## Indications for Use

The T-Pump Localized Temperature Therapy Pump is intended for use in supplying warm or cold water at controlled temperatures via water circulating pad for the application of localized therapy in situations where a physician determines that temperature therapy is necessary or desirable. Localized temperature therapy is of particular benefit in treating the following; orthopedic conditions such as acute injuries, chronic pain, lower back pain, muscle spasm and strains; skin trauma such as abscesses, boils, bruises, burns and contusions; other medical conditions such as chronic arthritis, neuritis, phlebitis, tendonitis and I.V. infiltration: and symptoms such as infection and localized pain.

## Device Story

T-Pump is an electronically controlled water heater/circulator for localized temperature therapy. Device uses heating element to warm water to user-selected set points via digital interface; cooling achieved by adding ice water to reservoir. Dual microprocessor circuit and thermostat manage temperature range (50°F to 107°F) and prevent overheating. Water circulates through a connector hose to a patient-applied pad. Used in clinical settings; operated by healthcare providers. Provides controlled thermal therapy to treat orthopedic injuries, chronic pain, skin trauma, and inflammatory conditions. Benefits include localized symptom relief and management of specific medical conditions.

## Clinical Evidence

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

## Technological Characteristics

Water circulating pump; ABS plastic and polycarbonate housing; 11.5 x 8 x 8 inches; <10 lbs; 2750ml reservoir capacity. Heating element; dual microprocessor control circuit; thermostat; digital display. Flow rate 9 gph minimum. Leakage current 100 microamperes max. Temperature range 50°F-107°F.

## Regulatory Identification

A water circulating hot or cold pack is a device intended for medical purposes that operates by pumping heated or chilled water through a plastic bag and that provides hot or cold therapy for body surfaces.

## Special Controls

*Classification.* Class II (special controls). The device is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to § 890.9.

## Predicate Devices

# 510(k) SUMMARY

### DATE PREPARED

December 27, 2007

### INTRODUCTION

According to the requirements of 21 CFR 807.92, the following provides sufficient detail to understand the basis for a determination of substantial equivalence.

### CONTACT INFORMATION

Submitter: Gaymar Industries, Inc. 10 Centre Drive Orchard Park, NY 14127 716.662.8636 Contact Person: Greg Pepe Application Correspondent: Hodgson Russ LLP 140 Pearl Street, Suite 100 Buffalo, NY 14202 716.848.1554 Contact Person: Bethany Gilbert, Esq.

#### DEVICE NAME

| Proprietary Name:    | T-Pump Localized Temperature Therapy Pump |
|----------------------|-------------------------------------------|
| Catalog Numbers:     | TP650, TP650C, TP700, TP700C              |
| Common Name:         | Temperature Therapy Pump                  |
| Classification Name: | Pack, Hot or Cold Pack, Water Circulating |

### PREDICATE DEVICE

Gaymar Industries, Inc. ('Gaymar'') claims substantial equivalence to:

- 1. Gaymar Industries, Inc. T-Pump Temperature Therapy Pump (K760804)
- 2. Adroit Medical Systems, Inc. HTP-1500 Localized Heat Therapy Pump (K970197)

### DEVICE DESCRIPTION

The T-Pump Localized Temperature Therapy Pump is a small electronically controlled water heater that supplies warm or cold water at controlled temperatures to a water circulating pad for the application of localized temperature therapy. The control unit is an cloctrical device that uses a heating element to increase the temperature of water to controlled temperature set points,

{1}------------------------------------------------

which the user selects from the digital display face. The temperature is controlled by a dual microprocessor control circuit and a thermostat to prevent overheating. To utilize the cold therapy option, the user adds ice water to the device, which will heat the water to a set point of 50 degrees Fahrenheit. The temperature range of the device ranges from 50 degrees Fahrenheit (for the cooling option) to 107 degrees Fahrenheit (the highest heating set point).

The T-Pump Localized Temperature Therapy Purnp attaches to a connector hose that connects to the water-circulating pad; the temperature-controlled water flows from the pump to the pad. The pads are applied to the part of the body requiring temperature therapy, thereby providing the interface for the therapy.

The T-Pump Localized Temperature Therapy Pump measures, in inches, 11.5 x 8 x 8. The device weighs under 10 pounds with the unit filled with water reservoir has a maximum capacity of 2750ml. The housing is composed of ABS Plastic and Polycarbonate.

The leakage current is 100 microamperes maximum, and the flow rate is 9 gph (34 lph) minimum, with the water circulating pad attached.

### INTENDED USE

The T-Pump Localized Temperature Therapy Pump is intended for use in supplying warm or cold water at controlled temperatures via water circulating pad for the application of localized therapy in situations where a physician determines that temperature therapy is necessary or desirable.

Localized temperature therapy is of particular benefit in treating the following; orthopedic conditions such as acute injuries, chronic pain, lower back pain, muscle spasm and strains; skin trauma such as abscesses, boils, bruises, burns and contusions; other medical conditions such as chronic arthritis, neuritis, phlebitis, tendonitis and I.V. infiltration: and symptoms such as infection and localized pain.

### SUBSTANTIAL EQUIVALENCE

Substantial equivalence is based on two predicate devices.

First, the T-Pump Localized Temperature Therapy Pump is substantially equivalent to the predicate T-Pump Temperature Therapy Pump. Both devices supply warm or cold water to a water-circulating pad for the application of localized heat or cold therapy. None of the device modifications pose risk to safety or effectiveness different from those posed by the predicate T-Pump Temperature Therapy Pump.

Second, the T-Pump Localized Temperature Therapy Pump is substantially equivalent to the predicate Adroit HTP 1500 Localized Heat Therapy Pump. Both devices use a digital interface and software to control the temperature of the circulating water. None of the device

{2}------------------------------------------------

modifications pose a risk to safety or effectiveness different from those posed by the predicate Adroit HTP 1500 Localized Heat Therapy Pump.
