摘要:
The present invention provides a system and method for providing a coating on a self-expandable medical device, such as a stent, while avoiding the issues relating to coating damage from the delivery sheath during loading and deployment. In one embodiment, the present invention includes a constrictive coating that acts as a constrictive sheath for the stent. A cutting mechanism is mounted on the end of the delivery tube such that when the stent with the constrictive coating exits the delivery tube, the constrictive coating is cut. This releases the constriction retaining the sheath, and the stent self-expands, pressing the cut portions of the coating against the lumen wall.
