Indications for Use

The Care Wise C-Trak® Automatic Analyzer is designed- as are all similar devices - to detect and quantify nuclear radiation. It is indicated for external and intraoperative detection of radioactivity in body tissues or organs, such as bowel, bone, lymphatics, and red blood cells, where radiopharmaceuticals are administered.

Device Story

C-Trak® Automatic Analyzer is a battery-powered, portable radioisotope detector. Device utilizes a handheld probe to detect nuclear radiation in body tissues or organs; processes signals to quantify radioactivity levels; displays data and system parameters to the user. Used in operating room environments by clinicians for intraoperative or external detection. System operates exclusively on internal batteries to ensure electrical safety; no AC power connection. Output assists clinicians in identifying radioactive tissues/organs following radiopharmaceutical administration, facilitating surgical or diagnostic decision-making.

Clinical Evidence

No clinical data provided. Substantial equivalence is based on technological similarity to predicate devices and established use in nuclear medicine.

Technological Characteristics

Portable, battery-powered radioisotope detector. Handheld probe interface. System includes analyzer unit for signal processing and display. No AC power connectivity. Designed for operating room use. No software algorithm details provided.

Indications for Use

Indicated for external and intraoperative detection of radioactivity in body tissues or organs (e.g., bowel, bone, lymphatics, red blood cells) in patients administered radiopharmaceuticals.

Regulatory Classification

Identification

A nuclear uptake probe is a device intended to measure the amount of radionuclide taken up by a particular organ or body region. This generic type of device may include a single or multiple detector probe, signal analysis and display equipment, patient and equipment supports, component parts, and accessories.

## Predicate Devices

NeoProbe 1000 and 1500 Analyzers and accessories currently marketed by the NeoProbe Corporation of Dublin, Ohio (K971167)

Care Wise C-Trak® Biopsy System (K922117)

Care Wise OncoProbe II™ Analyzer (K896588)

## Intended Use

The intended use of the device here in question, i.e. the Care Wise C-Trak® Automatic Analyzer, remains unchanged from the intended use of prior predicate Care Wise and other portable radioisotope detectors. The Care Wise C-Trake Automatic Analyzer is designed- as are all similar devices - to detect and quantify nuclear radiation. It is indicated for external and intraoperative detection of radioactivity in body tissues or organs, such as bowel, bone, lymphatics, and red blood cells, where radiopharmaceuticals are administered.

## Device Description

The Care Wise C-Trak® Automatic Analyzer consists of a battery-powered analyzer designed to operate a hand held probe, display the data from the detected radiation, and display and control the system's operating parameters.

# Safety and Effectiveness

Comprehensive shielding of high voltage sites within the instrument and operation only from internal batteries eliminate the possibility of significant electrical current leakage to patient or user under normal operating conditions. The C-Trak system's electrical safety is greatly enhanced by the fact that the system is not designed or manufactured to be connected to an AC power line or any other type of external power supply. The system has been designed and manufactured for safe operation in an operating room environment, as long as flammable anesthetic gasses are not used.

Care Wise Medical Products Corporation believes that the C-Trak® Automatic Analyzer is substantially equivalent not only to each of its other analyzer products but also to products marketed before the passage of the Medical Amendments of May 28, 1976 and to other products such as the NeoProbe 1000 and 1500 Analyzers currently marketed by the NeoProbe Corporation of Dublin, Ohio. Documentation for this opinion is found on page 65A of Volume 17 of the Journal of Nuclear Medicine, January 1976, enclosed as Attachment V of this application and in NeoProbe promotional literature enclosed in Attachment VI. We intend to market both this and previously cleared technologies.

Dear Mr. Wise:

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 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 (OS) 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 device in the Federal Register. Please note: this response to your premarket notification submission does not affect any obligation you might have under sections 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 device as described in your 510Ks premarket notification. The FDA finding of substantial equivalence of your device to a legally marketed predication for your device and thus, permits your device to proceed to the market.

If you desire specific advice for your device on our labeling regulation (21 CFR Part 801 and additionally 809.10 for in vitro disgnostic devices), please contact the Office of Compliance at [phone]. Additionally, for questions on the promotion and advertising of your device, please contact the Office of Compliance at [phone].
