Nalu Medical provides a battery‑free neurostimulation system for chronic peripheral nerve pain, consisting of a subcutaneous microstimulator and a wearable therapy disc that wirelessly delivers and programs low‑amplitude electrical pulses. The modular design enables precise nerve targeting, real‑time parameter adjustment, and firmware upgrades without additional surgery, and the implant can be removed in a minor outpatient procedure.

Problem
Patients with intractable chronic peripheral nerve pain have limited therapeutic options; conventional neurostimulation implants are bulky, require implanted batteries, and often need surgical revisions for upgrades or battery replacement. These constraints reduce patient comfort, increase procedural risk, and limit long‑term treatment flexibility.
Solution
Nalu Medical offers a non‑integrated neurostimulation system that separates the implanted microstimulator and electrode array from an externally worn therapy disc. The microstimulator, implanted subcutaneously, delivers precise, low‑amplitude electrical pulses that interrupt nociceptive signaling without pharmacologic intervention. Power and control are supplied wirelessly from the therapy disc, eliminating the need for an internal battery and associated replacement surgeries. The modular architecture enables clinicians to upgrade stimulation protocols via software updates to the disc, extending device longevity and adapting to evolving clinical evidence. Because the system is fully reversible, the implant can be explanted without extensive surgery if therapy is discontinued. This approach provides a discreet, minimally invasive, and drug‑free solution for chronic nerve pain management.
Target Audience
The primary customers are pain‑management physicians, neurologists, and spine surgeons treating patients with chronic peripheral nerve pain who have not responded to medication or conventional therapies. It also serves the patients themselves, offering a discreet, minimally invasive, and drug‑free alternative for long‑term pain control.
Features
- Implantable microstimulator up to 27× smaller than traditional IPGs, reducing tissue footprint and visibility under the skin
- Battery‑free operation powered by a wearable therapy disc that transmits energy and programming commands via inductive coupling
- Separate electrode array optimized for peripheral nerve targeting, allowing precise field shaping and selective fiber activation
- Wireless telemetry enables real‑time programming, parameter adjustment, and therapy monitoring through a clinician‑facing console
- Firmware‑upgradable therapy disc supports new stimulation waveforms and protocols without additional surgery
- Fully reversible implantation; the microstimulator can be removed in a minor outpatient procedure if therapy is stopped
- Compliance with FDA and CE regulatory standards, with encrypted data transmission to meet HIPAA security requirements
- Integrated safety algorithms that automatically suspend stimulation on detection of abnormal impedance or device malfunction
