A flexible s.c. catheter used with the body provides communication between the body exterior and peritoneal cavity. - The body pref. holds a sealing elastomeric septum defining an excutaneous cavity in which is a sponge satd. with antiseptic soln. and a penetrable cap sealing the sponge in the body and having a slit through which a cannula can be inserted. The cap pref. has a conical centred depression on the exterior to form a needle guide.
