No
The description focuses on a warming gown and its use with a warming unit, with no mention of AI or ML capabilities.
Yes
The device is used to prevent and treat hypothermia perioperatively, which classifies it as a therapeutic intervention.
No
This device is a warming gown intended to prevent and treat hypothermia, not to diagnose a medical condition.
No
The device description clearly outlines a physical warming gown with insulation and components like a lower body insert and warming blanket. It is part of a system that includes a warming unit (hardware). There is no mention of software as the primary or sole component of the device.
Based on the provided text, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is "perioperatively to prevent and treat hypothermia." This describes a therapeutic intervention applied directly to the patient's body to manage their temperature.
- Device Description: The device is a warming gown used with a warming unit. This is a physical device that provides external heat to the patient.
- Lack of Diagnostic Purpose: There is no mention of the device being used to examine specimens from the human body to provide information for diagnosis, monitoring, or screening. IVDs are used to analyze biological samples (blood, urine, tissue, etc.) to gain insights into a patient's health status.
The device is clearly designed for patient temperature management, which is a therapeutic function, not a diagnostic one.

Device Description
The 3M™ Bair Hugger™ Universal Warming Gown made with Thinsulate™ Insulation is a disposable, single-patient perioperative warming gown with 3M™ Thinsulate™ Insulation. The warming gown is intended to be worn throughout the entire journey: before, during and after surgery.
Bair Hugger™ warming gowns are part of the Bair Hugger™ warming system; there are two parts to the system: the warming gown and warming unit (temperature management unit). The Universal Warming Gown is available in three sizes (small, standard, and x-large) and is intended to be used with the Bair Hugger™ 700 series or 675 warming unit. The system, monitored and controlled by a trained clinician, is used perioperatively to prevent and treat hypothermia.
The warming gown has two patient warming options: an integrated lower body insert and a removable multi-position warming blanket. The lower body insert has a lower midline hose port, and the warming blanket is to be removed from a pocket in the front upper section of the gown. The warming blanket can be used alone or in combination with the warming gown during surgery.
After surgery, the warming gown should be re-domed and used to warm the patient using the lower midline hose port.

Dear Hilary Hovde:
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. 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.
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.
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
1
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).
