Abstract
A shunt includes a housing having an inlet, an outlet and a flow control mechanism disposed within the housing. A ventricular catheter is connected to the inlet of the housing. The catheter has a longitudinal length, a proximal end, a distal end, and an inner lumen extending therethrough. The inner lumen of the catheter includes at least two lumens at the distal end and has only one lumen at the proximal end. The catheter has one slit and aperture corresponding to each of the at least two lumens located at the distal end of the catheter.
