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.

A system for lead implantation, comprising

a lead comprising
a 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 at the proximal end of the paddle-style electrode, and
at 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 into the longitudinal lumen of the paddle-style electrode, wherein the distal portion of the insertion tool is tapered to narrow a lateral width of the insertion tool along the distal portion, wherein a 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 a 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 a lateral width of the paddle-style electrode.
