Device Description

The PM710 is a wearable electrotherapy device that is designed to alleviate chronic, acute and arthritic muscle leg pain. It delivers TENS (Transcutaneous Electrical Nerve Stimulation) technology through the simple, convenient control on the main unit. The reusable, self-adhesive contouring pads allow for discreet and convenient placement on the pain locations below the knee. The device contains one main TENS unit which is rechargeable and can be attached to a single sized gel and a medium or large band (model number follow by "-M" / "-L") which helps to attach the device to the leg. The pad with attached TENS unit can then be applied to intact skin at the desired location below the knee for therapy and pain relief. Control of the PM710 TENS system is through the control buttons on the main unit and the intensity of the therapy is displayed by the Intensity Level Indicators during treatment. The PM710 will be packaged with an Instruction Manual which provides details on setting up the device for use, setting and controlling intensity levels, and troubleshooting. The system accessories include one charger, one AC adapter for the charger, and one pad holder and storage case.

AI/ML Overview

Here's a summary of the acceptance criteria and study information for the Omron Focus TENS Therapy, Model PM710-M/-L, based on the provided FDA 510(k) submission.

1. Table of Acceptance Criteria and Reported Device Performance

The submission does not present a formal table of "acceptance criteria" against which a clinical study's performance metrics are directly compared. Instead, it demonstrates substantial equivalence through extensive non-clinical testing and comparison of technological characteristics with predicate and reference devices. The "performance data" provided refers exclusively to these non-clinical tests.

However, based on the comparison tables, we can infer some "performance criteria" that the device implicitly meets by matching or being within acceptable ranges of the predicate and reference devices.

PREDICATE DEVICE(S) [807.92(a)(3)]

The Omron Focus TENS Model PM710-M/-L ("PM710") is substantially equivalent to the predicate device, the Omron Avail Wireless Dual Channel TENS PM601 (K172079), with regard to product labeling, intended use, anatomical sites, patient population, performance testing, technological characteristics and safety characteristics. In addition, the PM710 device is also similar to two other reference devices, the Neurometrix, Inc. Quell (K152954) and the Shenzhen Roundwhale Technology Co., Ltd Model R-T1 TENS stimulator (K180956) in regard to intended use and features.

DEVICE DESCRIPTION [807.92(a)(4)]

The PM710 is a wearable electrotherapy device that is designed to alleviate chronic, acute and arthritic muscle leg pain. It delivers TENS (Transcutaneous Electrical Nerve Stimulation) technology through the simple, convenient control on the main unit. The reusable, self-adhesive contouring pads allow for discreet and convenient placement on the pain locations below the knee.

The device contains one main TENS unit which is rechargeable and can be attached to a single sized gel and a medium or large band (model number follow by "-M" / "-L") which helps to attach the device to the leg. The pad with attached TENS unit can then be applied to intact skin at the desired location below the knee for therapy and pain relief. Control of the PM710 TENS system is through the control buttons on the main unit and the intensity of the therapy is displayed by the Intensity Level Indicators during treatment. The PM710 will be packaged with an Instruction Manual which provides details on setting up the device for use, setting and controlling intensity levels, and troubleshooting. The system accessories include one charger, one AC adapter for the charger, and one pad holder and storage case.

INDICATIONS FOR USE [807.92(a)(5)]

The device is intended for the relief of pain associated with sore or aching muscles of the lower extremities (leg) due to strain from exercise or normal household work activities.

It is also intended for the use of symptomatic relief and management of chronic, intractable pain associated with arthritis.

Environments of Use: Clinics, hospital and home environments.

Patient Population: Adult.

COMPARISON OF TECHNOLOGICAL CHARACTERISTICS WITH THE PREDICATE DEVICES [807.92(a)(6)]

In regard to technological characteristics, the PM710 device is similar to the predicate Avail TENS devices in respect to the intended use and indication for use. PM710 is specifically intended for relieving pain of sore or aching muscles of the leg, whereas the Avail device is intended to relieve pain with sore or aching muscles for a wider range of body sites including the lower back, arms, legs, shoulders or feet. Both PM710 and Avail are also intended for the use of symptomatic relief and management of chronic, intractable pain associated with arthritis, and can be used in clinics, hospitals and home for adults.

{5}------------------------------------------------

510(k) SUMMARY (CONT.)

The PM710 device offers one TENS treatment mode similar to the reference device Quell, whereas the predicate Avail device offers nine TENS treatment modes and one microcurrent mode. The waveform generated by PM710 is also different from the waveforms of the Avail system, however the electrical parameters of both are very similar. As such, the waveforms produced by PM710 and Avail can both achieve the same therapeutic outcome of "symptomatic relief and management of chronic, intractable pain as well as the discomfort associated with arthritis". This is due to the presence of:

  • o High frequency (50+) Hz for chronic pain that requires non-contracting stimulation modes for a comfortable smoother therapy for chronic pain therapy.
  • Modulation via different pulse trains to prevent muscle accommodation for both . chronic pain and arthritis.
  • Variation of both high and low rate pulses within the mode to address both muscle o and joint pain from arthritis and various chronic pain.

The composite action of the low and high rate Hz stimulation produces rhythmic muscle contractions which then produces improved local blood vessel vasodilation thus reducing edema and retained metabolites commonly occurring from excessive muscle strain to support weak/arthritic joints. In addition, it enhances the supply of fresh oxygen and nutrients that can further result in decreased discomfort.

In regard to other output characteristics, summary tables of output parameters for the PM710, predicate and reference devices are provided in this submission. In general, the PM710 output parameters fall within the range of output parameters for the predicate Avail device. For example, the maximum current density (mA/cm2) range for PM710 is 0.97, while the Avail is 0.0008 ~ 0.17 which are both well below the IEC60601-2-10:2012 (Clause 201.4.2) limit of less than 2mA/cm². The maximum average power density (W/cm²) range is 7.59x103 for PM710, whereas the Avail maximum average power density range is 1.4x10-8 ~ 6.8x10-4, and the reference device R-T1 TENS is 1.08x10-4~1.48x10-2, which has a closer match to PM710.

In regard to treatment duration, the PM710 offers a specified timer duration for 30 minutes. For Avail, there are two selectable time ranges for TENS therapy; 5 to 60 minutes and 30 to180 minutes, depending on the selected mode. The same time duration of 30 minutes is also offered by the reference device of R-T1. In this regard, PM710 should be considered at least as the predicate and reference devices. A comparison of the PM710 output specification to the predicate device Avail and reference device R-T1 TENS are also provided in this submission.

SUBSTANTIAL EQUIVALENCE

The proposed device, predicate device and reference devices are all intended for use as transcutaneous electrical nerve stimulation in adult populations for use in clinic, hospital or home settings. Omron has completed comprehensive design verification testing, electrical safety and electromagnetic compatibility testing, software verification and validation, and usability testing to ensure that the PM710 device performs as intended. The PM710 also passed testing requirements for electrical safety and EMC, and the device patient-contacting were tested to demonstrate biocompatibility. The minor differences in labeling and technological characteristics between the proposed device and the predicate device have been evaluated and determined to not raise different questions
