ABSTRACT:
A catheter for introducing fluid into the vascular system includes ports in the catheter's sidewall which are obliquely angled with respect to the longitudinal axis of the catheter. Certain pairs of ports are oriented toward each other, and certain other pairs of ports are oriented away from each other. The arrangement of ports causes fluid to exit the ports in streams which are oriented at oblique angles corresponding to the angles of the port. The obliquely angled streams create advantageous circulation paths proximate to the catheter which generally improve efficacy of the injected fluid associated with the medical application. The catheter may be used for a variety of purposes, including to perform thrombolysis.
