Abstract
An implantable treatment device has a housing portion defining a chamber and a self-resealable cover portion which closes off the chamber to provide a fluid receiving reservoir. An exit port extends from the reservoir to the external surface of the housing, and a locking member affixed to the device permits a twist-lockable catheter connection to be securely sealed to the exit port. In one embodiment the locking member is a base plate having a slot therein to capture the flange of a catheter connection. A protruding tab on the catheter connection may be sutured to hold the twist-locked connection in a fixed orientation. A multi-reservoir and multi-catheter embodiment is shown. A preferred implantable multi-reservoir device includes tactile features palpable through the skin for distinguishing the different reservoirs, or identifying the contents thereof.
