Figure 3 – Bead/flange relation to the peritoneum
This slide shows the bead/flange relation to the peritoneum. A purse string between the flange and the bead creates an extremely tight seal around the catheter. A slanted bead and flange preserve better downward direction of the intraperitoneal segment of the tubing. Downward direction of the intraperitoneal entrance decreases the rate of catheter migrations.
