Abstract
A collapsible treatment device (81) for treating a target area of a vessel wall within a human or animal body, having a mesh portion, preferably annular in shape (82) and with a contracted configuration allowing travel within the vessel to the target area and an expanded configuration allowing treatment of the target area. A treatment implement is on the mesh portion and protuberance either as part of the mesh or provided on a sheath which protects the vessel from contact with the implement during travel within the vessel.
