Claim:
A stabilizer having a stent-underlying portion adapted to be disposed within an interior space defined by an inner periphery of a stent, the stent-underlying portion having a distal end adapted to be positioned adjacent a distal end of the stent, a proximal end adapted to be positioned adjacent a proximal end of the stent, and a length extending from the portion distal end to the portion proximal end, the stabilizer comprising a non-inflatable inner core and one or more members for engaging the stent inner periphery along the stent-underlying portion, wherein the one or more members for engaging the stent inner periphery comprises one or more radial protuberances that protrude from the inner core and lie along the stent-underlying portion of the stabilizer, wherein the one or more radial protuberances comprise at least two sets of rings about the inner core, wherein each set of rings includes at least two rings, each of the at least two rings adjacently positioned, the rings in a first set positioned along a length of the stent-underlying portion extending from the portion's distal end to the portion's proximal end and spaced in a first pattern, and the rings in a second set positioned at either the distal end of the stent-underlying portion or the proximal end of the stent-underlying portion and spaced in a second pattern that is different than the first pattern.
