Intended Use

The device is used to destroy unwanted tissue by application of extreme cold to the selected site.

Device Story

Cryosurgical unit utilizing liquid nitrogen (LN2) to destroy unwanted tissue via extreme cold. System comprises console with LN2 dewars and 1-8 interchangeable cryoprobes. Physician positions probe using ultrasound or other imaging; LN2 forced through probe under pressure to freeze target tissue. Procedure monitored via real-time imaging. Post-freeze, warm nitrogen gas heats probe to facilitate thawing and removal. Optional on-board computer provides redundant display and procedure data archival; does not control or affect cryoprobe operation. Used in clinical settings by physicians.

Clinical Evidence

No clinical data provided; substantial equivalence based on design comparison and technological similarity to the predicate device.

Technological Characteristics

Cryosurgical unit; uses liquid nitrogen (LN2) as refrigerant. Console-based system with interchangeable cryoprobes of varying materials/sizes. Operating pressure 65 psi. Features internal nitrogen gas generation. Optional on-board computer for display/archival. Class II device per 21 CFR 878.4350(a).

Indications for Use

Indicated for the destruction of unwanted tissue in patients where surgical resection is not possible or as an alternative to typical resection.

Regulatory Classification

Identification

(1) Cryosurgical unit with a liquid nitrogen cooled cryoprobe and accessories. A cryosurgical unit with a liquid nitrogen cooled cryoprobe and accessories is a device intended to destroy tissue during surgical procedures by applying extreme cold. (2) Cryosurgical unit with a nitrous oxide cooled cryoprobe and accessories. A cryosurgical unit with a nitrous oxide cooled cryoprobe and accessories is a device intended to destroy tissue during surgical procedures, including urological applications, by applying extreme cold. (3) Cryosurgical unit with a carbon dioxide cooled cryoprobe or a carbon dioxide dry ice applicator and accessories. A cryosurgical unit with a carbon dioxide cooled cryoprobe or a carbon dioxide dry ice applicator and accessories is a device intended to destroy tissue during surgical procedures by applying extreme cold. The device is intended to treat disease conditions such as tumors, skin cancers, acne scars, or hemangiomas (benign tumors consisting of newly formed blood vessels) and various benign or malignant gynecological conditions affecting vulvar, vaginal, or cervical tissue. The device is not intended for urological applications.

{0} 510(k) SUMMARY K964336 October 31, 1996 Submitted by: MAR 20 1997 Contact: Cryomedical Sciences, Inc. 1300 Piccard Drive Rockville, Maryland 20850 (301) 417-7070 Fax (310) 417-7077 Richard J. Reinhart, Ph.D. President and CEO or Susan Hayes Administrative Manager Operations Proprietary name: CMS AccuProbe® 610, 620, 630, 640, 650, 660, 670, 680 Common name: Cryosurgical Unit, Cryogenic Surgical Device or Cryoprobe Classification: Cryosurgical unit with Liquid Nitrogen, Class II [21 CFR § 878.4350(a)] The CMS AccuProbe® 600 series consists of two components including: i) a console which holds three dewars of liquid nitrogen (LN₂) (one dewar is filled at a time; one dewar is a receptacle for the circulating LN₂ and the third dewar contains the supercooling chamber); and ii) one to eight (models 610 through 680) cryoprobes with tips extending from the console. The console includes an optional on-board computer which is used as a redundant display system and an archival system to store information from the procedure. The computer does not control or affect the operation of the cryoprobes in any fashion. The cryoprobes consist of interchangeable tips of various materials, sizes and shapes to be utilized as necessary. The device is used to destroy unwanted tissue by application of extreme cold to the selected site. LN₂ is forced through the cryoprobes under pressure. The cryoprobe, having been placed in the appropriate position through the use of ultrasound or another imaging device, then becomes cold and freezes the unwanted tissue. The procedure may be monitored in real-time through the use of imaging modes such as ultrasound. Once the freezing is completed (approximately 20 minutes) the probe will be heated using warm nitrogen gas in order to facilitate thawing and removal of the cryoprobe from the frozen tissue. The cryosurgical procedure is available when surgical resection is not possible and may also provide an alternative to typical resection in certain cases. Page 1 of 2 {1} The CMS AccuProbe® 600 series is similar in form and function to the 550/530 AccuProbe®, being modified models of that device. The CMS AccuProbe® 550/530 was cleared for marketing in November 20, 1995. The intended use and principal of operation are the same.
