Intended Use

For thermal regulation of a patient's temperature to prevent hypothermia and/or reduce cold discomfort during and after surgical procedures. It is intended for use by appropriately trained healthcare professionals in clinical environments.

Device Story

Convective warming blankets (SW-2013, SW-2014L, SW-2014R, SW-2015, SW-2016, SW-2018, SW-2019) function as components of the Snuggle Warm Convective Warming System (SW-4000/EQ-5000). System consists of a warming unit, hose, and single-use blanket. Warming unit generates warm air, delivered through hose to blanket; air distributes through internal channels and exits via perforations onto patient. Used in clinical environments by healthcare professionals to maintain patient normothermia during/after surgery. Prevents hypothermia and reduces cold discomfort. Certain models (SW-2016, SW-2018, SW-2019) feature movable panels for surgical access.

Clinical Evidence

No clinical data. Substantial equivalence established via bench testing and comparison of technological characteristics to predicate devices.

Technological Characteristics

Single-use convective warming blankets. Materials and manufacturing processes similar to predicates. Air distribution via internal channels and perforations. Features include movable panels for surgical access. Complies with ASTM F2196:2002 (forced air patient temperature management) and ISO 10993-1:2003 (biocompatibility).

Indications for Use

Indicated for patients undergoing surgical procedures requiring thermal regulation to prevent hypothermia or reduce cold discomfort. Intended for use by trained healthcare professionals in clinical settings.

Regulatory Classification

Identification

### Device Description:

.

Snuggle Warm® Convective Warming Systems (SW-4000 and EQ-5000) that will include the proposed blankets (Model SW-2013, SW-2014R, SW-2015, SW-2016, SW-2018, SW-2018 & SW-2019)

- The Convective Warming Systems (SW-4000 and EQ-5000), are identified as a Thermal . Regulation System by the FDA, consists of a Convective Warming Unit (temperature controller), a hose, and a single-use Convective Warming Blanket.
- The Convective Warming Systems' (SW-4000 and EQ-5000) single-use disposable . Convective Warming Blankets are placed in contact with the patient and attached to a warming unit via a hose with hose-end temperature controls. The warming unit generates warm air that is distributed throughout the warming blanket to warm the patient during and after surgical procedures.
- It is intended for thermally regulating a patient's temperature to prevent hypothermia by a . warm air heated blanket system to reduce cold discomfort during and after surgical procedures.

The seven proposed blankets are single-use Convective Warming Blankets that will be added to the existing Convective Warming Blanket family. They are components of the Convective Warming Systems (SW-4000 and EQ-5000) of which the indications for use remain the same.

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

#### Indications for Use:

ﺬ

For thermal regulation of a patient's temperature to prevent hypothermia and/or reduce cold discomfort during and after surgical procedures. It is intended for use by appropriately trained healthcare professionals in clinical environments.

#### Technological Characteristics:

The proposed and predicate Snuggle Warm® convective warming blankets are made of similar materials and employ similar manufacturing processes. The warm air is distributed around the patient's body through the delivery channels and exits the blanket through a specially designed series of perforations in the patient side of the blanket.

The proposed SW-2016 Full Body Split Access blanket, the SW-2018 Multi Access blanket and the SW-2019 Poncho blanket have movable panels which can be secured away from the surgical area similiar to the Bair Hugger® model 610 Full Body Surgical Blanket.

#### Non-Clinical Data:

Bench testing was performed to demonstrate that the proposed convective warming blankets are substantially equivalent to the existing Snuggle Warm " convective warming blankets currently marketed by Smiths Medical. The blankets are designed to meet the requirements of the following standards:

- . ASTM F2196:2002, Standard Specification for Circulating Liquid and Forced Air Patient Temperature Management
- . ISO 10993-1 2003, Biological Evaluation of Medical Devices - Evaluation and Testing

### Clinical Data:

Not required

#### Conclusion:

The proposed Convective Warming Blankets are safe and effective as well being substantially equivalent to the predicate devices.

Very truly yours,

SMITHS MEDICAL ASD, INC.

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. 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.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to such 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 801); good manufacturing practice requirements as set forth in the quality systems (OS) regulation (21 CFR Part 820); and if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050. This letter will allow you to begin marketing your device as described in your Section 510(k) premarket notification. The FDA finding of substantial equivalence of your device to a legally marketed predicate device results in a classification for your device and thus, permits your device to proceed to the market.

If you desire specific advice for your device on our labeling regulation (21 CFR Part 801), please contact the Center for Devices and Radiological Health's (CDRH's) Office of Compliance at [phone]. Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21CFR Part 807.97).
