conform in vivo to internal body contours thermoset materials such as silicone cannot be so modified catheter 10 is comprised of a distal portion 12 which as later explained will extend into the peritoneal cavity of the patient and a proximal portion 14 as will be later explained a first segment 14 39 of proximal portion 14 passes through the subcutaneous and cutaneous tissue of a patient whereas a second segment 14 34 extends externally from the patient and downwardly along the external abdominal wall of the suprapubic region of the abdomen distal portion 12 includes a distal end 16 which in a preferred embodiment comprises a spiral or coiled configuration 18 which lies in a single plane when the catheter is in a natural unstressed condition spiral 18 includes a plurality of openings 20 which permits passage of fluid such as a dialysate proximal portion 14 has a proximal end 22 which may be coupled to a source of dialysate or a container for dialysate drainage in all embodiments of the present invention distal portion 12 and proximal portion 14 are preferably linear in configuration as best disclosed in fig3 distal portion 12 and proximal portion 14 are linked by a linear connecting portion 24 connecting portion 24 has a length preferably about one centimeter which is substantially co extensive with the thickness.
