Claim Text:
1. An implant deployment system, comprising: a deployment device; and a self-expanding implant disposed on the deployment device and having a proximal end, a distal end, a central portion between the proximal end and the distal end, a first expanded configuration and a second expanded configuration, a stent disposed adjacent one of or both of the proximal and distal ends and having apices; the deployment device comprising: an implant release mechanism for releasably retaining the implant on the deployment device, the implant release mechanism including an elongate implant support having a proximal implant restraining location disposed substantially adjacent the implant proximal end and a distal implant restraining location disposed substantially adjacent the implant distal end; a proximal wire holding element at the proximal implant restraining location and a distal wire holding element at the distal implant restraining location; and at least one common release wire having an implant proximal end restraining portion and an implant distal end restraining portion, wherein one of or both of the proximal wire holding element and the distal wire holding element comprises a single thread having at least three loops, wherein each of the at least three loops of the one or both of the proximal wire and distal wire holding elements engages one or more of the apices and an implant end restraining portion of the at least one common release wire, and wherein each loop of the plurality of loops forms a loop between an apex of the apices and the at least one common release wire, and wherein each of the apices is coupled to one of the plurality of loops; where in the first expanded configuration the release wire proximal end restraining portion is restrained by the proximal wire holding element and the release wire distal end restraining portion is restrained by the distal wire holding element so as to restrain the implant at both the proximal and distal locations; and where in the first expanded configuration the at least one release wire restrains both the proximal and distal ends of the implant without restraining the central portion of the implant such that the central portion is at least partially expanded relative to the proximal and distal implant ends.
