Tekni-Plex business, Dunn Industries presented its latest tubing solutions for endovascular catheters at Medtec China in September.
The Chinese market is currently after solutions from tubing suppliers to develop diagnostic and interventional devices used in endovascular procedures.
Endovascular surgery, which is performed within the blood vessels, is commonly used to treat aneurysms, narrowing areas and blockages, whilst also being used to deliver replacement heart vales and more. Procedures involve catheters being inserted into femoral or radial arteries and moved to the required vascular site using x-ray imaging.
Endovascular catheters rely upon unique properties of select thermoplastics and thermoplastic elastomers (TPEs) to produce high strength and flexibility thin-wall catheter tubing. These include thermoplastic urethanes (TPUs), polyether block amides (PEBA), polyamides, and polyolefins.
“Medical device companies are designing catheters with smaller dimensions and tighter tolerances, and requesting quick turnaround on prototypes to accelerate time-to-market. Fast lead times on precision extrusions and the ability to quickly scale to production quantities are hallmarks of our service offering,” said Dan Lazas, Tekni-Plex senior director of medical components.
