A catheter for placement into the ventricular system of the brain or any other member or cavity of the body of a subject comprising a flexible elongated body having a non-circular bore, a wall thickness sufficient to contain and transport fluid therein, a forward end and tip for insertion into the ventricular system of the brain of a subject, and a plurality of spaced apertures located in the forward end of the body spaced from the tip. The apertures are configured and positioned to minimize abrasion of brain tissue upon insertion of the catheter and to prevent tissue from growing into the catheter apertures, thereby providing improved flow of fluid into or from said ventricular system. The non-circular bore, preferably triangular, provides increased structural integrity and increased effective flow through the catheter compared to those having a circular bore. Also methods of using such catheters are disclosed herein.
