Figure 1 – Tenckhoff Catheter
Oreopoulos Zellerman or TWH catheter is shown at the bottom. To decrease leaks they strengthen the seal at the internal cuff by providing a flange and a bead. A purse string suture between the bead and the flange provides an extremely strong seal almost completely preventing pericatheter leaks. Intraperitoneal tubing was provided with two silicone rubber discs to prevent catheter migration, omental wrap and obstruction.
