An implantable catheter is disclosed that is particularly useful as a peritoneal access device. The catheter includes an elongated, flexible tube, one portion of which is adapted to extend into the body of a user with a second portion external to the body of the user. The end of the one portion of the tube within the body has connected thereto a flexible terminating member comprised of a pair of spaced apart sheets extending outwardly of the periphery of the tube in a direction substantially normal to the axis of the end portion of the tube with the spaced sheets forming a passage therebetween communicating with the interior of the tube through a central opening in one of the sheets so that access to the tube is through the passage formed by the spaced sheets. In the disclosed embodiments, the sheets are either substantially flat discs held in spaced relationship with respect to one another by means of a plurality of columns extending between the discs or are apertured, curved sheets with opposite edges connected together. Columns of reduced diameter are also disclosed to enable folding of the discs to facilitate insertion into the body of a user.
