Implantable lead with tethers
First Claim
1. An implantable lead for electrical stimulation of a spinal cord, comprising:
- a paddle sized to be positioned in the epidural space of the spinal canal and having a surface, a first and a second end, and a length that spans one vertebral level of the spinal cord;
an electrode array positioned and arranged on the surface of the paddle, the electrode array comprising at least one electrode contact configured to communicate with a corresponding electrode and a conductor; and
at least one tether having a portion that is connected to the paddle and an end that extends from and is unattached to one of the ends of the paddle, wherein the tether is configured to pull the paddle into the epidural space and secure the implantable lead in place.

Abstract
An implantable lead for electrical stimulation of a spinal cord is disclosed. The implantable lead has a paddle having a surface and a first and a second end, an electrode array positioned and arranged on the surface of the paddle, and at least one tether having an end that extends from one of the first and the second end of the paddle. The electrode array has at least one electrode contact configured to communicate with a corresponding electrode and a conductor. The implantable lead may be included in a kit that also has a securing device and instructions for implanting the implantable lead into the spinal cord. A method of making the implantable lead configured for electric stimulation of a spinal cord is also disclosed. A method of implanting the implantable lead in a spinal canal is also disclosed.
