Detailed Description
Chronic pain is managed by the sequential application of various strategies: medications, anesthetic injections, ablation, surgery, implantable intraspinal infusion pumps, and spinal cord stimulation. For a significant number of patients, however, these treatments are inadequate or cannot be tolerated. Those patients require another option for pain relief.
The therapy afforded by spinal cord stimulators is dependent on overlapping paresthesia with the painful areas. One of the leading reasons for explant of SCS systems (not including device failure or surgical complication) is the complaint of inadequate pain relief due to poor coverage of the painful area. Mounting evidence suggests that the clinical efficacy afforded by SCS varies with each manufacturer's technology. For instance, previously-implanted SCS patients report more complete coverage, better pain relief, and a more pleasant sensation associated with the paresthesia of the Precision system. The tight lead spacing and current fractionalization achievable with the Precision system may provide pain relief after failure with another SCS system.
This study will assess pain relief with the Precision system for patients with chronic, intractable pain who are refractory to treatment with other types of SCS systems and/or implantable intraspinal infusion pumps. Because Precision allows unique programming combinations not possible with other systems, it is expected that subjects will enjoy significant pain relief.

Description
Inclusion Criteria:
- Have chronic and intractable neuropathic pain of the trunk and/or limbs of moderate to severe intensity and have failed treatment with an intraspinal infusion pump or other SCS device. Determination of failure of treatment will be based on subject feedback. Subjects with an active intraspinal infusion pump but with inadequate pain control will be allowed to participate;
- Be 18 years of age or older;
- Be an appropriate candidate for the surgical procedures required for this study;
- Be willing and able to comply with all study related procedures and visits;
- Be capable of reading and understanding patient information materials and giving written informed consent.
Exclusion Criteria:
- Have failed immediate past treatment with an intraspinal infusion pump or other SCS device because of technical reasons associated with the device such as unresolved lead migration, battery depletion, etc.;
- Have any evidence of neurologic instability requiring surgery;
- Have any significant medical condition that in the opinion of the investigator may interfere with the conduct of the study or may adversely affect the subject's safety during the study;
- Have any other active implantable device with the exception of a intraspinal infusion pump for pain medications;
- Are pregnant or lactating or planning to become pregnant in the next year;
- Have participated in any investigational drug or device trial in the last 4 weeks or plan to participate in any other investigational drug or device trial while on this study.
