What is it indicated for?
The StimQ Peripheral Nerve Stimulator (PNS) System is indicated for pain management
in adults who have severe intractable chronic pain of peripheral nerve origin, as the sole
mitigating agent, or as an adjunct to other modes of therapy used in a multidisciplinary
approach. The StimQ PNS System is not intended to treat pain in the craniofacial region.
The StimQ Trial Lead Kit is only used in conjunction with the StimQ Stimulator
Receiver Kit. The trial devices are solely used for trial stimulation (no longer than 30
days) to determine efficacy before recommendation for a permanent (long term) device.
Indications for use as stated in the FDA summary.
