temporarily occlude spaces within the body to provide a therapeutic effect.
Claims20
A method of manufacturing expandable devices, comprising the steps of:
- providing a multi-layer thin film of polymeric material, the multi-layer thin film of polymeric of material comprising a thin film backing layer and a thin film working layer and, wherein the thin film backing layer is disposed on a first side of the thin film working layer;
- positioning the multi-layer thin film on an open frame and heating the multi-layer thin film;
- forming the multi-layer thin film into a device section having a predetermined shape using differential gaseous pressure to conform the multi-layer thin film to a mold, the device section having an inner surface and an outer surface, one backing layer comprising the outer surface, the predetermined shape having a flange region;
- disposing a first device section together with a second device section such that the working layers of the first and second device section are juxtaposed with the flange region of the first device section being in alignment with the flange region of the second device section;
- creating an access hole in at least one of said two device sections;
- joining the flange regions of the device sections to form a fluid tight seam around the flange region;
- trimming an excess material from around the flange region;
- and
- inverting the device though the access hole.

- disposing the first device section together with the second device section such that the working side of the first and second device section are aligned at the respective flange regions;
- creating an access hole in at least either the first or second device sections;
- joining the flange regions of the first and second device sections to form a fluid tight seam around the joined flange regions;
- trimming an excess material from around the flange region;
- and
- inverting the device though the access hole.
