Abstract:

A medical applicator assembly for a chain cystourethrographic procedure requiring only a single catheterization comprises a flexible intra-medic plastic tubing having a hollow longitudinal passage with coaxial proximal and distal openings at opposite ends, a metallic bead chain loosely and slideably positioned within the passage and having a soft tip secured to the proximal end of the chain, the tip comprising a stem portion slideably received within the proximal end opening of the passage and an integral head portion of larger diameter than the passage and of blunt tapered configuration and a flexible rod-like plunger of substantially smaller diameter than the passage for slideably displacing the chain relative to the tubing so as to dislodge the stem portion from the proximal opening of the tubing.
