First Claim
Patent Images
1. A method of loading a self-expanding stent onto a delivery guide, the method comprising:
- providing a closed cell, self-expanding stent having a near end, a far end, a radially expanded configuration when unconstrained, and a compressed and lengthened configuration when radially constrained;
placing the stent in at least one sleeve member to radially constrain the stent in said compressed and lengthened configuration;
twisting the stent while the stent is in the sleeve member by rotating at least one end of the stent relative to the other;
releasably securing the twisted stent to the delivery guide so that it can radially expand when released, wherein the stent is twisted prior to securing an end of the stent to the delivery guide; and
removing the at least one sleeve member from over the stent to leave the stent on the delivery guide prior to deployment.

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.
