摘要: A temporary stent for supporting a region of a vessel in a body comprising a stent portion and an actuator portion and methods for the use and manufacture thereof. The stent portion is comprised of an elongate perfusable vessel supporting portion adapted to be configurable between a reduced size for placement in the vessel and removal therefrom and an expanded size for structurally supporting the vessel and perfusable end portions connected to and forming ends of the vessel supporting portion and adapted to allow fluid flow therethrough. The actuator portion includes a proximal end extending out of the body and a distal end connected to the stent portion and operable by manipulation at the proximal end thereof to configure the support portion into a reduced size and an expanded size.
