    摘要： 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 is deployed in connection with an angioplasty procedure with a corewire actuated delivery system having a fixed distal stent-carrying extension. Withdrawal of the corewire retracts a restraint freeing the stent from a collapsed state, whereupon the stent assumes an expanded configuration set in apposition to the interior surface of a vessel lumen in order to help maintain the vessel open.

    摘要： 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.

    摘要： The invention provides endoluminal coil delivery systems and methods for positioning a coil within a body lumen. In particular, the device uses a mechanical latch in the form of jaws to positively engage the coil during positioning. The coil may be restrained in a straight configuration from within the coil, using an internal coilwire, or from outside using a catheter. Thus, the mechanism for releasing the coil to form its relaxed convoluted shape is separate from the mechanism for disengaging the coil from the delivery system. The use of an internal core wire allows a coil having a helical outer surface to be torqued against a fallopian tube or other body lumen wall, thereby firmly anchoring the coil in the target position prior to disengaging the delivery system.
