Abstract: Segmented scaffolds composed of disconnected scaffold segments are delivered to an implant site on a delivery balloon. The segments are crimped to the balloon and separated from each other by gaps. When the balloon is inflated the gaps between the disconnected scaffold segments stay constant. Pillowed or banded balloons are used to deliver the segments.

Abstract: 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 having a telescoping plenum which provides a drying chamber for the stent or scaffold to reside while a heated gas is passed over the stent/scaffold. The drying chamber 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 40 mm in length.
