ABSTRACT:
A method of manufacturing a drug loaded stent includes applying a photo resistant coating to at least a portion of a stent framework and removing at least a portion of the photo resistant coating from the stent framework. The method further includes applying an etchant to at least a portion of the stent framework and forming a plurality undercut drug reservoirs in the stent framework based on applying the etchant. A stent for treating a vascular condition includes a stent framework, a plurality of undercut reservoirs formed within the stent framework and a therapeutic agent disposed within at least a portion of the plurality of undercut reservoirs.
