Used in acute, extended, and home care settings by healthcare professionals. Healthcare provider applies dressing to wound; connects to vacuum pump; monitors wound healing progress. Benefits include effective exudate management and wound bed preparation. ## Clinical Evidence Bench testing only. Evaluated foam performance under constant (125mmHg) and variable (0-150mmHg) negative pressure over 72 hours. Metrics included dimensional stability, suction pressure variation (<+/-5mmHg difference vs predicate), and fluid removal rates using synthetic blood/plasma. Biocompatibility testing per ISO 10993 (L929 MEM elution, intracutaneous injection, Kligman maximization) and ASTM F756-08 (hemolysis) confirmed safety. ## Technological Characteristics Reticulated flexible polyether-based polyurethane foam; hydrophobic. Available in three sizes (100x80x30mm, 125x190x30mm, 150x250x30mm). Sterile (EtO). Single-use. No electronic components; passive dressing used with external powered suction pump. ## Regulatory Identification A powered suction pump is a portable, AC-powered or compressed air-powered device intended to be used to remove infectious materials from wounds or fluids from a patient's airway or respiratory support system. The device may be used during surgery in the operating room or at the patient's bedside. The device may include a microbial filter. ## Predicate Devices - Genadyne Biotechnologies, Inc.

The following bench tests were conducted: - 1. Dimensions were recorded before and after the 72 hour bench test. The results demonstrated after undergoing long periods of suction pressures both predicate and Kevo dressings appeared unchanged. - 2. Suction pressures were recorded to determine the variation in suction pressures between the Kevo NPWT- αHemo30 Foam Dressing Kit and the Genadyne A4-XLR8 Foam Dressing Kit. It was determined that the difference in suction pressures between the two dressings is <+/-5mmHg. It was also noted that the pressure distribution appeared to be uniform across both dressings. - 3. Fluid removal rates were recorded to determine the wound exudate removal rate between the Kevo NPWT- αHemo30 Foam Dressing Kit and the Genadyne A4-XLR8 Foam Dressing Kit using plasma to simulate wound exudate. Suction was continuous for the entire 72 hour study. Fluid removal rate was found to be substantially equivalent. Additional tests were performed to further validate the substantial equivalence of the Kevo NPWT- «Hemo30 Foam and the predicated Genadyne A4-XLR8 Foam during its intended use *: - 4. Foam Comparisons under constant negative pressure (125mmHg) using the Genadyne A4 wound Vacuum over 72 hours. - 5. Foam Comparisons under variable negative pressure (150mmHg, 0mmHg) using the Genadyne A4 wound Vacuum over 72 hours. - 6. Foam Comparisons using optical measurement of cell size. * Synthetic blood O+ (code 70-016) from Carolina Biological was used as a replacement for wound exudate. {3}------------------------------------------------ #### Summary of Biocompatibility Compliance Tests 807.92(b)(2) · - ISO 10993-5 L929 MEM Elution Test . - ISO 10993-10 Intracutaneous Injection Test . - .
