Abstract
A stylet includes an elongate body defining a passage and at least one aperture in fluid communication with the passage. The stylet also includes a first blocking dam secured to the elongate body proximal to the at least one aperture and a second blocking dam secured to the elongate body distal to the at least one aperture. The stylet is movable within a lumen of a catheter to a position in which the first and second blocking dams are, respectively, proximal and distal to at least one side opening of the catheter and each of the first and second blocking dams is sealingly engaged with an inner surface of the catheter such that fluid introduced into the lumen, from the passage and through the at least one aperture of the stylet, is directed through the at least one side opening of the catheter.
