LORTON, Va.--(BUSINESS WIRE)--Nano Interface Technology (NITI) expands application of its platform technology to solve the problem of the drug-coated stent using nanohydroxyapatite coating technology. The recently recognized problem with the drug-coated stents "late stent thrombosis" can be solved using NITI’s nanohydroxyapatite coating technology. The drug-eluting stent has been extremely successful in reducing restenosis from the 20-30% range to single digits. But the growing evidence suggests that drug-eluting stents may be susceptible to an event known as "late stent thrombosis", where blood-clotting on the stent can occur one or more years post-stent, leading to higher mortality. The main reason for late stent thrombosis is lack of endothelization of the stent. The presence of polymer and/or collagen in the coating delays and/or prevents endothelization of the stent surface.
