Duke Extrusion can produce multi-durometer catheter shafts and medical device tubing that provide a smooth transition from the distal portion to the proximal portion. This allows the tubing to track into target locations with sufficient support and the flexibility to navigate.
We utilize state-of-the-art custom equipment to create unique combinations of material for an optimal balance of flexibility and rigidity. We can use up to six different materials along the length for a gradual transition between high and low durometers. It is always best to use the fewest number of transitions that will still achieve the desired results.
Multi-durometer tubing can be shaped into fixed, curved paths, and can be extruded in an infinite variety of geometries to meet your unique requirements. Marker bands can be embedded into the tubing to indicate different durometers. We can include swaging for electrodes on the outside surface and can tip ends with radiopaque materials.
