Patent number: 9962543Abstract: In some embodiments, a paddle lead is implanted within a patient such that the electrodes are positioned within the cervical or thoracic spinal levels. An electrode combination on a first row of electrodes can be determined that is effective for a first pain location with minimal effects on other regions of the body. The first pain location can be addressed by stimulating a first dorsal column fiber due to the relatively fine electrical field resolution achievable by the multiple columns. Then, another electrode combination on a second row of electrodes can be determined for a second pain location with minimal effects on other regions. The second pain location could be addressed by stimulating a second dorsal column fiber. After the determination of the appropriate electrodes for stimulation, the patient's IPG can be programmed to deliver pulses using the first and second rows according to the determined electrode combinations.Type: GrantFiled: November 20, 2013Date of Patent: May 8, 2018Assignee: Advanced Neuromodulation Systems, Inc.Inventors: Claudio A.
