Insertion tool for paddle-style electrode
First Claim
1. A system for lead implantation, comprisinga lead comprisinga paddle-style electrode extending from a proximal end to a distal end, the paddle-style electrode, comprising a back surface;
- an active surface;
a plurality of electrode contacts disposed on the active surface; and
a longitudinal lumen extending into the paddle-style electrode and defining an opening to an exterior of the lead at the proximal end of the paddle-style electrode, andat least one lead body extending from the paddle-style electrode, the at least one lead body comprising a plurality of conductors that are electrically coupled to the plurality of electrode contacts; and
an insertion tool having a distal portion configured and arranged for insertion of the distal portion of the insertion tool through the opening and into the longitudinal lumen of the paddle-style electrode, wherein at least the distal portion of the insertion tool comprises a low friction material forming a surface of the distal portion of the insertion tool with a coefficient of friction of 0.1 or less, wherein the distal portion of the insertion tool is tapered to narrow a lateral width of the insertion tool along the distal portion, wherein the lateral width of the insertion tool at a proximal end of the distal portion of the insertion tool is at least one half of a lateral width of the paddle-style electrode and the lateral width of the insertion tool at a distal end of the distal portion of the insertion tool is no more than one quarter of the lateral width of the paddle-style electrode.

Abstract
A system for lead implantation includes a lead having a paddle-style electrode extending from a proximal end to a distal end, the paddle-style electrode, having a back surface; an active surface; a plurality of electrode contacts disposed on the active surface; and a longitudinal lumen extending into the paddle-style electrode and defining an opening at the proximal end of the paddle-style electrode. The lead also has at least one lead body extending from the paddle-style electrode. The at least one lead body includes conductors that are electrically coupled to the electrode contracts. The system also includes an insertion tool having a distal portion for insertion into the longitudinal lumen of the paddle-style electrode. At least the distal portion of the insertion tool or the longitudinal lumen (or both) includes a low friction material forming a surface with a coefficient of friction of 0.1 or less.
