Curonix (formerly Bioness) is a medical device company developing the StimRouter Neuromodulation System, an implantable peripheral nerve stimulation device for chronic pain. The StimRouter consists of an ultra-thin, implantable lead placed near a peripheral nerve using a simple injection-like procedure, wirelessly recharged and programmed through an external pulse transmitter that the patient wears over the implant site.

The external wireless powering architecture eliminates the need for a separate implantable pulse generator, reducing the implant to a single minimally invasive component. Patients wear the external transmitter for 1–2 hours per day and remove it during normal activities, providing on-demand therapy without continuous device wear.

The StimRouter system is FDA-cleared and has evidence across back, knee, shoulder, and headache pain indications. Curonix rebranded from Bioness and refocused the portfolio around StimRouter following strategic restructuring.
