Abstract:
1. An introducer system for deploying an implant in a lumen of a body, comprising: a self-expanding implant comprising: a proximal end and a distal end; a lumen extending between the proximal end and the distal end; a first segment having a constrained configuration and an expanded configuration; a second segment having a constrained configuration and an expanded configuration adjacent the first segment; a carrier to which the implant is mounted; a release wire catheter; and a constraining mechanism constraining the first segment, including a first release wire and circumferentially spaced wire-receivers, the wire-receivers attached to the first segment and extending inwardly from an inner surface of the first segment and releasably engaged to the first release wire; wherein the wire-receivers and the first release wire together radially constrain the first segment of the implant in its constrained configuration; and wherein in a first configuration of the implant, the second segment is expanded and the first segment is constrained, and in a second configuration of the implant, both the first and second segments are expanded, and wherein the wire receivers are attached to the release wire such that the wire receivers are prevented from sliding independently relative to each other and the release wire catheter.
