Medical technology specialist Avant Medical (San Diego, California / USA; http://avantmedical.com) is currently developing a new generation of its Pulse Injection technology for needleless injection of medications. The materials being used include "Makrolon Rx2530" polycarbonate, according to Bayer MaterialScience (BMS, Leverkusen / Germany; www.bayerbms.com). Technical support from BMS is a key element in optimising the moulds, especially to ensure that the new nozzles can withstand up to 45 impacts, Avant Medical says.

Avant Medical’s new Gen3 injector is designed for patients who frequently have to self-administer medication. Up to 30 doses can be stored in a single reservoir and the appliance is also suitable for use by medical professionals in hospitals. The Pulse Injection system is based on vacuum stabilisation and two-stage delivery. Each dose is delivered through a cassette made of Makrolon. The injector provides a fluid pathway for the drug and generates a pulse that injects it through the skin.

According to Bayer MaterialScience, Makrolon is increasingly being used for plastic components in medical appliances. Other applications include micro forceps and scissors for ophthalmic surgery and portable mini-injection pumps.
