Abstract
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-locksble 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.

Plate 7 h~s apertures therein evenly spaced about the perimeter of the housing for suturing the device to a layer of tissue when implantingO Also shown in Figure 1 is a syringe 9 having a non-coring needle 10. Syringe 9 is shown by way of illustration having penetra~ed the septum or cover 3, in position to refill the re~ervoir. A catheter 11 leads from the reservoir to the vascular system of the subject.
Figure 2 shows a sch~matic section of the device 1 implanted beneath the skin of a mammal. As sho~n, device 1 lies beneath the skin 12 in the sub-cutaneous tissue 13 of the mammal. One or more sutures L4 through apertures 8 o~ t~e ~5 baseplate attach device 1 to ~he muscle ~ascia 15, and catheter 11 leads from the housing to l:he vascular system 16 of the mammal. The housing 2 of devlce 1 has a low profile and a broad flat base.

Connector 17 comprises a peripheral flange portion 18 and a centr~ll por~ion l9 having a bore 30 there through ~or fitting over a catheter in such a manner as to be slideably moved therealong. Flange 18 compr~ses opposea arcuate flange segments 18A, 18B extending radially outward from central portion l9. Flange 18 has a minimum cross-dimension dl in a first direction and a maximum cross-dimension d~ in a secontl d~rection angularly offset therefromO Connector 17 also includes a tab 27, discussed urther below in relation to }~igure 5.
