1. A peritoneal dialysis catheter comprising:
a tube having an implantable portion extending from an external patient portion, the implantable portion having a preformed
curved segment between the external patient portion and a distal end of the implantable portion;
a first lumen extending through the tube from a first external port in the external patient portion to a first implantable
port formed in a sidewall of the curved segment of the implantable portion; and
a second lumen extending through the tube from a second external port in the external patient portion to a second implantable
port in the implantable portion;
a separation section, the separation section configured to space the second implantable port away from the first implantable
port a distance sufficient such that when implanted the first implantable port resides at an upper area of a patient's peritoneal
cavity and the second implantable port resides at a lower area of the peritoneal cavity, wherein the first lumen is sealed
proximal to the separation section.
