Abstract
A delivery device for placing an implant or prosthesis inside a body is described. The device is useful for placing a variety of stents or implants when used with a cystoscope or other visualization or placement device. An inner sheath is relatively stiff and an outer sheath is relatively pliable or soft compared to the inner sheath. The sheaths are assembled to a connector and a positioner is then inserted through the center of the assembly, the inner sheath. The implant is placed near the distal end of the outer sheath, and the assembled device with the implant is backloaded onto a cystoscope or endoscope for placement. The inner sheath may be used to tailor the stiffness or rigidity of the assembled delivery device.
