(A) The Altius System is designed to deliver high frequency nerve block (HFNB) pain relief therapy. Foreground: Implantable Pulse Generator (IPG) connected to a single nerve cuff electrode. Background (left to right): Physician Programming Wand, IPG Battery Charger with Charging Pad, Patient Controller. (B) HFNB parameters in lower limb post-amputation subjects are compared to spinal cord stimulation (SCS) parameters used in failed back surgery syndrome (FBSS). The table below (adapted from Billot et al 2020) highlights that HFNB induced by the Altius System – and in direct, circumferential contact with the amputated nerve – provides pain relief that is putatively different than tonic and sub-paraesthetic SCS modalities in FBSS.
