Abstract
A subcutaneous tunneling and carrying tool has a handle, a rod, and a carrier. The tool is used in connection with the implantation of electrical stimulators within the body, and more particularly facilitates the surgical procedure in the connection of an electrode lead extension to the implantable stimulator when the electrode and stimulator may not be co-located. In one embodiment, tunneling is accomplished by a tip that also serves to connect the tool to a disposable carrier in which the lead extension connector is packaged. In another embodiment the carrier comprises a carrier body and a removable cover, wherein the carrier cover covers a carrier cavity during tunneling and includes a tunneling end, and the carrier cover is removed after tunneling to expose the carrier cavity, into which carrier cavity the electrode lead extension is inserted to carry back through the tunnel.

4. The tool of claim 3 wherein the carrier cover is removably attachable to the carrier body, wherein when the carrier cover is attached, the carrier cavity is covered, and wherein when the carrier cover is removed, the carrier cavity is uncovered.
-
5. The tool of claim 4 wherein the carrier body includes a means for retaining the carrier cover, and the carrier cover includes a means for cooperating with the means for retaining.
-
6. The tool of claim 5 wherein the means for retaining comprises an O-ring held in a groove on the exterior of the carrier body, and wherein the means for cooperating comprises an O-ring channel in the carrier body, wherein the O-ring is substantially captive in the groove in the carrier body, and wherein the carrier cover is slid over the exterior of the carrier body and when the carrier cover is in place on the carrier body, the O-ring engages the O-ring channel.
-
7. The tool of claim 1 wherein the electrode lead extension is part of a Spinal Cord Stimulation (SCS) system.
-
8. A tool for forming a subcutaneous tunnel, and carrying an electrode lead extension of a Spinal Cord Stimulation (SCS) system back through the tunnel, the tool comprising;
-
a handle;
a rod with a handle end and a carrier end, wherein the handle is attached to the rod at the handle end;
a carrier, wherein the carrier is attached to the rod at the carrier end, and wherein the carrier includes means for tunneling and means for carrying. - View Dependent Claims (9, 10, 11, 12, 13, 14)
a forward carrier end pointed away from the rod;
a rearward carrier end pointed towards the rod;
a carrier body; and
a removable carrier cover;
wherein the carrier cavity is in the carrier body, and wherein the removable carrier cover is removably instalable onto the carrier body by sliding the carrier cover over the forward carrier end of the carrier body, and wherein the means for tunneling comprises a substantially pointed end on the carrier cover pointed away from the rod.

15. A method for making a subcutaneous tunnel and carrying an electrode lead extension through the tunnel, comprising:
-
inserting a tunneling and carrying tool through an incision, which tool comprises means for both creating a tunnel and for carrying an electrode lead extension back through said tunnel;
creating a subcutaneous tunnel by pushing the tool through tissue;
inserting the electrode lead extension into the tool; and
carrying the electrode lead extension to the site of the incision. - View Dependent Claims (16, 17, 18)
removing the carrier cover; and
inserting the lead extension connector into the carrier body.
