Our Technology

The Freedom® Peripheral Nerve Stimulator (PNS) System is indicated for pain management in adults with severe, intractable chronic pain of peripheral nerve origin, as the sole mitigating agent, or as an adjunct to other modalities of therapy used in a multidisciplinary approach. The Freedom PNS System is not intended to treat pain in the craniofacial region.

Freedom PNS System

The system uses High Frequency-Electromagnetic Coupling (HF-EMC) technology to power the implanted neurostimulator.
  • Each stimulator comprises of an electrode array(s) with four or eight contacts, and the electrode array(s) is connected to a separate implanted receiver(s).
  • A small, external rechargeable transmitter supplies the power and data to the implanted neurostimulator through the skin.
  • The device uses pulsed electric current to create an electrical field that acts on nerves to inhibit the transmission of pain signals to the brain.

PNS Wearables

The wearables are purposefully designed to work with the Freedom PNS System for any extremity or trunk nerve approach.

The HF-EMC Technology powers the device through clothing*, offering patients a comfortable and discreet option for holding their external transmitter during daily activity.

Patient Selection

Commonly, patients will present with the following conditions and/or medical history:
  • Post-Surgical Chronic Pain
  • Successful Nerve Block
  • Mononeuropathies
  • Successful RFAs
  • High MRI Burden
  • Failed SCS
  • Blood Thinner Dependent
  • Comorbidities

If the Freedom PNS System is right for your patient, they will first undergo a trial period to assess the effectiveness of chronic pain management before transitioning to a permanent implant.

Clinical Evidence

Decrease in Medication Usage
Patients reduced medication usage by 47% at 24 months post-implant. 1
Reduced Pain
Patients reported more than a 70% improvement in pain at all follow-ups. 1
Foot and Ankle patients experienced a 65% reduction in pain scores at 12 months post-implant. 2
Improvement in Quality of Life
Foot and Ankle patients experienced an improvement in quality of life 12 months following PNS implantation. 2
