Italian Plan 1 Health chooses Solvay's PSU

The Italian designer and manufacturer of implantable dental and infusion systems Plan 1 Health (located in Amaro, near Udine) chose Eviva polysulfone (PSU) from Solvay Specialty Polymers for the production of their implantable catheter ports, named Healthport. This resin was selected thanks to its biocompatibility, dimensional stability and MRI (Magnetic Resonance Imaging)compatibility.
Healthport catheter port system is multi-piece assembly consisting of an injection moulded housing and ring component, both made of Eviva PSU, and a titanium inner chamber. It is used for delivery of drugs, antibiotics and nutrient solutions. The PLP (Plastics Low Profile) model is lighter and more cost-effective than previous all-titanium versions which require more expensive manufacturing techniques. It features a low-profile PSU housing that is suitable for all patients. The titanium inner chamber, fixed between the two plastic components that are ultrasonically welded together, avoids damage induced by the needle tip and avoids interactions between Eviva PSU and the drug. A large self-sealing septum facilitates location during skin palpation and reduces the risk of puncture concentration. A transparent polyurethane connector allows a rapid, safe, and reversible connection of the catheter.
Eviva PSU maintains its dimensional tolerance right out of the mould and requires no machining. It is a rigid thermoplastic that doesn't absorb fluids and is artifact-free for effective MRI imaging.
The catheter ports – sold to medical device distributors in Europe, Asia, and India – have earned the CE (Conformité Européenne) mark which demonstrates compliance with numerous EC directives, enabling the product to be sold throughout the Euro region.
