Tekni-Plex business Dunn Industries is highlighting its acetal Catheter Core mandrel technology at this year’s MD&M West.

The technology is used to manufacture minimally invasive catheter shafts. The products are used to retain lumen tolerance during extrusion, braiding, coiling and jacketing processes. Low friction material properties and ultra-smooth surfaces allow these cores to be easily removed after catheter shaft assembly. They are available in precise diameters from 0.020 to 0.250 inches with tolerances as low as +/- 0.0005 inches.

Reinforced tubing is used for diagnostic and guide catheters, high-pressure contrast injection tubing and other minimally invasive devices. Adding reinforcement to the plastic tube wall improves torque transmission, kink and internal pressure resistance, and column strength.

Dunn also manufactures custom medical tubing for diagnostic and interventional devices from thermoplastics. These include polyether block amides (PEBAs), thermoplastic polyurethanes (TPUs), thermoplastic elastomers (TPEs), polyamides and polyolefins.

The technology is on show at the Anaheim Convention Center, California, at Booth 2033 at MD&M West until 7 February.
