Abstract
An obturator for use with a conventional sheath introducer or any other tubular member providing access to the interior of the body of a living being. The obturator comprises a shaft in the form of an elongated rod-like element having a distal end. The rod-like element is formed of a first material, e.g., polyester based polyurethane, having a first durometer, e.g., 75 (Shore D). The distal end of the rod like element is in the form of a tip formed of a second material, e.g., aliphatic polyurethane, having a second durometer, e.g., 80 (Shore A), substantially less than that of the first material. The tip is a hollow tubular body having a domed free end. The distal end of the rod-like element includes an annular recess about its periphery which cooperates with the mating shaped hollow interior surface of the tip to secure the tip in place. A radiopaque material, e.g., barium sulfate in a concentration of at least 20 percent by weight, is incorporated into the tip to facilitate radiographic location of the obturator when it is in place within the body of the being.
