DEVICES, SYSTEMS, AND METHODS FOR IMPROVING PELVIC FLOOR DYSFUNCTION

摘要

An apparatus for delivering an electrical microstimulator having a microstimulator body comprises a handle having a handle body. An elongate delivery rod includes a delivery sleeve and a stretching shaft, with one of the delivery sleeve and the stretching shaft configured for reciprocal movement with respect to the handle body, and the other extending longitudinally from, and stationary relative to, the handle body. The delivery sleeve selectively engages a fixation aperture of a microstimulator docking feature having a fixation base and a fixation member, concurrent with the stretching shaft engaging a proximal end of the microstimulator body. Longitudinal motion of the delivery sleeve with respect to the stretching shaft causes longitudinal motion of the fixation base to responsively move the fixation member between substantially linear and substantially coiled states. A method of delivering an electrical microstimulator to a target implant site of a patient's body is also provided.
