  • Publication number: 20090281611
    Abstract: Medical device 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. For such purposes, a self-expanding stent may be deployed in connection with an angioplasty procedure with a sliding restraint based delivery system adapted for simplified use. In the system, the sliding restraint is sized, in coordination with a fixed sleeve accepting a core wire to actuate the restraint to effect an anchoring function with the sleeve so that the stent is not inadvertently advanced during deployment.
