1. A method comprising:
- initiating deployment of a self-expanding stent comprising capture segments;
recapturing said self-expanding stent by sequentially collapsing said capture segments by a distal end of a sheath, wherein each of said capture segments captures the immediately adjacent distal capture segment during said recapturing;
repositioning said self-expanding stent; and
redeploying said self-expanding stent.

Abstract
A self-expanding stent includes capture segments including a first capture segment and a second capture segment. The first capture segment includes a first crown coupled to a first crown of the second capture segment and a second crown, where the second crown is spaced apart from an adjacent second crown of the second capture segment when the self-expanding stent is in a relaxed state, and further where the second crown of the first capture segment captures the adjacent second crown of the second capture segment when the self-expanding stent is in a radially compressed state.

4. A method comprising:
-
initiating deployment of a self-expanding stent comprising capture segments; recapturing said self-expanding stent by sequentially collapsing said capture segments into a funnel shape by a distal end of a sheath, wherein each of said capture segments captures the immediately adjacent distal capture segment during said recapturing; repositioning said self-expanding stent; and redeploying said self-expanding stent.

5. A method of recapturing a stent comprising:
radially compressing said stent to cause a crown of a first segment of said stent by sequentially collapsing capture segments to move longitudinally relative to a crown of a second segment of said stent so that said first segment captures said second segment.
