DRYERS FOR REMOVING SOLVENT FROM A DRUG-ELUTING COATING APPLIED TO MEDICAL DEVICES

摘要

A coating device for coating a medical device with a drug-eluting material uses an in- process drying station between coats to improve a drug release profile. The drying station includes a dryer (10) having a telescoping plenum which provides a drying chamber (32) for the stent or scaffold to reside while a heated gas is passed over the stent/ scaffold. The drying chamber (32) improves efficiency in drying, predictability or drug release rate, uniformity of coating material properties lengthwise over the stent/scaffold and provides a platform that can effectively support stents that are over 40mm in length.
