Abstract
Improved systems, devices, and methods for deployment of endoluminal prostheses within the lumens of the body, and particularly for deployment of stents and stent-grafts within the vascular system. Optionally a sheath is withdrawn from over a tightly compressed prostheses using an actuation mechanism having a variable mechanical advantage, which varies with the position of the sheath. The handle for the actuation mechanism may rotate about an axis parallel to the axis of the sheath. The deployment systems of the present invention will preferably include a “one-way” rotation mechanism, thereby avoiding any inadvertent counter-rotation of the handle causing undesirable movement of the prosthesis or delivery system.
