## Indications for Use

The P-Stim is intended for use as an electro-acupuncture device to stimulate appropriate auricular acupuncture points.

## Device Story

P-Stim is a miniaturized, battery-powered, transcutaneous electrical nerve stimulator (TENS) for auricular acupuncture. Device connects via three stainless steel wires to acupuncture needles inserted into auricular points. Operates on a pre-programmed cycle: 180 minutes on, 180 minutes off, for up to 96 hours. Powered by three 1.4V zinc air batteries. Used by qualified acupuncture practitioners to provide electrical stimulation to acupuncture points. Output parameters (frequency, pulse, duration) are pre-programmed. Intended to assist in acupuncture therapy.

## Clinical Evidence

No clinical data provided; substantial equivalence based on technological characteristics and intended use.

## Technological Characteristics

Miniaturized, battery-powered TENS device. Power source: three 1.4V zinc air batteries. Output: single channel, pre-programmed frequency, pulse, and duration. Interface: three stainless steel wires connecting to acupuncture needles. Conductive gel used at electrode-skin interface. Non-sterile components (needles applied by practitioner).

#### Predicate Device

The legally marketed predicate device to which the P-Stim is substantially equivalent is the Acu-Stim (K014273).

#### Intended Use

The P-Stim is intended for use as an electro-acupuncture device to stimulate appropriate auricular acupuncture points.

#### Device Description

The P-Stim is a miniaturized, battery-powered, transcutaneous electrical nerve stimulator that has a pre-programmed frequency, pulse, and duration for the stimulation of auricular acupuncture points. The device connects via three stainless steel wires to acupuncture needles that have been applied to the appropriate auricular acupuncture points. The device is powered by three zinc air batteries, each with a voltage of 1.4 V. The device is on for 180 minutes, then off for 180 minutes, for a maximum period of up to 96 hours.

# Summary of Technological Characteristics

Substantial equivalence is claimed because the P-Stim has the same intended use and similar operating principles to the Acu-Stim. Both devices are transcutaneous electrical nerve stimulators with a single output channel and mode and similar pulse widths and frequencies. Both use a conductive gel between the electrode and the patient's skin. Technical differences do not affect the safety or efficacy of the product.

Dear Dr. McComb:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.
