The subject device and the predicate device have the same intended use: to express and collect milk from a lactating woman's breast. The subject and predicate device have similar technological features, including identical pump and pump settings (vacuum settings, cycle speed, battery life, and use-life). The subject device differs from the predicate device in suction strength and the use of a single use ethylene oxide sterilized kit. The different technological characteristics of the subject device do not raise different questions of safety and effectiveness, as these differences can be assessed by the performance testing outlined below. # SUMMARY OF NON-CLINICAL PERFORMANCE TESTING Pump hardware and software testing were leveraged from K201152. There are no differences in the pump hardware and software between the MilkMate Breast Pump and predicate device. The following data were provided in support of the substantial equivalence determination: - Biocompatibility testing of the sterile kits was performed for endpoints . recommended in the FDA guidance "Use of International Standard ISO- 10993. Biological Evaluation of Medical Devices Part 1: Evaluation and Testing". - Cytotoxicity per ISO 10993-5:2009, Biological evaluation of medical O devices -- Part 5: Tests for in vitro cytotoxicity - Sensitization per ISO 10993-10:2021 Biological evaluation of medical o devices - Part 10: Tests for skin sensitization - o Irritation per ISO 10993-23:2021 Biological evaluation of medical devices - Part 23: Tests for irritation - The ethylene oxide sterilization process used for the MilkMate kit was developed . and validated for a sterility assurance level of 106 per ISO11135: 2014, ISO 11737-1: 2006 and ISO11737-2: 2019. - Testing per ISO 10993-7: 2008 was performed on the MilkMate kits to ● demonstrate acceptable levels of EO residue and Ethylene Chlorohydrin (ECH) residue. {10}------------------------------------------------ - Accelerated aging tests per ASTM-F1980:2021 were performed to support a 1-. year shelf life. At the end of the accelerated aging time, package integrity was evaluated. - After accelerated aging, packaged kits were preconditioned in atmospheric . conditions and subjected to simulated handling and transportation. After preconditioning and simulated transportation and handling, the kits were tested to demonstrate acceptability of the packaging to maintain the sterility of the MilkMate Kits over the shelf-life. - Vacuum and cycle testing were completed to demonstrate the performance of the . MilkMate breast pump and kits. Testing covered: - The full range of kit sizes, o - Both fresh kits and kits that were at the end of the shelf-life, o - Both single and double pumping, O - Low, middle, and high vacuum pressures, o - o Low, middle, and high cycle settings, - Battery and AC power, and o - Stimulation and expression modes o - Leak testing was completed using methods described in ASTM F2096-11 to ● demonstrate that the pouch maintains its integrity throughout the shelf-life. - To support use by multiple users, backflow testing was performed to demonstrate that the breast pump anti-backflow design works as intended with the disposable kits when the milk collection bottle is full in both stimulation and expression modes. # CONCLUSION: The results of the performance testing described above demonstrate that the MilkMate Breast Pump is as safe and effective as the predicate device and supports a determination of substantial equivalence.
