Abstract:
1. A catheter for use in continuous flow peritoneal dialysis, comprising: an inflow tube, comprising a length of tubing having an inner diameter and an outer diameter, said inflow tube divided into a plurality of separate inflow auxiliary tubes, said inflow auxiliary tubes configured to pass dialysis fluid directly from said inflow tube to a peritoneal cavity; and an outflow tube, comprising a length of tubing having an inner diameter and an outer diameter, said outflow tube divided into a plurality of separate outflow auxiliary tubes, said outflow auxiliary tubes configured to pass dialysis fluid directly from the peritoneal cavity to said outflow tube; wherein each of said inflow tube and said outflow tube has a proximal connection means for securing to a dialysis machine; wherein each of said inflow auxiliary tubes and said outflow auxiliary tubes contains a plurality of fluid-conveying apertures for simultaneous movement of dialysis fluid in and out of the peritoneal cavity; wherein at least a segment of said inflow auxiliary tubes and said outflow auxiliary tubes are encased in a single, outer tube, said outer tube further comprising a separate tube which is adapted for receipt of a fiber optic borescope for viewing the dialysis procedure; wherein said inflow auxiliary tubes and said outflow auxiliary tubes define an expandable open-basket shape, and wherein all of said auxiliary tubes are separate and connected at their distal ends by a non-traumatic end cap; and wherein said apertures on said inflow auxiliary tubes and said apertures on said outflow auxiliary tubes throughout the perimeter of said open-basket shape are configured to provide unobstructed free-flow of dialysis fluid throughout the peritoneal cavity while maximizing the surface area of the peritoneal cavity directly targeted by the dialysis fluid released from said apertures in said inflow auxiliary tubes.
