Intended Use

The TRIP Tonometry Catheter, 18F is used for the determination of regional PCO2 (PrCO2) and intramucosal pH (pHi) of the gastric mucosal tissue when used as a gastrointestinal tract access device for connecting the Tonocap™ monitor. The sampling line and biofilter built into the device serve as a means of connecting the catheter to the TONOCAP™ monitor and as transducer protector to prevent patient cross-contamination and monitor damage, respectively. Since it incorporates a vented gastric sump it is also used for feeding and/or decompression or aspiration of the contents of the stomach.

Device Story

TRIP Tonometry Catheter 18F functions as gastrointestinal access device; connects to Tonocap monitor for determination of regional gastric mucosal PCO2 (PrCO2) and intramucosal pH (pHi). Device features integrated sampling line and biofilter to protect monitor and prevent cross-contamination; includes vented gastric sump for feeding, decompression, or gastric aspiration. Used in clinical settings (OR, ICU, ER) by healthcare professionals to monitor patients with suspected mesenteric ischemia. Output provides physiological data to clinicians for assessment of tissue perfusion and ischemia status, aiding clinical decision-making regarding patient management.

Clinical Evidence

No clinical data provided; substantial equivalence based on device design and intended use.

Technological Characteristics

18F catheter; includes sampling line, biofilter, and vented gastric sump. Functions as gastrointestinal access device for PCO2/pH monitoring and gastric decompression/feeding. Connects to external Tonocap monitor.

Indications for Use

Indicated for surgical/operating room, intensive care unit, emergency/trauma, and hospital patients with suspected mesenteric ischemia.

Regulatory Classification

Identification

A carbon dioxide gas analyzer is a device intended to measure the concentration of carbon dioxide in a gas mixture to aid in determining the patient's ventilatory, circulatory, and metabolic status. The device may use techniques such as chemical titration, absorption of infrared radiation, gas chromatography, or mass spectrometry.

Dear Mr. Kent:

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 exactment 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 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 device as described in your 510(k) premarket notification. The FDA finding of substantial equivalence of your device to a legally marketed predicate device results in a classification 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 diagnostic 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]. Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21 CFR 807.97).
