Surgical insertion tool
First Claim
1. A surgical system comprising:
- an implant comprising an electrode that is biasable to deliver electrical pulses; and
a tool system, comprising;
a cannula;
a stimulating probe configured for being removably retained and secured within the cannula, the stimulating probe comprising an electrode that is biasable to deliver electrical pulses configured to stimulate tissue in a manner that indicates whether a location is suitable as an implant site for the electrode of the implant to deliver the electrical pulses to a nerve; and
an implant holder configured for being removably retained and secured within the cannula;
an implant disengagement assembly configured to disengage the implant from the implant holder;
wherein the electrode of the stimulating probe and the electrode of the implant are located in the same position relative to the cannula when the stimulating probe and implant holder are retained and secured within the cannula.

Abstract
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 The components of the tool are configured to maintain the implant at the target location while the tool is withdrawn.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.

16. A surgical system comprising:
-
an implant comprising an electrode that is biasable to deliver electrical pulses; stimulating means comprising an electrode biasable to deliver electrical pulses for locating a proper implant site, wherein the proper implant site allows the implant to deliver the electrical pulses to a nerve; means for providing access to position the implant at the proper implant site; means for engaging the implant with the electrode exposed; means for removably retaining and securing the stimulating means within the means for providing access; and means for removably retaining and securing the implant engaging means within the means for providing access; wherein the electrode of the stimulating means and the electrode of the implant are located in the same position relative to the means for providing access when the stimulating means and implant engaging means are retained and secured within the means for providing. - View Dependent Claims (17, 18, 19)
