Implant tool for use with a microstimulator
First Claim
1. A stimulation system, comprising:
- an insertion tool comprisingan insertion cannula,a handle at a proximal end of the insertion cannula for grasping the insertion cannula,a bushing-based advancing mechanism situated within the insertion cannula and comprising a bushing arranged to push the implantable microstimulator longitudinally within the insertion cannula when the implantable microstimulator is placed within a lumen of the insertion cannula,a detachable blunt dissector tip at the distal end of the cannula, anda tail attached to the detachable blunt dissector tip, andan implantable microstimulator with the tail coupled at a distal end of the implantable microstimulator and useable to constrain movement of the implantable microstimulator within tissue, wherein the microstimulator comprises a housing, a power source disposed within the housing, and at least one electrode disposed on the housing.

Abstract
A stimulation system is described that includes an implantable microstimulator. A tail may be coupled to a distal end of the implantable microstimulator. In one embodiment, the stimulation system includes an implantation tool that includes an insertion cannula, a handle, a bushing, and a detachable blunt dissector tip. The bushing is situated within the insertion cannula and may position the implantable microstimulator longitudinally within the insertion cannula when the implantable microstimulator is placed within the insertion cannula. The detachable blunt dissector tip may be attached to the tail of the implantable microstimulator. The stimulation system may further comprise an end cap that includes an upper portion and a base portion conformable over at least a portion of curved tissue. An open trough extends through the base upper portions and may be configured to guide the implantation tool through the tissue at various angles.
