Abstract
An external introducer for a ventricular catheter that is part of a hydrocephalus shunt system. The introducer includes a stylet assembly that mates with a cannula assembly. The cannula assembly comprises a cannula having a bent tip and an opening on the sidewall of the cannula, and a cannula hub into which a catheter is clipped. The stylet assembly includes a flexible stylet attached to a stylet hub. When the stylet hub is locked to the cannula hub, the stylet protrudes slightly from the end of the cannula at an angle. The introducer holds the catheter approximately straight for insertion into the ventricle of the brain.
