No
The document describes a temperature regulation system using feedback control, which is a standard engineering principle and does not inherently involve AI or ML. There are no mentions of AI, ML, or related concepts in the provided text.
Yes
The device is indicated for use in treating various medical conditions by regulating body temperature (e.g., maintaining normothermia, inducing/maintaining/reversing hypothermia, reducing fever), which are therapeutic interventions.
No
The device is described as a "patient temperature regulation apparatus employing feedback control" and its indications for use relate to achieving/maintaining normothermia, inducing/maintaining/reversing hypothermia, and fever reduction. These are therapeutic actions, not diagnostic ones.
No
The device description explicitly states the system is comprised of an external heat exchange console and intravascular heat exchange catheters, which are hardware components. The submission is for software changes to these consoles, but the overall device is a hardware system with software control.
Based on the provided information, this device is not an In Vitro Diagnostic (IVD).
Here's why:
- Intended Use: The intended use clearly describes the device as being used to regulate a patient's body temperature (achieve/maintain normothermia, induce/maintain/reverse hypothermia, fever reduction) by directly interacting with the central venous circulation. This is a therapeutic intervention performed in vivo (within the living body).
- Device Description: The description details an external console and intravascular catheters that exchange heat directly with the blood. This is a physical process happening within the patient's circulatory system.
- Lack of IVD Characteristics: An IVD device is typically used to examine specimens derived from the human body (like blood, urine, tissue) in vitro (outside the living body) to provide information for diagnosis, monitoring, or screening. This device does not perform any such analysis of bodily specimens.
The device is a therapeutic device used for temperature management within the patient's body.

Dear Brian Robey:
We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate 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) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act and the limitations described below. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database located at
https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. 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. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.
The OHT5: Office of Neurological and Physical Medicine Devices has determined that there is a reasonable likelihood that the Solex 7 Intravascular Heat Exchange Catheter will be used for an intended use not identified in the proposed labeling and that such use could cause harm. Therefore, in accordance with
1
Section 513(i)(1)(E) of the Act, the following limitation must appear in the box warning immediately following the indications for use statement of the device's labeling:
Warning – Fever Reduction
The safety of this device has not been demonstrated for fever reduction in patients presenting with subarachnoid hemorrhage or primary traumatic brain injury. A randomized controlled trial of endovascular cooling in patients with fever associated with subarachnoid hemorrhage and primary traumatic brain injury has shown increased mortality as compared to patients receiving standard of care.
The OHT5: Office of Neurological and Physical Medicine Devices has determined that there is a reasonable likelihood that the Cool Line Intravascular Heat Exchange Catheter will be used for an intended use not identified in the proposed labeling and that such use could cause harm. Therefore, in accordance with Section 513(i)(1)(E) of the Act, the following limitation must appear in the box warning immediately following the indications for use statement of the device's labeling:
Warning - Fever Reduction
The safety of this device has not been demonstrated for fever reduction in patients presenting with subarachnoid hemorrhage or primary traumatic brain injury. The safety and effectiveness of this device was examined in a randomized controlled trial of 296 patients. The mortality results reported in this trial, for the four patient cohorts enrolled, are presented in the table below (CI - cerebral infarction, ICH - intracerebral hemorrhage, PTBI - primary traumatic brain injury, SAH subarachnoid hemorrhage).

For more details on the clinical trial results, refer to the Physician's Manual - "Normothermia for the Neurocritically Ill stroke patient."
Please note that the above labeling limitations are required by Section 513(i)(1)(E) of the Act. Therefore, a new 510(k) is required before these limitations are modified in any way or removed from the device's labeling.
The FDA finding of substantial equivalence of your device to a legally marketed predicate device results in a classification for your device and permits your device to proceed to the market. This letter will allow you to begin marketing your device as described in your Section 510(k) premarket notification if the limitation statement described above is added to your labeling.
If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of
2
Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.
Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); medical device reporting of medical device-related adverse events) (21 CFR 803) for devices or postmarketing safety reporting (21 CFR 4, Subpart B) for combination products (see https://www.fda.gov/combination-products/guidance-regulatory-information/postmarketing-safety-reportingcombination-products); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820) for devices or current good manufacturing practices (21 CFR 4, Subpart A) for combination products; and, if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.
Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21 CFR Part 807.97). For questions regarding the reporting of adverse events under the MDR regulation (21 CFR Part 803), please go to https://www.fda.gov/medical-device-safety/medical-device-reportingmdr-how-report-medical-device-problems.
