Abstract
The present disclosure is directed to a stent manufacturing assembly including an inner shield, a patterned metal sheet, and an outer shield. The patterned metal sheet may include a polymer coating with an embedded therapeutic agent. The inner shield, patterned metal sheet, and outer shield are arranged in a layered configuration and placed in a stent rolling mechanism with a mandrel. In particular, the patterned metal sheet is disposed on the outer shield and the inner shield is disposed on the patterned metal sheet in the layered configuration. In the layered configuration, the stent manufacturing assembly is rolled by the rolling mechanism into a tubular shape and welded to form a tubular stent.
