Abstract
A guide wire that can be placed in a patient's vasculature or body cavity. The guide wire includes one or more radiopaque markers that can be visualized by fluoroscopy or the like. The markers are preferably spaced apart longitudinally along the guide wire such that the markers and/or spaces between the markers can be used to make measurements of anatomical or artificial structures within the body.
