Stimwave, founded by former CEO Laura Perryman in 2010, produced a set of implants starting in 2017 meant to use electrical currents near the spine as a nonopioid treatment for chronic pain.
The receiver, referred to as the pink stylet in court documents, was too long to implant in some patients and could not be cut down to size because it would have interfered with the device’s ability to transmit power. The plastic receiver, referred to as the white stylet in court documents, could be cut to size by doctors. This was possible because the white stylet had no copper and therefore no electrical conductivity to be impeded by paring down the receiver in the first place.
