Nexus Venous & Arterial Cannula

Nexus Venous & Arterial Cannula

Multipurpose venous και arterial cannulae supporting extracorporeal circulation during cardiopulmonary bypass or ECMO, ensuring optimal flow rates και hemocompatibility.

Πληροφορίες

Cardiopulmonary Bypass (CPB) Cannulas are specifically designed to facilitate veno-venous και veno-arterial access during extracorporeal circulation (e.g., cardiopulmonary bypass, ECMO, ή short-term mechanical circulatory support). Engineered for peripheral vessel cannulation, these cannulas offer a ασφαλές, αξιόπιστο, και ελάχιστα επεμβατική interface between the patient’s vascular system and the extracorporeal circuit, ensuring stable blood flow for a wide array of cardiac and respiratory παρεμβάσεις.

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.
  • Enhanced Flow Capacity: Allows efficient blood drainage and return for veno-venous ή veno-arterial support.
  • Optimized Pressure Dynamics: Maintains adequate flow rates with minimal resistance, essential for stable hemodynamic management.
  • Medical-Grade Polymer: Ensures low thrombogenic potential, durability, and resistance to tear or puncture.
  • Integrated Reinforcement (optional, depending on model): Offers added torque control και kink resistance during cannula positioning.
  • 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.
