Abstract: A stent that is intended to be introduced into a human person has an elongated one-piece body with an outer wall of generally uniform thickness and with an exterior cylindrical surface. The body has a first longitudinally extending axis forming the center line for the cylindrical surface. A tubular passage is located within the interior of the body and has a second longitudinal axis which is parallel to and spaced from the first longitudinal axis. The passage has a generally cylindrical wall formed in part by the outer wall of the body. An elongated channel is located within the interior of the body and partially enclose the generally cylindrical wall of the tubular passage. The outer wall has an entrance slot therein for opening the channel. The slot is spaced from the cylindrical wall of the tubular passage. The passage, channel and slot each extending the entire length of the body.
