New polymer systems will be featured players in a bevy of new drug-eluting stents set to enter the market. The stents are placed in blood vessels close to the heart with the intent of releasing drugs that keep arteries open with patients who suffer from arteriosclerosis. It’s become a multi-billion dollar business with a couple of star players, and a spectacular technology display for high tech plastics. One of the exciting new entries features a bioresorbale polymer, first predicted by Design News. This is a plastic that disintegrates within six months, leaving just the cobalt chromium metal stent to prop open the artery. It comes in the Costar system from Conor Medical Systems. Conor was recently acquired by J&J. Abbott is developing a stent that is made of bioresobrale resin, specifically polylactic acid (PLA). It isn’t expected to hit the market for another five years. The new technologies in the stent business were reviewed yesterday at a cardiology meeting called CRT 2007 (Cardiovascular Revascularization Therapies) in Washington DC. My take: It will take a longer for new exciting technologies to make it to the operating table because of lingering questions about the effects of the original drug-eluting polymer stents. The questions focus more on the drugs than the polymers, but this one of the most exciting technology development areas for plastics on the planet.
Some of the biggest self-assembled building blocks and structures made from engineered DNA have been developed by researchers at Harvard's Wyss Institute. The largest, a hexagonal prism, is one-tenth the size of an average bacterium.
Arevo Labs' end-production 3D printing technology for carbon composites includes a high-temperature, filament fusion printer head design and firmware for use with the company's new carbon fiber and nanotube reinforced high-temperature matrix polymers like PEEK.
Stratasys will buy Solid Concepts and Harvest Technologies and combine them with its RedEye service business. The plan takes aim at end-production manufacturing and will create one of the biggest commercial 3D printing and AM service bureaus.
The International Federation of Robotics reports that global sales of industrial robots decreased by 4% in 2012 over 2011. The biggest hit was electrical/electronics manufacturing, down by 13%; but by region, the Amerficas did well.
