Overview

AI-generated summary, 20 Sep 2026

Written by a language model from registry data. Not verified by deviCERTS or the manufacturer. The registry data above is the record.

The Flow-Directed Thermodilution Catheter is a Probe, Thermodilution device, as classified under FDA product code KRB. It is designed for measuring cardiac output by injecting a known volume of cold saline into the venous system and detecting the resulting temperature change in the pulmonary artery. This method relies on thermal dilution principles to provide accurate hemodynamic assessments, commonly used in critical care and cardiovascular monitoring settings.

This device is intended for single-use in clinical environments and requires sterile handling. It is classified as a Class II medical device under FDA regulations (870.1915) and has received FDA 510(k) clearance (K812800). The catheter is supplied as a disposable probe and must be used in conjunction with compatible monitoring systems. No MRI safety information is specified, and storage conditions are not detailed in the regulatory data.

Questions

AI-generated answers, 20 Sep 2026

Written by a language model from registry data. Not verified by deviCERTS or the manufacturer. The registry data above is the record.

  • What clinical setting is the Flow-Directed Thermodilution Catheter primarily used in, and how does it work?

    The Flow-Directed Thermodilution Catheter is designed for critical care and cardiovascular monitoring settings. It measures cardiac output by injecting a known volume of cold saline into the venous system and detecting the resulting temperature change in the pulmonary artery. This thermal dilution method provides accurate hemodynamic assessments, helping clinicians evaluate heart function and circulation efficiency.

  • Is the Flow-Directed Thermodilution Catheter reusable, or is it intended for single-use only?

    The device is explicitly intended for single-use in clinical environments. This design ensures sterility and reduces the risk of contamination or cross-infection between patients, which is critical for invasive medical devices.

  • What types of monitoring systems are compatible with this catheter, and how is it supplied?

    The Flow-Directed Thermodilution Catheter is supplied as a disposable probe and must be used with compatible monitoring systems designed for thermodilution cardiac output measurements. Since it is a standalone probe, it relies on external systems to process the thermal data and calculate cardiac output.

  • Are there any specific storage instructions or conditions mentioned for this device?

    The regulatory data does not specify storage conditions for the Flow-Directed Thermodilution Catheter. However, as a sterile, single-use device, it should be stored in a clean, dry environment away from direct sunlight or extreme temperatures until use.
