Claim 0:
1. A delivery system, comprising:
a flexible elongate member;
an inner member slidably disposed within a lumen of the flexible elongate member, a distal portion of the inner member comprising a shape memory material;
a stent loaded in a first constrained configuration between a distal portion of the flexible elongate member and a distal portion of the inner member; and
a tissue penetrating element on the distal portion of the inner member, the tissue penetrating element configured to form an opening in tissue,
wherein the stent is configured to move from the first constrained configuration to a second deployed configuration when unconstrained from the flexible elongate member; and
wherein the shape memory material is configured to form into a plurality of preformed loops, curls, waves, or peaks and valley to foreshorten the inner member from a first length when disposed within the distal portion of the flexible elongate member to a second length when the stent is unconstrained from the flexible elongate member, the first length being greater than the second length.
