Arterial Filters are essential inline devices used in cardiopulmonary bypass (CPB) circuits during cardiac and vascular surgeries to safeguard patients from microemboli and particulate matter. Constructed with high-efficiency, depth-type polyester mesh screens (typically 20-40 micron pore size), they effectively capture air bubbles, fat globules, platelet aggregates, and debris from arterial blood flow, preventing stroke, organ damage, and postoperative complications. Featuring biocompatible polycarbonate housings, hydrophobic venting membranes, and pressure-resistant designs (up to 500 mmHg), these sterile, single-use filters ensure unobstructed flow rates of 4-6 L/min while minimizing priming volumes (50-250 mL). Integrated Luer ports allow sampling and priming, supporting safe perfusion in adult and pediatric procedures for optimal outcomes.
