In embodiments a stent includes a stent body and a wire-form carrying a drug located along the stent body.
What is claimed is: 1. A stent comprisinga stent body defining a lumen and a stent body surface, the stent body comprising a first metal, the stent body surface defined by a luminal surface, an abluminal surface, and at least two side surfaces of the stent body, anda wire-form formed of a second met
What is claimed is: 1. A stent comprisinga stent body defining a lumen and a stent body surface, the stent body comprising a first metal, the stent body surface defined by a luminal surface, an abluminal surface, and at least two side surfaces of the stent body, anda wire-form formed of a second metal, said wire-form carrying a drug and passing through and located along the stent body without substantially interfering with mechanical performance of the stent body, the second metal being bioerodible and different from the first metal of the stent body, thereby to encourage galvanic corrosion of the wire-form,the drug on the wire-form being decoupled from the stent body surface, anddelivery of the drug not being limited by geometry of the stent body or by position of the stent body surface against a vessel wall,wherein the stent body includes passageways formed therethrough, at least one passageway having an opening in at least one side surface of the stent body and extending along the longitudinal axis of the stent body, andwherein the wire-form passes through the passageways.
