Abstract
A catheter for placement into the ventricular system of the brain of a subject comprising a flexible elongated body having a wall thickness sufficient to contain and transport fluid therein and having 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, each of the apertures extending through the wall thickness at an angle such that a portion of the wall thickness is visible when viewing the aperture perpendicular to the longitudinal axis of the body, thereby to minimize abrasion of brain tissue upon insertion of the catheter and to prevent choroid plexus and ependymal tissue from growing into the catheter apertures, thereby providing improved flow of fluid into or from said ventricular system. Also, methods of using and apparatus for making such catheters are disclosed herein.
