Published: with international search report (Art. 21(3)) (54) Title: SYSTEM AND METHOD FOR APPLYING MATERIAL TO A STENT (57) : Methods for applying polymeric material to a stent are disclosed. A mandrel is coupled to a stent body. The stent body comprises an inner surface defining a cavity and an outer surface opposing the internal surface. The stent body also has a length along an axis defined by the mandrel between a first end of the stent body and a second end of the stent body. An electrospun material is applied to at least a portion of the stent external surface and to at least a portion of the mandrel to form a coating sheet. A portion of the coatin g sheet extends from at least one of the first end or second end of the stent to the mandrel. One or both of the stent and the mandrel are moved to apply at least some of the portion of the coating sheet onto the internal surface of the stent body.
