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.
