Stent and sleeve deployment

A delivery system for delivering an implant to a body lumen, the system comprising:

• an outer tubular member defining a lumen;
• an inner tubular member defining a lumen and being slidably disposed within the lumen of the outer tubular member;
• an expandable implant disposed about an outer surface of the inner tubular member adjacent a distal end region of the inner tubular member, the implant comprising at least a first rigid portion and a first flexible portion, the first flexible portion having a proximalmost end, a distalmost end, and a longitudinal length extending therebetween;
• and
• a thread including a distal portion wrapped around only the first flexible portion a plurality of times to thereby maintain an entirety of the longitudinal length of the first flexible portion in a radially collapsed configuration;
• wherein the first rigid portion is devoid of wrapping by the thread;
• and
• wherein a distal end region of the outer tubular member is disposed over the first rigid portion and is configured to maintain the first rigid portion in a radially collapsed configuration.

• an expandable implant disposed about an outer surface of the inner tubular member adjacent a distal end region of the inner tubular member, the implant comprising a self-expandable stent frame and a flexible sleeve fixed to the stent frame, the flexible sleeve having a proximalmost end, a distalmost end, and a longitudinal length extending therebetween;
• and
• at least a first thread including a distal portion wrapped around an outer surface of the flexible sleeve and forming a plurality of releasable knots, the first thread wrapped in one of a proximal-to-distal or distal-to-proximal direction thereby maintaining an entirety of the longitudinal length of the flexible sleeve in a radially collapsed configuration, the self-expandable stent frame being devoid of any wrapping by the first thread;
• wherein a distal end region of the outer tubular member is disposed over the stent frame of the implant to maintain the stent frame in a radially collapsed configuration.
