1. An electrical lead positioning system comprising:
- an electrical lead positioning tool comprising;
a handle having a proximal end and a distal end; and
a shaft comprising a shaft body extending longitudinally from the handle'"'"'s distal end, the shaft body having a portion thereof comprising a malleable material and a distal portion having a substantially non-cylindrical cross-section;
andan electrical lead comprising;
an electrical elongate lead body having a proximal end and a distal end;
an electrical conductor extending from the proximal end and through the distal end; and
a substantially flat paddle comprising;
a paddle body at the distal end of the lead body, the paddle body having a front side, a back side, a first lateral side, a second lateral side, a proximal end, a distal end, and a length extending between the proximal and distal ends; and
an electrode array comprising an electrode in electrical communication with the electrical conductor, the electrode array located on a portion of the length of the front side of the paddle body.

Abstract
Electrical lead positioning systems, devices, and methods are disclosed. Systems include an implantation tool having a malleable portion to allow a user to customize the configuration of the implantation tool to navigate to the target site of a patient'"'"'s body. Electrical leads are also provided with retention features to secure the implantation tool to the lead during use.
