Abstract
A medical device includes a balloon catheter having an expandable member, e.g., an inflatable balloon, at its distal end and a stent or other endoprosthesis. The stent is, for example, an apertured tubular member formed of a polymer and is assembled about the balloon. The stent has an initial diameter for delivery into the body and can be expanded to a larger diameter by inflating the balloon.
Claims25
A method of treating a non-vascular cavity or lumen in a mammal, the method comprising:
- inserting, into the non-vascular lumen or cavity of the mammal, a polymeric stent comprising magnetic metal particles and having a portion in a collapsed position that can be reverted to an expanded position by heating by magnetic effects following insertion of the polymeric stent;
- and
- heating the inserted stent sufficiently by magnetic effects to revert the portion in the collapsed position to the expanded position.
