Protective membrane for reconfiguring a workpiece
First Claim
1. A system for delivering a coated reconfigurable medical implant to a target site comprising:
- a carrier device, the carrier device having a proximal end and a distal end, the distal end having an implant carrying region; and
a reconfigurable deployable medical implant in physical communication with the implant carrying region, the deployable medical implant coated with a coating having therapeutic and reconfigurable from a first expanded configuration to a second contracted configuration, the therapeutic covered by an encasing hollow deformable membrane, the membrane, in an unexpanded state, defining a cavity having a cross-section that is smaller than the external cross-section of the deployable medical implant in its second contracted configuration.

Abstract
A method of protecting the coating on a reconfigurable coated workpiece having a first end and a second end is provided in one embodiment of the present invention. This embodiment includes providing an encasing hollow deformable membrane, positioning the first end of the reconfigurable coated workpiece adjacent to an entrance orifice of the membrane, enlarging the entrance orifice and the inside cavity of the membrane, inserting the reconfigurable coated workpiece into the enlarged entrance orifice and into the inside cavity and decreasing the size of the inside cavity of the membrane until an inside surface of the cavity contacts the coating of the workpiece.
