Problems solved by technology

Advantageously, such a system is also sufficiently safe that the patient can continue to use it and carry on with normal activities without concern; that is, the system does not perform extracorporeal filtration of blood (such as hemodialysis), since the blood circulatory system may be prone to failure or loss of connection, resulting in rapid blood loss and death

Embodiment Construction

[0035] The present invention relates generally to an artificial kidney dialysis system comprising a wearable peritoneal dialysis device or system for removing uremic metabolic waste products from a patient suffering from a disorder associated with accumulation of uremic toxins, such as chronic renal failure, and from An implantable fluid removal device that removes fluid from the patient's blood and preferably delivers the fluid to the bladder so that the fluid can be removed by natural urination. The system can be used to treat kidney disease-like disorders, for example, including early kidney disease, renal dysfunction, or kidney failure (eg, advanced kidney disease). As used herein, the term "uremic metabolic waste" refers to compounds produced by the body as waste products (eg, nitrogenous compounds) and includes substances such as urea, uric acid, creatinine, and β2 microglobulin and others (see Vanholder Compounds of R et al. Kidney International 63:1934-1943, 2003). Re...

Abstract

The present disclosure relates to a wearable dialysis system and method for removing uremic waste metabolites and fluid from a patient suffering from renal disease. Uremic waste metabolites can be removed by a wearable peritoneal dialysis device (10) that regenerates the peritoneal dialysis solution without removing positively charged, essential ions from the solution and, consequently, the patient. Fluids can be removed. from the blood of the patient by an implantable fluid removing device (100). Fluids are delivered to the bladder and preferably removed from the body of the patient through urination. The wearable dialysis system may be operated continuously or; semi-continuously and be comfortably adapted to the body of the patient while allowing the patient to perform normal activities.

Description

[0001] related application [0002] This application claims priority to U.S. Application No. 11 / 895,075, filed August 23, 2007, which is a continuation-in-part of International Application No. PCT / US2007 / 005779, filed March 8, 2007, This international application claims priority to US Application No. 11 / 371,216, filed March 8, 2006. The entire content and teachings of the aforementioned applications are incorporated herein by reference. Background technique [0003] Kidney dysfunction or failure, especially in advanced kidney disease, causes the body to lose its ability to shed water and minerals, excrete harmful metabolites, maintain acid-base balance, and control electrolyte and mineral concentrations within physiological ranges. Toxic uremic metabolic wastes include urea, creatinine, and uric acid that accumulate in body tissues, which can kill patients if they do not replace the filtering function of the kidneys. [0004] Dialysis is often used to replace kidney function...
