Device Story

CMS AccuProbe® (Models 450, 550/530, 600) are cryosurgical units utilizing liquid nitrogen as a cryogen. Systems consist of a console with multiple ports supporting spray or closed probes. Operated by physicians in clinical settings to achieve tissue ablation via extreme cold. Device delivers cryogen to target site; freezing causes cellular destruction of malignant or benign tissue. Output is physical tissue necrosis; healthcare providers monitor procedure to control depth/extent of ablation. Benefits include minimally invasive destruction of lesions, tumors, or arrhythmic cardiac tissue.

Clinical Evidence

No clinical data provided. Substantial equivalence is based on comparison of intended use, technological characteristics, and design to legally marketed predicate devices.

Technological Characteristics

Cryosurgical console system; liquid nitrogen cryogen; multiple ports; spray and closed probe configurations. Class II device per 21 CFR 878.4350(a).

Indications for Use

Indicated for patients requiring cryoablation of benign or malignant tissues across urology (prostate cancer, BPH), oncology (tumors), dermatology (skin cancers, cutaneous disorders), gynecology (genital neoplasia/dysplasia), general surgery (various lesions, warts, cysts, hemorrhoids), thoracic surgery (arrhythmic cardiac tissue, cancerous lesions), and proctology (anal/rectal growths, hemorrhoids). Prescription use only.

Dear Dr. Reinhart:

We have reviewed your Section 510(k) notification of intent to market the devices referenced above and we have determined the devices are substantially equivalent (for the indications for use stated in the enclosure) 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.

Please be advised that this substantial equivalence determination does not include an indication for cryoablation of the endometrium. The use of cryosurgery for endometrial ablation raises new types of safety and effectiveness questions when compared to currently identified predicate devices used for this purpose and therefore will require submission of a premarket approval application (PMA) to market for this indication.

Since, no data has been developed to establish the safety and effectiveness of this cryosurgical device for endometrial ablation, you may not market or promote such use until you have submitted such data and received clearance or approval for this claim.

#### Page 2 - Richard J. Reinhart, Ph.D.

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 requirements , as set forth in the Quality System Regulation (QS) for Medical Devices: General regulation (21 CFR Part 820) and that, through periodic (OS) inspections, the Food and Drug Administration (FDA) will verify such assumptions. In addition, FDA may publish further announcements concerning your devices in the Federal Register. Please note: this response to your premarket notification submissions does not affect any obligation you might have under sections 531 through 542 of the Act for devices under the Electronic Product Radiation Control provisions, or other Federal laws or regulations.

This letter will allow you to begin marketing your devices as described in your 510(k) premarket notification. The FDA finding of substantial equivalence of your devices to a legally marketed predicate device results in a classification for your devices and thus, permits your devices to proceed to the market.

If you desire specific advice for your devices on our labeling regulation (21 CFR Part 801 and additionally 809.10 for in vitro diagnostic devices), please contact the Office of Compliance at [phone]. Additionally, for questions on the promotion and advertising of your devices, please contact the Office of Compliance at [phone]. Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21 CFR 807.97). Other general information on your responsibilities under the Act may be obtained from the Division of Small Manufacturers Assistance at its toll-free number [phone] or [phone] or at its internet address "http://www.fda.gov/cdrh/dsmamain.html".
