Abstract:
1. A stent delivery device comprising: a self-expanding stent having an expanded configuration and a compressed configuration; a push wire; a first retaining polymer attached directly to and directly contacting the push wire and disposed about and retaining a proximal end portion of the self-expanding stent in the compressed configuration; a second retaining polymer attached directly to and directly contacting the push wire and disposed about and retaining a distal end portion of the self-expanding stent in the compressed configuration; a first resistance member in thermal communication with the first retaining polymer; and a second resistance member in thermal communication with the second retaining polymer; wherein the second retaining polymer and the second resistance member are configured to permit expansion of the distal end portion of the self-expanding stent to an expanded configuration without expansion of the proximal end portion of the self-expanding stent.
