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.
Claims20
A product comprising:
- an endoprosthesis having a body formed of a non-bioabsorbable polymer comprising a cross-linked polycyclooctene, the polycyclooctene having been cross-linked while the endoprosthesis is in an expanded position to provide shape memory to the endoprosthesis, the endoprosthesis being designed for delivery into a body lumen and being in a collapsed state so that the endoprosthesis can be delivered into the body lumen, and wherein the endoprosthesis is capable of reverting from the collapsed state to the expanded state when warmed after delivery to a body lumen.
A product comprising:
- a stent having a metal-free body formed of a non-bioabsorbable polymer comprising a cross-linked polycyclooctene, the polycyclooctene having been cross-linked while the stent is in an expanded position to provide shape memory to the stent, the stent being designed for delivery into a body lumen and being in a collapsed state so that the stent can be delivered into the body lumen, and wherein the stent is capable of reverting from the collapsed state to the expanded state when warmed after delivery to a body lumen.
A product comprising:
- a stent having a body consisting of non-bioabsorbable cross-linked polycyclooctene, the polycyclooctene having been cross-linked while the stent is in an expanded position to provide shape memory to the stent, the stent being designed for delivery into a body lumen and being in a collapsed state so that the stent can be delivered into the body lumen, and wherein the stent is capable of reverting from the collapsed state to the expanded state when warmed after delivery to a body lumen.
