Abstract
A drainage catheter includes a shaft having a flexible distal portion to be anchored in a cavity of a patient and a proximal portion attached to a hub. The hub includes a side port with a deformable sealing insert having self-sealing passageways for tensioning members, such as nylon filaments, passing through the catheter shaft and exiting the side port. The tensioning members are pulled proximally to deform and thereby anchor the distal portion of the catheter. Excess filament length is wrapped around a resilient pinch washer and held inside a groove in the pinch washer, with the groove thereafter compressed by a C-clip to secure the excess filament length inside the groove.
