DUKE Extrusion can produce multi-durometer catheter shaft and medical device tubing that provides 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. Up to six different materials can be used 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 imbedded into the tubing to indicate different durometers. Swaging for electrodes can be included on the outside surface, and ends can be tipped with radiopaque materials.
DUKE Extrusion offers design assistance to help you develop the right multi-durometer tubing for your catheter manufacturing application.
