A tool is provided for facilitating determining a proper location for an implantable device or medication, and for then delivering the
implant to the precise location determined with the tool. To determine the target location, the tool may include a component for testing target locations, such as a stimulating probe for simulating a miniature implantable stimulator. In one embodiment, the tool is used to test a miniature implantable stimulator prior to depositing the
implant precisely at the target location. The components of the tool are configured to maintain the
implant at the target location while the tool is withdrawn. In one embodiment, a push rod
assembly of the tool keeps the implant in position while it retracts the implant holder from around the implant. The ergonomic and light-weight tool leads to reduced surgical time, number and size of incisions,
risk of infection, and likelihood of error.
