Polymer Solution Casting

Cannulae & Catheters

Nordson MEDICAL is the world's leading contract manufacturer of cardiopulmonary vascular cannulae, catheters, and specialized medical tubing for a wide range of clinical applications. The key is our Avalon Laboratories polymer solution casting technology, which allows us to design and manufacture custom tubing with features not achievable by conventional extrusion or injection molding, at less cost.

Many Properties; One Device

Applying liquid polymers in layers allows us to combine into one device materials with different properties including strength, lubricity, and flexibility. This technique allows varying wall thicknesses and diameters along the length of the device in a single-piece construction, while maintaining tight tolerances. We can also add reinforcement for flexibility, kink resistance, and maneuverability. Polymer solution casting results in thin walls, high flow, and superior column strength for enhanced performance.
