Abstract

A catheter (16) with a centering tip (14) to maintain the catheter in the center of a blood vessel during insertion. A porous section (17) is provided as a disharge port on either the catheter or tip, or both to create a bolus of injectate, reducing the amount of injectate necessary for imaging ructions.
