Catheter
First Claim
1. A continuous flow catheter, said catheter comprising at least two independent lumens, each of said at least two independent lumens having a proximal end and a distal end region, each of the distal end regions of each of said at least two independent lumens comprising at least one opening for the passage of matter into or out of the body of the user of the catheter, at least one of said at least two independent lumens being a first lumen and at least one of said at least two independent lumens being a second lumen, said second lumen being longer than said first lumen, wherein said distal end region of said second lumen is coiled.

Abstract
Continuous flow catheters, diffusers for catheters, catheters having a diffuser, and methods for continuous flow peritoneal dialysis are provided. The continuous flow catheter includes at least two lumens, of which one is short and the other is long. The long lumen is coiled and contains a plurality of openings. Another similar continuous flow catheter also includes a diffuser for the dispensing of fluid in a diffused manner. The catheters are used for peritoneal dialysis. The diffuser, for use with a catheter, has a plurality of openings for the dispensing of matter in a diffused manner. One method for continuous flow peritoneal dialysis includes creating an incision in the body of the user and separating the anatomical layers, making a circular suture in the peritoneal membrane, making an incision in the peritoneal membrane, inserting the catheter, and tightening the parietal peritoneum. Another method additionally includes anesthetizing the skin and peritoneal surface, making a lateral incision in the skin of the user, creating a skin tunnel, passing the catheter through the skin tunnel, connecting attachments to the catheter, and suturing the skin incision. The methods also include providing a catheter having a diffuser.
