The description focuses on electrical stimulation and motion sensing for gait detection, with no mention of AI or ML algorithms for data analysis, decision-making, or adaptation.
Yes
The device is intended to treat foot drop or muscle weakness, facilitate muscle re-education, prevent disuse atrophy, maintain/increase joint range of motion, and increase local blood flow, all of which are therapeutic purposes.
No
The L100 Go System is intended for therapeutic purposes, such as providing ankle dorsiflexion and improving gait, through electrical stimulation. It does not perform any diagnostic functions like measuring, analyzing, or interpreting biological data to identify a disease, condition, or risk.
No
The device description explicitly lists multiple hardware components, including an External Pulse Generator, Lower Leg Cuff, Power supply, Tester, and Electrodes. While it includes software components (Clinician Application and Optional Mobile Application), it is not solely software.
Based on the provided information, the L100 Go System is not an IVD (In Vitro Diagnostic) device.
Here's why:
- IVD devices are used to examine specimens derived from the human body (like blood, urine, tissue) to provide information for diagnosis, monitoring, or screening. The L100 Go System does not interact with or analyze any biological specimens.
- The L100 Go System is a therapeutic device. Its intended use is to provide ankle dorsiflexion through electrical stimulation to improve gait and address muscle weakness. It directly interacts with the patient's body to provide a physical effect.
The description clearly outlines a system that delivers electrical stimulation to the lower leg muscles for therapeutic purposes, which falls outside the definition of an In Vitro Diagnostic device.
N/A
Intended Use / Indications for Use
The L100 Go System is intended to provide ankle dorsiflexion in adults with foot drop or muscle weakness related to upper motor neuron disease/injury (e.g., stroke, damage to the spinal cord). The L100 Go System electrically stimulates muscles in the affected leg to provide ankle dorsiflexion of the foot; thus, it also may improve the adult's gait.
The L100 Go System may also:
- Facilitate muscle re-education
- Prevent/retard disuse atrophy
- Maintain or increase joint range of motion
- Increase local blood flow

Device Description
The L100 Go System is designed to improve gait in adults suffering from foot drop or muscle weakness. The L100 Go System can also deliver transcutaneous stimulation to the muscles in the lower leg to facilitate muscle re-education, prevent/retard disuse atrophy, maintain or increase joint range of motion, and/or increase local blood flow.
The L100 Go system consists of the following L300 Go components/accessories with the exception of a modified lower leg cuff:
- External Pulse Generator (EPG), which can be plugged into Lower Leg Cuff. EPG contains user interface including control and indications. EPG also contains integrated motion sensors enabling detecting gait events.
- Lower Leg Cuff, including cradle for the EPG. This is the only L300 Go component modified for the L100 Go.
- Clinician Application (CAPP), installed on tablet PC. CAPP is used by a trained clinician during configuration of the system for optimal fitting to the patient.
- Power supply (charger) with two USB ports and a proprietary cable to charge the EPG.
- Tester, which is used for trouble shooting to confirm that stimulation is being delivered.
- Optional Mobile Application (MAPP), based on the iOS and Android SmartPhone platform enabling the patients to wirelessly control the EPG(s) and retrieve and monitor their daily activity.
- Electrode and electrode bases which are attached to the inner side of the lower leg cuff.
The L100 Go System can be operated in one of the following modes:
- Gait Mode
- Training Mode
- Clinician Mode
Gait Mode is used for walking, and it can be selected by the clinician and also by the patient. Training Mode is used to train muscles when patients are not walking (for example, sitting or lying down), and it can be selected by either the clinician or the patient. Clinician Mode allows the clinician to apply enhanced training and is only available to the clinicians.

Purpose of this Special 510(k):
This Special 510(k) is submitted for a system called L100 Go System which is the same device as the Lower Leg configuration of the predicate L300 Go System with modified cuff design. None of the modifications affect the intended use of the device nor do they alfer the fundamental scientific technology of the device.
Device Description:
The L100 Go System is designed to improve gait in adults suffering from foot drop or muscle weakness. The L100 Go System can also deliver transcutaneous stimulation to the muscles in the lower leg to facilitate muscle re-education, prevent/retard disuse atrophy, maintain or increase joint range of motion, and/or increase local blood flow.
The L100 Go system consists of the following L300 Go components/accessories with the exception of a modified lower leg cuff:
-
- External Pulse Generator (EPG), which can be plugged into Lower Leg Cuff. EPG contains user interface including control and indications. EPG also contains integrated motion sensors enabling detecting gait events.
-
- Lower Leg Cuff, including cradle for the EPG. This is the only L300 Go component modified for the L100 Go.
-
- Clinician Application (CAPP), installed on tablet PC. CAPP is used by a trained clinician during configuration of the system for optimal fitting to the patient.
-
- Power supply (charger) with two USB ports and a proprietary cable to charge the EPG.
-
- Tester, which is used for trouble shooting to confirm that stimulation is being delivered.
-
- Optional Mobile Application (MAPP), based on the iOS and Android SmartPhone platform enabling the patients to wirelessly control the EPG(s) and retrieve and monitor their daily activity.
-
- Electrode and electrode bases which are attached to the inner side of the lower leg cuff.
The L100 Go System can be operated in one of the following modes:
- Gait Mode
- Training Mode •
- . Clinician Mode
Gait Mode is used for walking, and it can be selected by the clinician and also by the patient. Training Mode is used to train muscles when patients are not walking (for example, sitting or lying down), and it can be selected by either the clinician or the patient. Clinician Mode allows the clinician to apply enhanced training and is only available to the clinicians.

Indications for Use:
The L100 Go System is intended to provide ankle dorsiflexion in adults with foot drop or muscle weakness related to upper motor neuron disease/injury (e.g., stroke, damage to pathways to the spinal cord). The L100 Go System electrically stimulates muscles in the affected leg to provide ankle dorsiflexion of the foot; thus, it also may improve the adult's gait.
The L100 Go System may also:
- Facilitate muscle re-education .
- Prevent/retard disuse atrophy .
- Maintain or increase joint range of motion ●
- Increase local blood flow ●
Modifications Addressed in this Special 510(k)
This Special 510(k) addresses the new L100 Go Cuff which is a modification of the predicate L300 Go lower leg cuffs. The L100 Go Cuff combines the design elements of both the L300 Go lower leg Reqular and Small cuffs.

Table ends here
The difference between the predicate device and the device in this submission is in the number of programs offered, the availability of the optional Control Unit and Foot Sensor, the number of available electrodes, and the weight of the subject device is a simpler system, therefore, the Cycle Training Mode feature is disabled. For the same reason, the optional Control Unit and Foot Sensor that are offered with the predicate device is not offered with the subject device. Furthermore, the subject device, the L100 Go System, is a single channel system, therefore, the steering electrode which is used for 2 channel stimulation is not applicable. These technological differences do not affect the safety and effectiveness of the subject device.
Summary of Nonclinical Tests Submitted
The modified cuff design was subjected to verification testing to ensure no loss of mechanical strength and functionality.
Conclusion:
The L100 Go System has been verified and validated successfully for its intended use through the combination of predicate device bench testing and thorough verification and validation testing of all changes. Based on the result of the nonclinical testing, Bioness concludes that the device is substantially equivalent to the predicate L300 Go System.
