Abstract

Peritoneal dialysis systems, methods, and catheters are provided for performing peritoneal dialysis therapies. Multiple fluid pathways are provided to a patient'"'"'s peritoneal cavity for conveying dialysis fluid to and from the patient.

Claims

1. A peritoneal dialysis catheter implantable in a peritoneal cavity of a patient, comprising:

a tube having first and second lumens, the tube extending from a first end to an implantable portion having a single free end;

a fluid opening to the first lumen located between the first end and the single free end; and

a fluid opening to the second lumen located at the single free end, the single free end having a non-linear shape.

2. The peritoneal dialysis catheter of claim 1, wherein the tube is so positioned and arranged when in use in the peritoneal cavity that fluid flows through both the first and second lumens during patient fill.

3. The peritoneal dialysis catheter of claim 2, wherein the tube is so positioned and arranged when in use in the peritoneal cavity that fluid flows through both the first and second lumens during patient drain.

4. The peritoneal dialysis catheter of claim 1, wherein the tube is so positioned and arranged when in use in the peritoneal cavity that fluid flows through both the first and second lumens during patient drain.

5. The peritoneal dialysis catheter of claim 2, wherein the tube is so positioned and arranged when in use in the peritoneal cavity that one of the first and second lumens delivers fluid to the patient and another one of the first and second lumens drains fluid from the patient.

6. The peritoneal dialysis catheter of claim 1, wherein the tube is a single tube having the first and second lumens.

7. The peritoneal dialysis catheter of claim 1, wherein the single free end has a coiled shape.
