1. A stent delivery system comprising:
- an elongate delivery guide body releasably securing with at least one electrolytic member a stent with a mesh, lattice, or woven structure, the stent being in a twisted state and biased to untwist from the twisted state, and wherein the stent is mounted at a distal portion of the delivery guide,wherein at least a portion of the stent is restrained by a sleeve that is held in a restraining position by the at least one electrolytic member, wherein the stent is maintained in the twisted state by the sleeve in the restraining position, wherein the sleeve is biased to be in a non-restraining position;
wherein the sleeve is biased to be in the non-restraining position by a spring connected between the sleeve and a portion of the elongate delivery guide body.

Abstract
Medical devices and methods for delivery or implantation of prostheses within hollow body organs and vessels or other luminal anatomy are disclosed. The subject technologies may be used in the treatment of atherosclerosis in stenting procedures or be used in variety of other procedures. The systems may employ a self expanding stent restrained by one or more members released by an electrolytically erodable latch. Such release means do not connect directly to the implant, though one or more portions may contact it.
