Embodiment Construction

[0040] A description will now be given of the present invention with reference to FIGS. 1-7B. It should be understood that these drawings are exemplary in nature and are in no way intended to limit the scope of the invention, as the invention will be defined by the claims, as interpreted by the courts in issued U.S. patents .

[0041] Figure 1A A preferred embodiment of the present invention, a high open flux basket catheter (herein, "basket catheter") for efficient continuous flow peritoneal dialysis, as it would appear after full implantation and removal of the sheath like that. Peritoneal dialysis is a form of dialysis that involves the insertion of a tube into a patient's abdominal cavity to introduce a cleansing dialysis solution fluid called dialysate into the body. The abdominal wall lines the diaphragm known as the parietal peritoneum, and the bowel and other viscera line the peritoneum known as the visceral peritoneum. The parietal and visceral peritoneum are conti...

Abstract

A catheter for use in continuous flow peritoneal dialysis comprising an inflow tube and outflow tube, both connected on one end to a dialysis machine. The inflow tube is divided into a plurality of inflow auxiliary tubes, and the outflow tube is divided into a plurality of outflow auxiliary tubes, with all auxiliary tubes encased in a single external tube. The auxiliary tubes each contain a plurality of apertures for the rapid and efficient movement of dialysis solution in and out of the peritoneal cavity to reach a larger surface area without kinking or blocking. The external tube comprises a tunnel for insertion of a fiber optic borescope to view the dialysis procedure. The auxiliary tubes are covered by a sheath prior to implantation, which is then removed, deploying, preferably into an open-basket shape, the auxiliary tubes within the peritoneal cavity to allow for the continuous flow of dialysis solution.

Description

[0001] related application [0002] This application claims priority to US nonprovisional application serial numbers 13 / 592,712, filed August 23, 2012, and 13 / 961,918, filed August 8, 2013, the disclosures of which are incorporated herein by reference. technical field [0003] The present invention relates to a novel basket silicone dialysis catheter for providing high flow, efficient peritoneal dialysis to patients with end stage renal disease. A novel device to be used in continuous flow peritoneal dialysis is disclosed which maximizes the efficiency of the dialysis process while minimizing the time spent on such a dialysis process by utilizing multiple inflow and outflow tubes during the dialysis process . A novel peritoneal dialysis catheter device is presented. In use, the device will provide a high flux simultaneous inflow and outflow of dialysate during peritoneal dialysis. The present invention is preferably made of silicone rubber and a Dacron cuff for anchoring t...
