Cardiopulmonary Bypass (CPB) Cannulas are specifically designed to facilitate veno-venous and veno-arterial access during extracorporeal circulation (e.g., cardiopulmonary bypass, ECMO, or short-term mechanical circulatory support). Engineered for peripheral vessel cannulation, these cannulas offer a secure, reliable, and minimally invasive interface between the patient’s vascular system and the extracorporeal circuit, ensuring stable blood flow for a wide array of cardiac and respiratory interventions.
Anatomically Informed Profiles
•Smooth Tapered Tips: Reduce vascular trauma and simplify vessel insertion.
•Ergonomic Shaft Curvature: Aligns with standard venous or arterial anatomy (e.g., femoral, jugular, subclavian), minimizing the risk of kinking or malposition.
Wide Lumen Variants
•Enhanced Flow Capacity: Allows efficient blood drainage and return for veno-venous or veno-arterial support.
•Optimized Pressure Dynamics: Maintains adequate flow rates with minimal resistance, essential for stable hemodynamic management.
Bio-Compatible Materials
•Medical-Grade Polymer: Ensures low thrombogenic potential, durability, and resistance to tear or puncture.
•Integrated Reinforcement (optional, depending on model): Offers added torque control and kink resistance during cannula positioning.
Secure Connection Hub
•ISO-Standard Connectors: Provide a leak-proof interface to the extracorporeal circuit’s tubing and pumps.
•Smooth Transition: Minimizes shear forces on blood cells, lowering hemolysis risk.
