It functions via mechanical action (hydrodynamic shear) as the fluid moves across the wound surface, aided by a surfactant (sodium lauryl sulfate) that assists in solubilizing debris. The solution is supplied in a 500mL polypropylene container with a spikeable port. It is intended for use by healthcare providers in clinical settings, applied via manual syringe or powered irrigation devices. The solution helps maintain a clean wound environment, facilitating the natural healing process. It does not inhibit normal wound healing. ## Clinical Evidence Evidence includes biocompatibility testing (ISO 10993-1), performance bench testing, a porcine wound healing study, and a human clinical study. Bench testing confirmed adequate irrigation pressures and equivalent debris removal efficacy compared to the predicate. The porcine study (n=16 pigs) demonstrated no inhibition of normal wound healing over 25 days. A human repeat patch test (clinical) determined the solution is a non-irritant with no adverse events. ## Technological Characteristics Composition: Water, citric acid (32.50 g/L), sodium citrate (31.33 g/L), sodium lauryl sulfate (1.00 g/L). Form factor: 500mL polypropylene container with spikeable port. Mechanism: Mechanical irrigation via hydrodynamic shear. Sterility: Sterile. No software or electronic components. ## Predicate Devices - Next Science® Irrigation Solution ([K161165](/device/K161165.md)) ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).

The battery of studies includes the following: - Material Mediated Pyrogenicity using USP <151> ● - . Guinea Pig Maximization Sensitization Test - Porcine Wound Healing to address the cytotoxicity endpoint ● - . Toxicological Risk Assessment per ISO 10993-17 - Chemical Characterization of Extractables and Leachables for device packaging ● - . Irritation (Human) ### Performance Bench Testing The following bench tests were conducted to support the substantial equivalency of MIS Solution in removing debris from a surface and adequate irrigation: - Compatibility and Irrigation Force Comparison the test verified that use of the subject ● device in manual and powered irrigation devices were able to reach published pressures deemed adequate for wound irrigation. - Combined Dissolution Efficacy The test demonstrated that MIS Solution and the . predicate device are substantially equivalent at removing debris under static conditions. ### Animal Testing A Porcine Wound Healing Study was conducted to evaluate the effect of the subject device components on the wound healing process. In the animal study conducted, 16 domestic pigs were used, each receiving eight wounds, four on the left and right sides of the animal's back parallel to the spine line. Two or three of the animal's wounds were assigned to a treatment group of the subject device, the predicate device or a negative control. Under the conditions of the study, MIS Solution did not inhibit normal wound healing over 25 days in this porcine wound healing study. ### Clinical Study MIS Solution was evaluated in a Human Repeat Patch Test to evaluate the irritation endpoint in humans. MIS Solution was determined to be a non-irritant. There were no adverse events or complications in this study. {6}------------------------------------------------ #### Conclusion: The conclusions drawn from biocompatibility, performance tests and a clinical study demonstrate that MIS Solution is as safe and effective as the legally marketed device, Next Science® Irrigation Solution (K161165). --- **Source:** [https://fda.innolitics.com/device/K203835](https://fda.innolitics.com/device/K203835) **Published by [Innolitics](https://innolitics.com)** — a medical-device software consultancy.
