1. The method of making a record of the venous plexus system of a uterus which comprises inserting into the uterus a tubular shaped instrument having a hollow core and a rounded probing end, probing with the instrument to locate the fundus with the rounded end, inserting a hollow needle having a piercing point and an opening through the center of said needle into the hollow core of the tubular instrument to penetrate the surface of the fundus, restraining the needle so that said penetration occurs only to a predetermined depth into but not through the wall of the uterus, injecting x-ray opaque material into the opening in the needle so that it passes through the needle into the spongy layer of said uterus and then exposing an x-ray film to record the passage of said x-ray opaque material through the venous plexus system of the uterus on the x-ray film.
