Nexus Venous & Arterial Cannula
Multipurpose venous and arterial cannulae supporting extracorporeal circulation during cardiopulmonary bypass or ECMO, ensuring optimal flow rates and hemocompatibility.
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.
