Intended Use
The CMS Cryo-lite® System has the same indications for use as its predicate devices, the Frigitronics Model 5900, Frigitronics Cryocare I and the Cryomedics Model MT700 . The Cryo-lite® System is intended to be used as a cryosurgical tool for destruction of unwanted tissue in the fields of dermatology, gynecology general surgery, etc. and veterinary medicine.
Device Description
The CMS Cryo-lite® System is a completely disposable hand-held cryosurgical device. Both Crvo-lite® System Models 2001 and 2002 consist of hand-helo body, a physician-selected cryogen packet and single cryoprope of varying materials, sizes and shapes. Cryogens available with this system are liquid nitrogen, nitrous oxide, carbon dioxide and argon. The Crvo-lite® System is used to destroy unwanted tissue by application of extreme cold to the selected site. The cryogen is forced through the cryoprobes under pressure. The cryoprobe, having been placed in the appropriate position through the use of ultrasound, another imaging device or visual observation then becomes cold and freezes the unwanted tissue. Cryosurgical procedures are used when surgical resection is not indicated, and may also provide an alternative to typical resection in certain cases.
More Information

Not Found

No
The device description and intended use focus on a purely mechanical cryosurgical process using cryogens and probes, with no mention of AI/ML capabilities or data processing for decision-making or analysis.

Yes
The device is described as a "cryosurgical tool for destruction of unwanted tissue," which is a therapeutic intervention aimed at treating medical conditions.

No

The device is a cryosurgical tool intended for the destruction of unwanted tissue, which is a therapeutic rather than a diagnostic function.

No

The device description clearly states it is a "completely disposable hand-held cryosurgical device" consisting of a hand-held body, cryogen packet, and cryoprobe, indicating it is a hardware device.

Based on the provided information, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • IVD Definition: In vitro diagnostics are tests performed on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections.
  • Device Function: The CMS Cryo-lite® System is a cryosurgical tool used to destroy unwanted tissue by applying extreme cold directly to the tissue. This is a surgical procedure performed in vivo (on the living body), not a diagnostic test performed in vitro (outside the body).
  • Intended Use: The intended use clearly states it's a "cryosurgical tool for destruction of unwanted tissue."
  • Mechanism of Action: The device works by freezing tissue directly, not by analyzing a sample taken from the body.

Therefore, the CMS Cryo-lite® System falls under the category of a surgical device, not an in vitro diagnostic device.

Proprietary name: CMS Cryolite

Cryosurgical Unit, Cryogenic Surgical Device or Cryoprobe Common name:

Cryosurgical unit with Liquid Nitrogen, Nitrous Oxide, Carbon Classification: Dioxide, Class II [21 CFR § 878.4350(a).

The CMS Cryo-lite® System is a completely disposable hand-held cryosurgical device. Both Crvo-lite® System Models 2001 and 2002 consist of hand-helo body, a physician-selected cryogen packet and single cryoprope of varying materials, sizes and shapes. Cryogens available with this system are liquid nitrogen, nitrous oxide, carbon dioxide and argon.

The Crvo-lite® System is used to destroy unwanted tissue by application of extreme cold to the selected site. The cryogen is forced through the cryoprobes under pressure. The cryoprobe, having been placed in the appropriate position through the use of ultrasound, another imaging device or visual observation then becomes cold and freezes the unwanted tissue. Cryosurgical procedures are used when surgical resection is not indicated, and may also provide an alternative to typical resection in certain cases.

The CMS Cryo-lite® System is similar in form and function to the Frigitronics' Cryocare I System and its Cryo Surg Model 5900 (K840536) and Cabot Medical's Cryomedics MT700. Intended use for the CMS Cryo-lite® System is the same as those listed for the CMS Cryolite® System predicate devices.

Dear Dr. Reinhart:

We have reviewed your Section 510(k) notification of intent to market the device referenced above and we have determined the device is 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 device, 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 device is classified (see above) into either class II (Special Controls) or class III (Premarket Approval), it may be subject to such additional controls. Existing major regulations affecting your device 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. Failure to comply with the GMP regulation may result in regulatory action. In addition, FDA may publish further announcements concerning your device in the Federal Register. Please note: this response to your premarket notification submission 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.
