Balloon Catheter Tubing
TekniPlex Healthcare, Wayne PA, offers PTA/PTCA balloon catheter tubing solutions, which are ISO 13485-certified and manufactured at the company’s Suzhou facility. Ranging in balloon size from 1 to 30 mm, the customized balloon catheter tubing is manufactured at tight tolerances (±0.0005 in.) with concentricity of over 90 percent. The tubing’s controlled elongation rate provides blown balloons with uniform wall thickness, improving overall yield and substantially reducing bursting risk. The trilayer inner tubing consist of polyamide (nylon) or polyether block amide copolymer (PEBA) outer layers with high-density polyethylene (HDPE) inner layers. The small-diameter, thin-wall, tight-tolerance configurations are required for use in interventional vascular apparatuses to allow diagnostic and therapeutic devices to more easily advance over guidewires.

Biopharmaceutical Tubing
Kent Elastomer Products, Kent, OH, has released a biopharmaceutical tubing that can replace thermoplastic elastomers and is designed to reduce emissions related to single-use tubing by as much as 50 percent. In addition, an eco-TPE biopharmaceutical tubing is available. Both options offer minimized leachables and extractables, high burst strength, extended pump life, and chemical resistance. The tubing can withstand the rigorous pressures and stresses encountered during fluid transfer and increased solids during peristaltic pumping operations.

Peelable Heat Shrink Tubing
Cut-to-length and slit peelable heat shrink tubing is available from Junkosha, Tokyo, Japan. Designed to streamline manufacturing processes such as balloon bonding and reflow processing, the peelable tubing enables manufacturers to efficiently repair and refine components such as shafts and balloons, minimizing waste and reducing costs. The custom solution also supports precision masking during catheter coating. Unlike traditional heat shrink tubing, the peelable technology eliminates the need for skiving the heat shrink material from the catheter after the reflow process, reducing both the time required to take this step and also the risk of damaging the underlying catheter.

Ultra Polyimide
Confluent Medical Technologies, Scottsdale, AZ, has launched a material that delivers nearly twice the strength of traditional polyimide. Ultra Polyimide reduces material usage while maintaining essential column and tensile strength. The material is manufactured without the use of REACH- or EU MDR-restricted solvents, including NMP (n-Methyl-2-pyrrolidone). By eliminating NMP from its manufacturing process, the company ensures regulatory compliance, enhances workplace and patient safety, and protects the long-term stability of the medical device supply chain.
