The Celsius Control™ System is a thermal regulating system intended to induce, maintain and reverse mild hypothermia in neurosurgical patients in surgery and in recovery/intensive care, to achieve and/or maintain normothermia in cardiac surgery patients in surgery and in recovery/ intensive care, and for use in fever reduction, as an adjunct to other antipyretic therapy, in patients with cerebral infarction and intracerebral hemorrhage who required access to the central venous circulation and who are intubated and sedated.
The subject device is a thermal regulating system consisting of three (3) parts:
- an endovascular catheter having a heat exchange element at the distal end, through which a thermal transfer fluid is circulated to cool or warm the blood, and which is available in various diameters from 9 french to 14 french;
- a console containing refrigeration/heating elements, a heat exchanger to cool and warm the circulating fluid, a pump to circulate that fluid, and controls and software necessary to operate the system; and
- a sterile tubing set to connect the console to the catheter, and through which the thermal transfer fluid is circulated.
Two (2) models of the System are available: One which uses conventional, off-the-shelf thermistor probes such as YSI-400 esophageal probes, to monitor patient temperature and control System operation, and one that uses a thermistor integral to the catheter.
The provided text is a 510(k) Summary for the INNERCOOL therapies, Inc. Celsius Control™ System. It describes the device, its intended use, and comparison to predicate devices, but it does not contain information about specific acceptance criteria, device performance testing results, sample sizes for test or training sets, ground truth establishment, expert qualifications, or MRMC studies. Therefore, I am unable to fill out the requested table and answer the questions based solely on the provided text.
The document focuses on establishing substantial equivalence to predicate devices for regulatory clearance, rather than detailing the specifics of performance studies against defined acceptance criteria.
Information NOT Found in the Document:
- A table of acceptance criteria and the reported device performance: Not present. The document states "The subject device has equivalent performance in inducing and reversing hypothermia, and in maintaining normothermia," but it doesn't provide specific quantitative acceptance criteria or reported performance metrics.
- Sample sized used for the test set and the data provenance: Not present.
- Number of experts used to establish the ground truth for the test set and the qualifications of those experts: Not present.
- Adjudication method (e.g. 2+1, 3+1, none) for the test set: Not present.
- If a multi reader multi case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance: Not present. This device is a thermal regulating system, not an AI-assisted diagnostic tool for human readers.
- If a standalone (i.e. algorithm only without human-in-the loop performance) was done: Not present. This device is a physical therapeutic system, not an algorithm.
- The type of ground truth used (expert concensus, pathology, outcomes data, etc): Not applicable in the context of this device's type of evaluation as described. Performance for a thermal regulating system would typically involve physiological measurements in subjects or bench testing.
- The sample size for the training set: Not present.
- How the ground truth for the training set was established: Not present.

(a)
Identification. A thermal regulating system is an external system consisting of a device that is placed in contact with the patient and a temperature controller for the device. The system is used to regulate patient temperature.(b)
Classification. Class II (performance standards).
