A catheter for use in continuous flow peritoneal dialysis comprising an inflow tube and an outflow tube, wherein both are connected on one end to a dialysis machine. The inflow tube is divided into a plurality of smaller inflow auxiliary tubes, and the outflow tube is divided into a plurality of smaller outflow auxiliary tubes. 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. The auxiliary tubes are covered by a sheath prior to implantation, which is then removed, thereby deploying, preferably into an open-basket shape, the auxiliary tubes within the peritoneal cavity which separate to allow for the continuous flow of dialysis solution. This reduces the time required to complete the procedure and increases its efficiency by reaching a larger surface area of the peritoneal cavity, all without kinking or blocking.
