Device Story

IVTM system comprises Thermogard HQ console, heat exchange catheter, and sterile tubing kit. Console circulates saline through catheter balloons placed in central venous circulation to heat/cool patient via feedback control. Physician sets target temperature; system monitors patient temperature via YSI 400 series thermistor and adjusts saline temperature in glycol bath. Used in OR/ICU by clinicians. Provides automated thermal regulation to achieve/maintain normothermia or induce/reverse hypothermia. Benefits include precise temperature management for neurocritical/cardiac patients. Subject submission updates console and tubing kit components; catheters remain unchanged from predicate.

Clinical Evidence

No clinical data provided. Substantial equivalence demonstrated via bench testing, electrical safety, electromagnetic compatibility, and software verification.

Technological Characteristics

System: Hypothermia/Thermal Regulating System (21 CFR 870.5900). Console: 115-230V, glycol/water bath, 0-42°C range. Catheters: Polyurethane/PET, heparin-coated, 9.3 Fr, EO sterilized. Connectivity: USB, Wi-Fi, EMR output. Software: IEC 62304 compliant. Standards: ISO 14971, IEC 60601-1, ISO 10993.

Indications for Use

Indicated for adult patients requiring central venous access for cardiac surgery (normothermia) or neurosurgery (mild hypothermia), and for fever reduction in intubated/sedated adult patients with cerebral hemorrhage. Contraindicated for fever reduction in patients with subarachnoid hemorrhage or primary traumatic brain injury due to increased mortality risk.

Regulatory Classification

Identification

Dear Elizabeth Haines:

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 OHTS: 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 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:

{1}------------------------------------------------

# 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).

*Fischer's exact test

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 Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.

{2}------------------------------------------------

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.

| Principle of Operation | It automatically adjusts the temperature of a<br>heater/chiller glycol bath to achieve the<br>patient target temperature that has previously | Same | | |

| | been set by the attending physician. A<br>temperature probe is used to monitor the<br>patient temperature, a catheter is used to<br>exchange heat to and from the patient, and<br>the delta between the target temperature and<br>patient temperature defines the temperature<br>of the saline pumped through the catheter. A<br>heat exchanger placed within the glycol bath<br>heats and cools the saline in the catheter. | | | |
