1. A method, comprising:
- providing an implant;
shaped so as to define a lumen therethrough and a flexible strip disposed at least in part within the lumen of the implant, the strip having;
a first end,a second end, anda plurality of recesses, andincluding a locking mechanism to which the first and second ends of the strip are coupled such that the strip defines a closed loop and a perimeter thereof which (a) shortens when the first end is advanced through the locking mechanism in a first direction and (b) expands when the first end is advanced in a second direction opposite the first direction;
advancing the first end of the strip in first and second opposing directions with respect to the second end of the strip;
maintaining a recess-engaging portion in a position in which the recess-engaging portion is not disposed in any of the plurality of recesses during the advancing; and
