The SPRINT PNS System provides Peripheral Nerve Stimulation (PNS) therapy to relieve pain. In PNS, a lead is placed to target activation of a named peripheral nerve.
Differentiating PNS from PFS, PENS and SCS:
PNS is easily distinguished from other types of stimulation that do not target a named peripheral nerve, such as Peripheral Field Stimulation (PFS), Percutaneous Electrical Nerve Stimulation (PENS) and Spinal Cord Stimulation (SCS).
In PFS, one or more leads are typically placed superficially to target non-specific subcutaneous sensory nerve endings in the region of pain. PFS has also been referred to previously as peripheral nerve field stimulation (PNFS). PFS does NOT deliver the same therapy as PNS.
PENS or electro-acupuncture involves the delivery of electrical impulses through a needle electrode that is inserted just below the skin. Needles are typically removed after each session and re-inserted again at the beginning of the next session. PENS and electro-acupuncture do NOT deliver the same therapy as PNS.
SCS involves the placement of one or more leads adjacent to the spinal cord and generally within the spinal canal or spinal foramen to stimulate the spinal cord rather than peripheral nerves. SCS does NOT deliver the same therapy as PNS.
