Abstract
A fixation device fixes the position of an implantable microminiature device residing proximally to a target site such as a nerve or a muscle. In one embodiment, the device comprises a sheath and a means for attaching the device to adjacent tissue. The means for attaching may be any one of several embodiments including one or more grasping members, a combination of grasping members and one or more helices, or an extension adapted to accept a suture. In another embodiment, the fixation device comprises an assembly residing in the implantation pathway, behind the stimulation device, thus preventing retreat of the stimulation device in the pathway. In a preferred use, the fixation device fixes the position of a microstimulator component of a Peripheral Nerve Stimulation (PNS) system.
