Reinforced Polyimide Tubing

Braid and coil-reinforced polyimide tubing from Zeus, Orangeburg, SC, helps medical device engineers optimize their catheter designs and fine-tune key performance characteristics, paving the way for improved procedural outcomes and increased patient safety. Reinforced polyimide tubing is available in full load and half load braid patterns, as well as in coil configurations. It is available with total wall thicknesses (inner layer plus reinforcement plus outer layer) as low as 0.002 in./0.051 mm and inside diameters (ID) down to 0.010 in./0.254 mm. Polyimide tubing provides excellent strength and abrasion resistance and maintains its properties at very small dimensions. For applications where additional lubricity is needed, a PI/PTFE composite provides a lower coefficient of friction.

Heat-Shrink Tubing

Junkosha, Gloucestershire, UK, has launched cut-to-length and slit peelable heat shrink tubing (PHST) for a wide range of catheter-based procedures where flexibility is the key requirement. Catheter delivery systems for neurovascular treatments rely on increasingly complex shapes, constructs, and polymers to deliver their intended treatment. This intricacy in catheter bonding and welding applications can only be consistently achieved through advanced technology innovations such as cut-to-length and slit PHST, which enables catheter manufacturers to use different lengths to not only reflow a catheter’s baseline materials, but also to attach complex shapes and constructions. Key application areas include balloon mounting, catheter lamination, forming, tacking, masking, bonding parallel tubes, and polymer jacket compression.
