Intended Use
The Infant Heel Warmer™ Heel Snuggler® are instant warm packs intended to be used on an infant's heel to increase blood circulation to the area to aid in the drawing of blood for analysis. It is a single use, nontoxic, non-sterile, disposable device. The Infant Heel Warmer™, Heel Snuggle® have two configurations, the Heel Snuggler®, which is designed to conform to the shape of the infant's heel, and the standard Infant Heel Warmer™. The devices are primarily used in hospitals, Doctor's offices, and other healthcare settings.
Device Story
Single-use, disposable, non-sterile instant warm pack; contains supersaturated sodium acetate solution and catalyst disk. User flexes internal disk to initiate exothermic crystallization; generates heat (104-107°F). Used in hospitals/clinics by healthcare providers to warm infant heels prior to blood draws. Device secured to infant foot/ankle via adhesive straps; straps perforated for easy removal. Heat increases local blood circulation; aids blood collection. Benefits include improved blood flow for easier sampling.
Clinical Evidence
Bench testing only. Evaluated temperature profiles (activation, surface, duration, skin temperature), shelf-life stability (24 months), and burst strength (200 lb compression). Biocompatibility evaluation leveraged from K936084 per ISO-10993 standards.
Technological Characteristics
Single-use, non-sterile, disposable pouch. Materials: Poly/nylon pouch, food-grade sodium acetate and water solution. Activation: Mechanical (flexing metal catalyst disk). Exothermic crystallization principle. Dimensions: 5.5" x 3.5". Adhesive strap attachment. No software or electronic components.
Indications for Use
Indicated for use on infants to increase blood circulation to the heel to facilitate blood collection for analysis.

Dear Amy Pieper:
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.

### Reference Device:
Omni Therm Inc.- Omni Warm Gel Packs - K936084
### Device Description:
The Infant Heel Warmer™/Heel Snuggler® is a single use, disposable pouch that is filled with a super saturated solution of food grade sodium acetate and a catalyst disk. When the catalyst disk inside the packet is flexed by the user, the catalyst disk reacts with the non-toxic solution and initiates a chemical exothermic crystallization of the sodium acetate, generating heat. When activated at 75°F, both models will reach between 104-107°F and then gradually decrease in temperature over time.
The Heel Snuggler® is a butterfly shape with two straps and the Infant Heel Warmer™ is rectangular with one strap. Straps with adhesive ends are attached to the packet for securing the heel warmer to the infant's foot, if desired. Immediately following activation of the user

rests the bottom of the infant's foot on one portion of the packet and holds the other portion of the packet to the ankle. The straps with adhesive tape on the end are then fitted across the infant's foot and ankle and secured to the opposite side of the adhesive portion of the strap is affixed to the packet only, not the infant's skin. The straps on the heel warmer are perforated, which enables the user to easily tear the straps and remove the heel warmer from the infant's foot after use.
