The LL TENS 160A and LL TENS 160B are 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
LL TENS 160A and LL TENS 160B are handheld battery powered TENS devices for pain relief intended for over-the-counter use. The device would generate electrical pulses and transmit it to the electrodes, which are attached to the patient's (user'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. LL TENS 160A and LL TENS 160B has two output channels and four preset programs. The program mode is displayed on LCD. The user can adjust the output intensity by 14 steps. LL TENS 160A and LL TENS 160B have same hardware, software and mechanical structure. The difference is that LL TENS 160A's LCD display is placed on the bottom of keys while LL TENS 160B's LCD display is on the top of keys. Since the device is battery powered, there is no connection to AC mains supply.
More Information

Not Found

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 used 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 indications.

No

Explanation: The device description states it is a TENS device used for "symptomatic relief and management of chronic intractable pain," and it generates electrical pulses for pain blocking. This indicates a therapeutic, rather than a diagnostic, purpose.

No

The device description explicitly states it is a "handheld battery powered TENS device" that generates electrical pulses and transmits them to electrodes. This indicates a physical hardware component responsible for delivering the therapy, not solely software.

Based on the provided information, the LL TENS 160A and LL TENS 160B devices are not In Vitro Diagnostic (IVD) devices.

Here's why:

  • Intended Use: The intended use is 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." This describes a therapeutic application, not a diagnostic one.
  • Device Description: The device description explains that it generates electrical pulses transmitted to electrodes on the skin to block pain signals. This is a physical intervention, not a test performed on biological samples.
  • Lack of IVD Characteristics: The description does not mention any of the typical characteristics of an IVD device, such as:
    • Analyzing biological samples (blood, urine, tissue, etc.)
    • Detecting or measuring substances in biological samples
    • Providing information for diagnosis, monitoring, or screening of diseases or conditions

In summary, the LL TENS 160A and LL TENS 160B are therapeutic devices used for pain management, not diagnostic devices used for testing biological samples.

DIFFERENCES BETWEEN NEW DEVICE AND PREDICATE DEVICE:

The technical characteristics of LL TENS 160A / LL TENS 160B are similar to those of the predicate devices in design, energy source, intended use and function. Like the predicate device Pain Buddy, the LL TENS 160A / LL TENS 160B is a device used to apply an electrical current to electrodes on a patient's skin to relieve pain.

LL TENS 160A and LL TENS 160B are developed on the similar platform as the predicate device Pain Buddy. On hardware, the schematic and the use of electronics components are similar. The software uses same mechanism as Pain Buddy. Therefore the basic timing, key scanning and generation of pulse are the same.

Some output parameters, including maximum output voltage, maximum output current, phase charge, maximum average current, maximum frequency and pulse duration are different from those of Pain Buddy. However, the maximum phase charge of LL TENS is 18.1uC, which is less than the limit of the safety standard. The Maximum average current is 0.9mA, which is also below the 10mA limit. The maximum average power density is 0.0025 W/cm², which is also less than 0.25W/cm². The maximum frequency of LL TENS is 90Hz. It is slightly higher than those of predicate device and thus does not raise question of safety and effectiveness. Finally, the maximum pulse duration is 208us and higher than of predicate device. Nevertheless, the maximum phase charge of LL TENS is still less than safety limit in this pulse duration. In conclusion, these differences between LL TENS and predicate device do not raise a question in safety and effectiveness.

The LL TENS 160A and LL TENS 160B are views as substantially equivalent to the predicate devices because the electrical stimulation provided by the LL TENS 160A and LL TENS 160B is substantially equivalent to that commonly employed by TENS devices that have been cleared for marketing without prescription labeling, i.e. for OTC use.

The differences between LL TENS and the predicate device do not raise questions on safety and effectiveness. In other word, LL TENS 160A and LL TENS 160B are as safe as the predicate device.

PERFORMANCE TESTS:

The relevant standards including :

IEC 60601-1:2005 + CORR. 1:2006 + CORR. 2:2007 + AM1:2012 Medical Electrical Equipment - Part 1: General requirements for basic safety and essential performance.

IEC 60601-1-2:2007 Medical electrical equipment - Part 1-2: General requirements for basic safety and essential performance. Collateral Standard: Electromagnetic Compatibility. (Edition 3).

IEC 60601-1-11:2010 Medical electrical equipment - Part 1-11 General requirement for basic safety and essential performance - Collateral standard: Requirements for medical electrical equipment and medical electrical systems used in the home healthcare environment.

IEC 60601-1-6:2010 Medical electrical equipment - Part 1-6 General requirements for basic safety and essential performance – Collateral standard: Usability.

USABILITY STUDY:

A usability study has been performed and showed that users were able to use the device correctly and safety.

CONCLUSION:

The electrical stimulation provided by the LL TENS 160A and LL TENS 160B is similar to that commonly employed by TENS devices that have been cleared for marketing without prescription labeling (i.e. OTC).

LL TENS 160A and LL TENS 160B have the same intended use and the same technical characteristics as the OTC cleared predicate device, Pain Buddy [510(k) No.: K102051].

The differences between LLTENS and the predicate device do not raise questions on safety and effectiveness. In other words, LL TENS 160A and LL TENS 160B are as safe as the predicate device.

Thus, the new device LL TENS 160A and LL TENS 160B are substantially equivalent to the predicate device.
