Intended Use

The L300 Go System is intended to provide ankle dorsiflexion in adult and pediatric individuals with foot drop and/or assist knee flexion or extension in adult individuals with muscle weakness related to upper motor neuron disease/injury (e.g., stroke, damage to pathways to the spinal cord). The L300 Go System electrically stimulates muscles in the affected leg to provide ankle dorsiflexion of the flexion or extension: thus, it also may improve the individual's gait. The L300 Go System may also: Facilitate muscle re-education Prevent/retard disuse atrophy Maintain or increase joint range of motion Increase local blood flow

Device Story

L300 Go System is an external functional neuromuscular stimulator for gait improvement and muscle rehabilitation. System components: functional stimulation cuffs (lower leg/thigh) with surface electrodes; external pulse generators (EPG); control unit; optional gait sensor; clinician programming software. Input: motion sensor data (lower leg EPG) or gait sensor data (heel events) to trigger stimulation. Operation: EPG delivers biphasic electrical stimulation to muscles to facilitate dorsiflexion or knee flexion/extension. Used in clinics (clinician configuration) and by patients (daily use). Clinician uses tablet/PC software to program stimulation parameters. Patient uses control unit or stimulator-based interface to manage settings and monitor status. Benefits: improved gait, muscle re-education, prevention of disuse atrophy, maintenance of joint range of motion, increased local blood flow.

Clinical Evidence

No clinical data provided; substantial equivalence is based on technological characteristics and bench testing.

Technological Characteristics

External functional neuromuscular stimulator. Materials: Bay State Polymer PA-2000RX (remote/EPG), biocompatible fabric over POM Hi plastic skeleton (lower leg cuff), TPU (thigh cuff), ABS (foot sensor). Energy: Battery-operated. Connectivity: Bluetooth Low Energy. Stimulation: Biphasic symmetric/asymmetric waveforms, current-regulated, 1-2 channels. Standards: IEC 60601-1, IEC 60601-1-2, IEC 60601-2-10, FCC Part 15.

Indications for Use

Indicated for adult and pediatric individuals with foot drop (ankle dorsiflexion) and/or adult individuals with muscle weakness related to upper motor neuron disease/injury (knee flexion/extension).

Regulatory Classification

Identification

An external functional neuromuscular stimulator is an electrical stimulator that uses external electrodes for stimulating muscles in the leg and ankle of partially paralyzed patients (e.g., after stroke) to provide flexion of the foot and thus improve the patient's gait.
