Intended Use
The L-TENS is used for the symptomatic relief and management of chronic intractable pain and/or as an adjunctive treatment in the management of post-surgical and post-traumatic acute pain.
Device Description
The L-TENS is a handheld battery powered TENS device, which is used for pain relief. The device would generate electrical pulses and transmit it to the electrodes, which are attached to the patient's skin. Consequently, the electrical pulses would then pass through the skin to the underlying peripheral nerves to aid in the blocking of pain signals traveling to the brain. L-TENS has one output channel and four preset programs. The program mode is displayed on a LCD. The user can adjust the output intensity by 14 steps.
More Information

No
The description details a standard TENS device with preset programs and adjustable intensity, with no mention of AI or ML capabilities.

Yes
The device is intended for "symptomatic relief and management of chronic intractable pain and/or as an adjunctive treatment in the management of post-surgical and post-traumatic acute pain," which are therapeutic purposes.

No

The device description states its use is for "symptomatic relief and management of chronic intractable pain" and "as an adjunctive treatment in the management of post-surgical and post-traumatic acute pain," which are therapeutic rather than diagnostic purposes. It works by generating electrical pulses to block pain signals, not to detect or identify a medical condition.

No

The device description explicitly states it is a "handheld battery powered TENS device" that "generate[s] electrical pulses and transmit[s] it to the electrodes," indicating it is a hardware device with electrical components.

No, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • IVD Definition: In Vitro Diagnostics are medical devices used to examine specimens taken from the human body (like blood, urine, or tissue) to provide information about a person's health. This includes tests for diagnosing, monitoring, or screening for diseases or conditions.
  • L-TENS Function: The L-TENS device described is a Transcutaneous Electrical Nerve Stimulation (TENS) device. It works by applying electrical pulses to the skin to alleviate pain. It does not analyze any biological specimens from the patient.

The description clearly states its function is to generate electrical pulses and transmit them to electrodes on the patient's skin for pain relief. This is a physical therapy or pain management device, not an in vitro diagnostic device.

10 510(k) Summary

This 510(k) summary of safety and effectiveness information is being submitted in accordance with the requirements of SMDA 1990 and 21 CFR 807.92.

The assigned 510(k) number is: _______________________________________________________________________________________________________________________________________________

10.1 Submitter's Identification

Fuji Dynamics Ltd. Unit 1-3, 23/F., Laws Commercial Plaza, 788 Cheung Sha Wan Road, Kowloon, Hong Kong Tel: (852) 2786 4218 Fax: (852) 2744 6775

Contact Person: Anthony Ah Yin, Shum April 29th 2004 Date Prepared:

10.2 Name of Device:

Proprietary Name:L-TENS
Common or Usual Name:TENS unit
Classification Name:Stimulator, Nerve, Transcutaneous, for Pain Relief
(21 CFR 882.5890)
Device Classification:Class II

10.3 Predicate Device Information:

The L-TENS is equivalent to the FDTENS 2010 (K994266).

10.4 Device Description:

The L-TENS is a handheld battery powered TENS device, which is used for pain relief. The device would generate electrical pulses and transmit it to the electrodes, which are attached to the patient's skin. Consequently, the electrical pulses would then pass through the skin to the underlying peripheral nerves to aid in the blocking of pain signals traveling to the brain.

L-TENS has one output channel and four preset programs. The program mode is displayed on a LCD. The user can adjust the output intensity by 14 steps.

10.5 Intended Use:

TENS is used for the symptomatic relief and management of chronic intractable pain and/or as an adjunctive treatment in the management of post-surgical and post-traumatic acute pain.

10.6 Technological Comparison to Predicate Device:

The L-TENS has basic technological characteristics that are substantially equivalent to the predicate device. Both devices are battery powered and have adjustable output amplitudes. On the contrary, the legally marketed predicate device has dual channels, while L-TENS is a 1-channel device. The only significant technological difference between the two devices is that L-TENS possesses an open-circuit detection feature. It means that L-TENS could check the continuity between the output terminals, and avoid increment of output in the absence of load.

All units use "shrouded patient cable connectors" to comply with the FDA's Final Rule "Mcdical Devices: Establishment of Performance Standards for Electrode Lead Wires and Patient Cables."

10.7 Non-clinical Testing:

Compliance to applicable voluntary standards includes ANSVAAMI NS4-1986, as well as EN 60601-1, EN 60601-1-1 and EN 60601-1-2 requirements.

In addition to the compliance of voluntary standards, the software verification has been carried out according to the FDA software guidance.

10.8 Clinical Testing

Not Applicable as there are no new or innovative aspects that have been introduced.

10.9 Conclusions:

The L-TENS has the same intended use and similar technical characteristics as the FDTENS 2010 (K994266).

The information supplied in this 510(k) illustrates that the device do not pose any new questions of safety and effectiveness. Therefore, the L-TENS is substantially equivalent to the predicate device.
