APPARATUS FOR SUBCUTANEOUS ELECTRODE INSERTION
First Claim
1. A tool for inserting a lead electrode assembly subcutaneously, the tool comprising:
- a handle; and
a shaft having a proximal end and a distal end, the shaft being secured near its proximal end to the handle and including an attachment feature near its distal end for attaching to a lead electrode assembly, the distal end being shaped for advancement through tissue;
wherein;
the shaft further defines a lumen extending therein to a distal infusion port;
the attachment feature is a suture hole adapted to receive a suture therethrough and configured to allow a suture to be used to secure the tool to a lead for insertion of the lead into the body of a patient; and
the distal infusion port opens into the suture hole.

Abstract
Devices and methods for electrode implantation. A first embodiment includes an electrode insertion tool adapted to tunnel through tissue and attach, at its distal end, to a lead, such that the lead may be pulled into the tunneled space as the electrode insertion tool is removed. Additional embodiments include methods for inserting electrode/lead assemblies, including a method wherein an insertion tool is first used to tunnel through tissue, then to pull an electrode/lead into the tunneled space. In a further embodiment the insertion tool is next used, with a splittable sheath disposed thereon, to create an additional path into tissue, after which the insertion tool is removed, leaving the sheath in place; a lead is inserted to the sheath, and, finally, the splittable sheath is removed over the lead.
