A cholangiographic catheter is provided for delivering a contrast fluid for use in X-rays. The device comprises an elongated tube with a curved section. The curved section has a tapered tip and a means for discharging a fluid in a directional flow for reaching the proximal or intraheptic bile ducts as well as the duodenum. In a preferred embodiment, the catheter would have a first set of holes on the curved section and a second set of holes that are smaller than the first located below the first. This would allow for greater control of dispersion of contrast fluid used in X-rays. The catheter would be made of a medical elastomer with memory so that the catheter may maintain the shape of the curved section after the catheter has been inserted into the body.
