1. A stenting system comprising:
- a self-expanding stent;
a corewire including a distal stent-receiving region, a solid raised feature on the corewire sized to abut at least a portion of the stent, and an inner sleeve and an outer sleeve set over the corewire;
wherein the corewire has a reduced distal diameter section;
wherein the inner sleeve has a proximal end located along the reduced diameter section; and
wherein the outer sleeve is adapted to restrain the stent in a compressed state.
