Abstract: An implantable fluid shunting apparatus having a tube and a shunt tip attached to the tube end, that tapers towards the end of the shunt tip, a tip lumen extending through the shunt tip in fluid communication with the tube lumen, wherein the tip lumen has a closed end, and has a wall that comprises laser-ablatable material such that an opening can be formed through the wall and into the tip lumen using laser energy on an outer surface of the shunt tip. The shunt tip may consist essentially of the laser-ablatable material; the tube end is attached to an implantable diffusion chamber and the laser-ablatable material may be polypropylene. The tube and the shunt tip may be a one-piece completely integral unit or may be of separate bodies fitted together frictionally adhesively, thermally or chemically welded to the tube.
