The Phoenix Lumbo Peritoneal shunt system is designed for the diversion of CSF from the subarachnoid space into the peritoneal cavity. It is available in three configurations, LPS1, LPT1 and LPY1.

The graph on the right demonstrates the mean pressure / flow characteristics for the LPS1, LPT1 and the LPY1.

LPS1, the standard Straight tube, is a 90 cm barium impregnated catheter. The lumbar end of the catheter has 12 drainage holes and the tip is angled 45O. The peritoneal end of the catheter is a closed tip with side slits to prevent reflux. The distal tip of the catheter is made with radiopaque tantalum. The lumbar end of the catheter has measurement dots at 11.5 (the distance from touhy needle tip to end of touhy needle), 12 cm and at 1 cm increments up tp 20 cm. The peritoneal end of the catheter has measurement dots starting at 5 cm & at 5 cm increments to 30 cm. The shunt comes with a Touhy needle and a suture tab.
