Embodiment Construction

[0036] Detailed description of the preferred embodiment

[0037] While the present invention can be embodied in many different forms, the preferred embodiments have been described herein and shown in the drawings. The principles of the invention are illustrated herein without limiting the broad aspects of the invention to the illustrated implementation forms.

[0038] A novel catheter 10 according to the principles of the present invention is illustrated below by way of example in FIG. 1 . Catheter 10 is implanted into the peritoneal cavity of a patient for performing peritoneal dialysis. see also figure 2 , the catheter 10 is partially indicated in dashed lines for implantation into the patient 12 . Dialysis fluid can be introduced into and removed from the peritoneal cavity by means of the catheter 10 . In particular, catheter 10 enables continuous flow peritoneal dialysis treatment. To repeat, continuous flow peritoneal dialysis refers to the simultaneous flow of dialysa...

Abstract

A catheter suitable for use in performing peritoneal dialysis. The catheter is a dual lumen catheter which allows for continuous flow peritoneal dialysis. Dialysate flows through the catheter into the patient via one lumen and simultaneously flows through the catheter out of the patient via the second lumen. The dual lumen dialysis catheter has a flexible tube which has an implantable portion extending from an external patient portion. Both of the lumens have openings in the external patient portion for connecting to a supply and drain of dialysate, respectively. The implantable portion has a preformed curved segment which has an outlet for the first lumen to flow dialysate into the patient's peritoneal cavity. The implantable portion has an opening for the second lumen at the distal end to flow dialysate out of the peritoneal cavity and removal from the patient. The catheter facilitates mixing of fresh and spent dialysate inside the peritoneal cavity by inflowing fresh dialysate into the cavity at a location substantially separated from the cavity outflow location, and by directing the inflow of dialysate into the cavity opposite the cavity outflow location.

Description

technical field [0001] The present invention relates to catheters, and more particularly, the present invention relates to dual lumen catheters having two fluid flow paths. The catheter may be used in peritoneal dialysis to simultaneously infuse and drain dialysate from a patient. The invention also relates to methods of implanting and using catheters. technical background [0002] Kidney failure and poor kidney function are treated with dialysis. Dialysis removes waste, toxins, and excess water from the body that are removed by the kidneys when they are functioning normally. Dialysis treatment, which replaces kidney function, is life-threatening for many patients because it can save lives. Patients with renal failure cannot sustain life without at least partial replacement of the kidney's filtering function. [0003] Hemodialysis and peritoneal dialysis are two commonly used dialysis methods to treat renal failure. Hemodialysis treatment uses the patient's blood to rem...
