Device Story

Cryocare CN2 System is a cryosurgical console using Near Critical Nitrogen (NCN) as a transition fluid to deliver extreme cold to targeted tissue. System controls up to four single-use disposable Cryoprobes and monitors up to four independent T-type thermocouple TempProbes. Console features high-resolution LCD, video printer, and CD-R/W drive. IBM-compatible microprocessor manages control and monitoring tasks. Operated by physicians in surgical settings. Cryoprobes deliver cold to ablate tissue; warm nitrogen gas is used for thawing. TempProbes provide real-time feedback on surrounding tissue temperatures. Output includes visual monitoring of cryo-process and hard-copy documentation. Enables precise tissue destruction/ablation for various oncological, urological, and dermatological conditions, benefiting patients through minimally invasive surgical options.

#### · Device Description:

The Cryocare CN2 System consists of a compact, easy-to-operate console that delivers cold temperatures to targeted tissue (via connected Cryoprobes) and monitors temperatures in the surrounding tissue (via connected TempProbes). Near Critical Nitrogen (NCN) is utilized as the cryogenic medium. Circulating NCN avoids the 'vapor lock' potential of liquid N2 devices since it is a transition fluid (nitrogen that is neither a liquid, nor a gas).

The Cryocare CN2 System has a fold-down LCD high-resolution display screen, a video printer for hard copy prints of the captured images and patient information, a CD-R/W drive for data storage and retrieval, an alphanumeric keypad and a remote keypad.

The Cryocare CN2 System can control up to four, single-use, disposable Cryoprobes and monitor up to four independent TempProbes. The console operates off standard 120/230 VAC (60/50 Hz) wall power and utilizes inert liquid nitrogen. An IBM compatible microprocessor serves as the host computer which performs all essential controls and monitoring tasks. Cryoprobe control is achieved via the keypad.

Associated accessories include the following:

- 1.) Cryoprobes that deliver cold temperatures to targeted tissue. Each Cryoprobe incorporates a thermocouple to measure internal Cryoprobe temperatures. Warm room

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

temperature nitrogen gas is used after the freezing process to thaw tissue. The patient contact Cryoprobe (an accessory item to the Cryocare CN2 System) is supplied as a Single use Sterile Disposable item. This probe attaches to a reusable Cryo-Hose, which in turn attaches to the Cryocare CN2 System.

- TempProbes to monitor temperatures in the surrounding tissue. The TempProbes are 2.) standard T-type thermocouples.
- 3.) A warming system for use in urological applications.

## · Indications for Use Statement:

The Cryocare CN2 System has the same intended use as previously cleared for the predicate devices.

The Cryocare CN2 System is intended for use in open, minimally invasive or endoscopic surgical procedures in the areas in general surgery, urology, gynecology, oncology, neurology, dermatology, ENT, proctology, pulmonary surgery and thoracic surgery.

- The SAFETY FEATURES of the Cryocare CN2 System, Cryoprobe and Cryo-4. Hose accessory items are the SAME to those offered by the predicate device,

Therefore, in summary, the Cryocare CN2 System, Cryoprobe and Cryo-Hose accessory items are substantially equivalent to the identified predicate device accessory items that have previously been allowed for commercial distribution in the United States.

## · Safety and Effectiveness

The Cryocare CN2 System complies with the ASTM "Standard Performance and Safety Specification for Cryosurgical Medical Instruments" [Designation: F 882-84 and Davy 2002)] which reasonably assures the device is safe when used as directed for its prescribed intended use.

The Cryocare CN2 System does not raise any new issues of safety, effectiveness or performance of the device when compared to the existing predicate device.

## · Conclusions

The data submitted in this 510(k) Premarket Notification, for the Cryocare CN2 System demonstrates that this device and Cryoprobe and Cryo-Hose accessory item is substantially equivalent with respect to the indications for use, operating principles, operational features, and safety features to the identified legally marketed predicate device.
