Neuro-stimulation and ablation system
First Claim
1. A method for treating chronic pain comprising:
- a. providing an implantable lead having an electrode configured to deliver electrical stimulation and ablation energy to a treatment location of a spinal cord of a patient;
b. inserting the lead percutaneously into an epidural space of the spinal cord of the patient;
c. locating the treatment location on the spinal cord by;
i. sending electrical stimulation through the lead to the electrode; and
ii. probing with the lead in the epidural space until the electrode reaches the treatment location on the patient'"'"'s spinal cord where the patient experiences a physiological reaction from the electrical stimulation indicative of the electrode contacting the treatment location; and
d. delivering ablation energy to the electrode to ablate nerve tissue proximate the treatment location.

Abstract
The invention provides a system for treating chronic pain including a lead configured and adapted to be percutaneously implanted into an epidural space of a spinal cord, a stimulation generator that delivers electrical stimulation to the spinal cord through the lead to precisely locate the treatment area, and an ablation generator that delivers ablation energy to the treatment area through the same lead to inhibit the chronic pain. The invention also provides a method for treating chronic pain, including providing a lead, inserting the lead percutaneously into the epidural space, locating the treatment area by probing the epidural space while the lead sends electrical stimulation signals, and then ablating the treatment area.
