1. A delivery system for delivering an implant to a body lumen, the system comprising:
an outer tubular member defining a lumen and having a proximal end region and a distal end region;
an inner tubular member defining a lumen and having a proximal end region and a distal end region, the inner tubular member slidably disposed within the lumen of the outer tubular member and having at least one opening positioned in a side wall adjacent to the distal end region, the at least one opening extending from an outer surface to an inner surface of the inner tubular member;
an expandable implant disposed about the outer surface of the inner tubular member adjacent the 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 including a proximal end region, a distal end region, and a length extending therebetween; and
a thread including a distal portion wrapped around an outer surface of the first flexible portion of the implant a plurality of times with the distal portion of the thread wrapped along the length of the first flexible portion of the implant, the thread configured to maintain the first flexible portion in a collapsed configuration;
wherein the distal end region of the outer tubular member is disposed over the first rigid portion of the implant and is configured to maintain the first rigid portion in a radially collapsed configuration.
