摘要:
A system for treating a vascular condition includes a catheter, a stent disposed on the catheter, the stent having a stent framework including a stent wire and at least one stent foil attached to and wrapped around the stent wire, and a therapeutic agent coating disposed on an inner surface of the at least one stent foil. A method of manufacturing a stent includes securing a first edge of a stent foil to a stent wire, applying a therapeutic agent coating to an inner surface of the stent foil and wrapping the coated stent foil around the stent wire to encase the coating between the stent foil and the outer surface of the stent wire, securing a second edge of the wrapped stent foil to the stent wire, forming at least one exit port along the secured second edge and forming the wrapped stent wire into a stent framework.
