摘要:
A method and apparatus for locating the injection point of an implanted medical device. In a preferred embodiment, the locating apparatus is in the form of radiopaque rings made of a metallic substance. When these rings are spaced apart at different heights on an implanted medical device, such as a drug port, a stereoscopic effect results from fluoroscopically viewing the device along an axis not parallel to the axis along which the rings are spaced. This effect allows one to readily determine the orientation of the device. This prevents accidental injection of drugs into the hard backside of the drug port.
