Abstract
The present invention relates generally to advantageous devices and methods for treating patients suffering from renal insufficiency and/or hepatic insufficiency. More particularly, the invention relates in certain aspects to devices and methods for performing continuous flow-through peritoneal dialysis (CFPD). In other aspects of the invention, peritoneal dialysis systems are provided which utilizes a bioreactor to regenerate peritoneal fluid for re-infusion into a peritoneal cavity. The invention, therefore, provides advantageous systems for passing fluid through a patient's peritoneal cavity at a relatively high flow rate, while maintaining in the peritoneal cavity an optimal dialysate pressure, to thereby alter the contents of the patient's blood by diffusion of molecules through the peritoneal membrane.
