What is the Nalu System?

The Nalu System is a drug-free, minimally invasive therapy that delivers gentle electrical stimulation to peripheral nerves to interrupt pain signals.18 The system is designed to provide a personalized, long-term treatment that integrates comfortably into the lives of patients struggling with chronic focal neuropathic pain.

Components of the Nalu System

Nalu micro-Implantable Pulse Generator (mIPG).

A micro-Implantable Pulse Generator (mIPG) that delivers stimulation

Nalu therapy disc.

Externally worn “Therapy Disc” that wirelessly powers the system

Nalu tined and non-tined leads.

Implanted, flexible leads for targeted nerve stimulation

Nalu adhesive clip.

Comfortable wearables designed to maintain secure placement of the Therapy Disc

Nalu patient remote controller.

A patient Remote Control app for minor therapy adjustments

Why choose the Nalu System

Advanced programming capabilities that enable sophisticated therapy customization

Real-time bi-directional (two-way) communication between the mIPG and Therapy Disc to ensure reliable therapy delivery

A discreet wearable designed without external leads or wires for comfortable wear under clothing and therapy delivery only when needed

Miniaturized, implanted components that allow for a streamlined, minimally invasive outpatient procedure designed for rapid recovery

Level 1 clinical evidence that supports sustained pain relief across four anatomical regions and clinically meaningful functional improvements over 24 months19,20

Discover the clinical evidence

The Nalu System is supported by a robust collection of peer-reviewed, published clinical evidence demonstrating sustained pain relief and clinically meaningful functional improvements in clinical trials and real-world application. 

The Nalu System has demonstrated sustained pain relief across 4 anatomical regions and clinically meaningful functional improvements over 24 months.19
