The summary describes a mechanical heating and cooling system with no mention of AI or ML capabilities. The performance studies focus on physical and microbiological testing.
Yes.
The device is used to warm or cool a patient during cardiopulmonary bypass procedures, which directly affects the patient's physiological state for therapeutic purposes.
No
Explanation: The device description and intended use clearly state that the 3T system is used to circulate water to warm or cool a patient during medical procedures. There is no mention of diagnostic functions, such as detecting, identifying, or monitoring a patient's condition.
No
The device description clearly outlines a physical heating/cooling base unit with multiple water circuits, optional hardware components (blankets, tubing, cables), and a disposable aerosol collection set. The performance studies also focus on hardware-related aspects like emission reduction, heating/cooling performance, corrosion, and cleaning/disinfection of physical components. This is not a software-only device.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use clearly states that the device is used to "circulate water through heat exchangers to warm or cool a patient during cardiopulmonary bypass procedures." This is a direct therapeutic or supportive function applied to the patient's body, not a diagnostic test performed on a sample taken from the body.
- Device Description: The description details a system for circulating water for temperature control, including components like blankets and tubing. This aligns with a device used for patient temperature management during surgery.
- Lack of IVD Characteristics: There is no mention of the device being used to analyze samples (blood, urine, tissue, etc.), detect markers, or provide diagnostic information about a patient's condition. The performance studies focus on the device's ability to reduce emissions, maintain temperature, and be cleaned and disinfected, all of which are relevant to a medical device used in a clinical setting but not specifically for in vitro diagnosis.
Therefore, the Heater-Cooler System 3T is a medical device used for patient temperature management during surgery, not an In Vitro Diagnostic device.

Intended Use / Indications for Use
The Heater-Cooler 3T System (3T System) is used to circulate water through heat exchangers to warm or cool a patient during cardiopulmonary bypass procedures lasting 6 hours or less.
Device Description
The 3T System is an independent (i.e., independent of the water supply) 3-circuit heating/cooling base unit that includes three water circuits (two circuits for the patient supplied by one tank (for the heating/cooling blanket, the oxygenator) and one interchangeable heating/cooling circuit for cardioplegia.

The 3T System includes a disposable aerosol collection set that consists of a canister connected to the 3T System and the user facility's vacuum source that captures emissions that are drawn from the tank using negative pressure created by the user facility's vacuum.
- Various cables.
Technological Characteristics
The technological characteristics of the Final Configuration 3T System are similar to the cleared 3T System (K052601), with a number of minor modifications to the hardware, software and labeling of the device. Both devices employ an independent (i.e., independent of the water supply) heating/cooling base unit that includes three water circuits (two circuits for the patient supplied by one tank (for the heating/cooling blanket, the oxygenator) and one interchangeable heating/cooling circuit for cardioplegia. Both devices can also be used with the same types of optional components and accessories, including heating-cooling blankets and various cables and tubing.

Substantial Equivalence
The Final Configuration 3T System has very similar indications for use as the cleared 3T System. In addition, the Final Configuration and cleared 3T Systems have the same fundamental scientific technology, and similar technological characteristics. As explained in the attached 510(k) notice, the minor differences discussed do not raise new or different questions of safety or effectiveness. Furthermore, performance and validation testing demonstrate that the modified 3T System is as safe and effective as the predicate device. Thus, the Company maintains that the Final Configuration 3T System is substantially equivalent to its predicate device.
