Device Story

Artrocool®-S is a water-circulating cryotherapy device consisting of an insulated chest, a DC electric pump, and tubing connected to body cuffs. User freezes a water-filled cartridge, places it in the chest, and fills the reservoir with a 4:1 water-alcohol mixture. The pump circulates chilled fluid through the cuff applied to injured or post-surgical body structures. Used in clinical or home settings to provide 6-8 hours of continuous cold therapy for trauma, orthopaedic surgery, sports injuries, and rehabilitation. Healthcare providers or patients use the device to manage pain and swelling; output is the physical application of cold therapy to the patient's skin.

Clinical Evidence

No clinical data provided. Substantial equivalence is based on bench testing and comparative performance specifications (cooling time, temperature range, electrical safety, and design features).

Technological Characteristics

System includes insulated chest, DC electric pump, and fluid cuffs. Operates on 6 VDC power (from 115/230 VAC). Recirculating fluid is 4:1 water/alcohol mixture. Cooling provided by frozen water cartridge. Electrical safety compliant with UL-544; ground leakage current <55 micro-amps. Non-sterile; surface disinfection only.

Indications for Use

Indicated for treatment of pain and swelling of acute periarticular processes, pain and swelling following mobilization of shoulder stiffness under anesthesia, pain and swelling postoperatively for bones, joints and soft tissue, and pain and swelling caused by musculoskeletal contusions and athletic injury.

Regulatory Classification

7. Device Description:

The Artrocool®-S is a typical cold liquid recirculating cryotherapy device. The Artrocool®-S is an insulated ice chest-like box with a closed loop liquid recirculating pump and tubing. The tubing connects to a variety of cuffs designed to be placed on or around injured or post surgical body structures, limbs or joints. The device operates by the use of a water filled cartridge and an insulated chest. The water filled bottle is frozen solid prior to first use. When the bottle is frozen, it is placed within the insulated chamber of the Artrocool. A 4:1 mixture of water and alcohol is poured into the fluid reservoir (balancing container) until full. The pump is circulated with the connecting tubing and cuff attached. Once both are filled and all air bubbles have been purged from the system the unit is ready for service.

8. Substantially Equivalent Device(s):

The Artrocool®-S is substantially equivalent to the Theracool™ Water Circulating Cold Pack, the Polar Care™ Water Circulating Cold Pack, the Dr. Kool™ Water Circulating Cold Pack and the Cryo Cuff™ Water Circulating Cold Pack.

9. Comparison to Predicate Device(s):

With the exception of the Cryo Cuff™ which is a gravity flow device, the Artrocool®-S and the remaining cold therapy units utilize a small DC electric pump to circulate and recirculate a chilled fluid through an assortment of body contact pads or cuffs. All of the powered units including the Artrocool®-S are UL-544 compliant. The water circulating electric pump has a ground current leakage value of less than 55 micro-amps.

None of the units depend on direct refrigeration of the circulating liquid. The Dr. Kool™ and the Artrocool®-S utilize a container of frozen water or chemical gel to cool the isolated recirculating liquid. The rest of the units circulate melt water throughout the system.

The intended uses of all of the units are essentially the same and include conditions like trauma, orthopaedic surgery, sports medicine injuries and rehabilitation, rheumatology, general, plastic and reconstructive surgery, chirosurgery and neurology. All the devices are suitable for any traumatic, medical or surgical conditions benefiting from cold therapy.

The duration of therapeutic cold conditions for all of the units is variable depending on issues like pad/cuff size, ambient temperature, patient temperature, etc. Time duration of useful cold therapy for the comparison units is from 1 ½ to 10 hours. The Artrocool®-S provides cooling for 6 to 8 hours of continuous use.

10. Packaging:

Standard, paper fiber industry typical bulk shipper packaging is utilized. The packaging selected for use is sufficient to identify, protect and transport the device safely.

11. Sterilization/Re-sterilization:

May not be sterilized or re-sterilized. Surface disinfection is possible using commercially available non-solvent based disinfectant products. Cleaning and sanitizing instructions are supplied with each Artrocool®-S unit.

Dear Mr. Schlerf:

We have reviewed your Section 510(k) notifications of intent to market the devices referenced above and we have determined these devices are substantially equivalent (for the indications for use stated in the enclosures) to 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). You may, therefore, market the devices, 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 devices are classified (see above) into either class II (Special Controls) or class III (Premarket Approval), they may be subject to such additional controls. Existing major regulations affecting your devices can be found in the Code of Federal Regulations, Title 21, Parts 800 to 895. A substantially equivalent determination assumes compliance with the current Good Manufacturing Practice requirement, as set forth in the Quality System Regulation (QS) for Medical Devices: General regulation (21 CFR Part 820) and that, through periodic (QS) inspections, the Food and Drug Administration (FDA) will verify such assumptions. Failure to comply with the GMP regulation may result in regulatory action. In addition, FDA may publish further announcements concerning your devices in the Federal Register.
