<p>A non-metallic catheter button body having a variety of geometric shapes, having integrally secured therewith a metallic marker element, to anchor a catheter or surgical tube in the body with less pain to the patient while providing an X-ray visible marker, which button substantially reduces loss of the patient's skin from scattered electrons resulting from a bombardment by radiation from radioactive material. The non-metallic button body may further include an integral non-metallic stem portion to facilitate the crimping of the stem, anchoring of tubes in the body, and insertion of ribbons of radioactive material therein.</p> |
