No
The device description focuses on a mechanical and enzymatic process for hydrolyzing fats, with no mention of AI or ML technologies. The performance studies also do not indicate the use of AI/ML.
Yes
The device is intended to mimic the function of the enzyme lipase in patients who do not excrete sufficient levels of pancreatic lipase, helping to break down fats for absorption and utilization by the body. This therapeutic action aims to improve a physiological function.
No.
The device is described as an "accessory designed to fit in line with currently used enteral feeding circuits" that "hydrolyzes fats in enteral formula" to aid in absorption and utilization by the body, mimicking the function of an enzyme. It does not diagnose any condition or disease.
No
The device description clearly outlines a physical cartridge containing beads with immobilized enzymes, filters, and inlet/outlet ports. This is a hardware device designed to be integrated into an enteral feeding circuit.
Based on the provided information, the RELiZORB device is not an In Vitro Diagnostic (IVD).
Here's why:
- Intended Use: The intended use is to "hydrolyze fats in enteral formula." This is a therapeutic action performed on the formula itself, not a diagnostic test performed on a biological sample from a patient to provide information about their health status.
- Device Description: The device description clearly explains that it's an accessory for enteral feeding circuits that breaks down fats in the formula using an immobilized enzyme. This is a treatment or processing function, not a diagnostic one.
- Lack of Diagnostic Elements: There is no mention of analyzing biological samples (blood, urine, tissue, etc.), detecting biomarkers, or providing information for diagnosis, monitoring, or screening of a disease or condition.
- Performance Studies: The performance studies described focus on the device's ability to hydrolyze fats, its mechanical properties, flow rate, and shelf life. These are performance characteristics relevant to its function as a treatment accessory, not diagnostic accuracy metrics.
In summary, the RELiZORB device is designed to modify enteral formula before it enters the patient's body, facilitating nutrient absorption. This is a therapeutic or supportive function, not a diagnostic one.

Device Description
The RELiZORB device is a point-of-care accessory designed to fit in line with currently used enteral feeding circuits. RELiZORB is designed to hydrolyze (break down) fats present in enteral formulas from triglycerides into fatty acids and monoglycerides to allow for their absorption and utilization by the body. This breakdown of fats by the RELiZORB is intended to mimic the function of the enzyme lipase in patients who do not excrete sufficient levels of pancreatic lipase. RELiZORB is comprised of a cylindrical, hollow cartridge with a single inlet port and a single outlet port connection. Inside the cartridge, there are small white beads. The digestive enzyme, lipase, is covalently bound to the small white beads. The lipase-bead complex, iLipaseTM (immobilized lipase), is retained within the cartridge during use by filters on both ends of the cartridge. The fat in enteral formulas is hydrolyzed as it comes in contact with iLipase as the formula passes through the cartridge.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Shelf life testing of RELIZORB was completed and met the acceptance criteria in the protocol. The shelf life test results support the proposed edit to the labeling with respect to product stability. The RELIZORB device was previously tested to demonstrate that the device performs as intended under anticipated conditions of use, and safety, including: Tensile and mechanical strength Flow rate Demonstration of enzymatic effect on macronutrients Impurities/degradants characterization Animal testing to demonstrate hydrolysis effect Human factors testing RELiZORB testing was done per design control requirements of 21 CFR Part 820. The Risk management file was reviewed and there was no significant change to the risk assessment as a result of the proposed minor change to the labeling. Alcresta develops and manufactures RELIZORB in compliance with the Quality System regulations (21 CFR 820).

(a)
Identification. An enzyme packed cartridge is anex vivo prescription device that is used in enzymatic hydrolysis of macronutrients into their essential nutrient forms at the time of delivery. The device consists of an outer casing containing an inert polymer with a covalently bound enzyme through which nutritional formula is directed. The device fits in line with enteral feeding systems.(b)
Classification. Class II (special controls). The special controls for this device are:(1) The patient contacting components of the device must be demonstrated to be biocompatible.

(ii) Flow rate and leakage testing to demonstrate that the device does not impede the flow of enteral formula;
(iii) Demonstration of enzymatic effect on intended macronutrient;
(iv) The amount of enzyme that exits the cartridge must be characterized;
