Recent innovations in DES stents show promise. Biodegradable polymer drug-eluting stents, for example, offer a better safety profile than durable-polymer drug-eluting stents, as late-stent thrombosis is largely attributed to the polymer that binds the drug to the stent. In biodegradable polymer stents, a polymer controls drug release but then disappears, leaving a bare metal stent. Examples of stents with biodegradable polymers are Biosensors Internationals BioMatrix, Terumo Medicals Nobori, Sahajanand Medical Technologies Supralimus and Boston Scientifics fourth generation Synergy stent, which is still in development.
In contrast to bioabsorbable polymer stents, which still leave behind a bare metal stent, bioresorbable vascular scaffolds disappear completely, with the promise of vessel wall regrowth. A number of companies are working on scaffold products, including Abbott Vascular with ABSORB, REVA Medical with ReZolve, OrbusNeich and BIOTRONIK. Bioresorbable scaffolds were soft launched in 2011, and a full launch is expected across Europe by the end of 2012.
"These bioresorbable devices have the potential to revolutionize the market," said MRG Principal Analyst Karene Dumoulin. "They do need to demonstrate that they yield a decrease in the occurrence of late stent thrombosis or provide other advantages not available with current DES on the market, such as complete vascular restoration and motion, which is promised by Abbott Vasculars ABSORB device."
