Systems and methods for providing multiple pass continuous flow dialysis therapy are provided. The present invention includes a fluid circuit connected to a patient via a catheter thereby defining a fluid loop along which a therapy fluid including a dialysate can be continuously circulated into, through and out of a peritoneal cavity of a patient to remove a therapeutically effective amount of excess water and solutes including uremic toxins. The feed rate and discharge rate of therapy fluid into the fluid loop can be controllably regulated in proportion to the circulation rate of fluid in the fluid loop such that the therapy fluid can pass a multiple number of times along the fluid loop prior to discharge.

A system and method for automatically adjusting a Continuous Cycling Peritoneal Dialysis (“CCPD”) therapy to minimize the potential for excess intra-peritoneal volume. The adjustments are made at the end of the drain, just prior to the next fill. The adjustments short the next fill, if necessary, to limit the intra-peritoneal volume, add a cycle, if necessary, to use all of the available dialysis solution and will average the remaining dwell time to maximize the therapeutic benefit of the therapy in the allotted time. In another embodiment, a tidal therapy using trended patient UF data is provided.

Apparatuses, devices, systems and methods for detecting access disconnection are provided. The present invention includes electrical contacts in fluid and electrical communication with a fluid passing between a patient and a medical system during therapy. In this regard, the present invention can use a direct-contact measurement to detect access disconnection, such as dislodgment of an access device from the patient through which fluid can flow during therapy including, for example, medication delivery, dialysis therapy and the like.

The invention relates to nutritional compositions and methods of using these compositions for the treatment of renal disease. More particularly, the invention discloses compositions of vitamins, minerals, amino acids, and/or proteins in amounts that can be used to supplement the nutritional deficiencies observed in patients afflicted with renal disease, renal insufficiency, or end-stage renal disease. The compositions of the invention can also be used as nutritional supplements for patients undergoing dialysis therapy or for patients on a restricted diet. In addition, the compositions can be used in combination or alone as a method of treating or managing a subject in the various stages of chronic renal disease, or throughout disease progression.

Dialysis systems and methods are described which can include a number of features. The dialysis systems described can be to provide dialysis therapy to a patient in the comfort of their own home. The dialysis system can be configured to prepare purified water from a tap water source in real-time that is used for creating a dialysate solution. The dialysis systems described also include features that make it easy for a patient to self-administer therapy. For example, the dialysis systems include disposable cartridge and patient tubing sets that are easily installed on the dialysis system and automatically align the tubing set, sensors, venous drip chamber, and other features with the corresponding components on the dialysis system. Methods of use are also provided, including automated priming sequences, blood return sequences, and dynamic balancing methods for controlling a rate of fluid transfer during different types of dialysis, including hemodialysis, ultrafiltration, and hemodiafiltration.

A dialyzer module utilizing a nano-porous ceramic membrane for enhanced hemodialysis performance, and a method for manufacturing the same, are provided. The dialyzer module may be utilized in an extracorporeal blood circuit together with pumps, monitors, and/or other components used for dialysis therapy. The one or more nano-porous ceramic tubes that serve as the hemodialysis membrane may comprise aluminum oxide (alumina) or titanium oxide (titania) tubes manufactured by the anodization of aluminum (Al) or titanium (Ti) tubes in an appropriate acid solution. The nano-porous ceramic tubes may be produced with a nano-porous wall structure having an average pore diameter of approximately five to ten nanometers (run). The nano-porous ceramic tubes exhibit a uniform pore size, uniform pore distribution, high porosity, and high hydraulic conductivity, enabling the removal of more middle and large molecular weight solutes to achieve a performance more comparable to that of an actual kidney while, at the same time, reducing the undesirable loss of important macromolecules such as albumin.

Apparatuses and methods for maintaining sterile connections during, for example, dialysis therapy. The present invention provides a container for a medical device and a lid therefore. The lid and the container are configured for an easy snap release using a cam-follower system. The invention also provides a method for using an assembly of the container, lid and a medical device within the container to maintain sterile connections.

The present invention relates to oral compositions which are useful for nutrient supplementation. The dietary supplements and pharmaceutical products and methods of the present invention are particularly useful in the treatment of patients in various stages of chronic kidney disease and supplementing levels of physiological anti-oxidants, vitamins, and minerals in subjects requiring dialysis therapy.

A new method is described to produce large volumes of low cost sterile, Water-for-Injection (WFI) grade water on-line, on-demand from potable water in order to meet the needs of dialysis therapies and other biological applications for sterile, injectable grade water. The source water is processed by a combination of membrane and column chromatographic methods including reverse osmosis, chemical sterilization, reduction of iodine sterilant to iodide, deionization, endotoxin-specific adsorption and polishing filtration in order to reduce contaminant levels below those specified by the US Pharmacopoeia.

The invention relates to systems and methods for adjusting one or more dialysis parameters for delivering a peritoneal dialysis cycle to a patient based on patient or system parameters. The systems and methods include various sensors, flow paths, and processors to adjust the dialysis parameters used to deliver peritoneal dialysis therapy, for a specific peritoneal dialysis cycle. For example, a first peritoneal dialysis cycle can provide data on patient or system parameters that can be used to adjust the dialysis parameters used to deliver a subsequent peritoneal dialysis cycle. One or more peritoneal dialysis cycles are contained in a particular peritoneal dialysis therapy session. Patient parameters can include patient blood pressure; volume of fluid removed; patient goal; blood solute level; effluent solute level; effluent temperature; effluent color or clarity; patient posture; tidal volume remaining in patient; and intraperitoneal pressure.

A weight detection device is disclosed for determining a patient's weight, for dialysis treatment, that includes patient scales arranged to carry out a weighing procedure to detect the actual weight of a patient, preferably a network connection arranged to connect a component of the weight detection device, generating information and/or data related to the determining of the patient's weight and/or to the weighing procedure, to a data network, an output device arranged to output the actual weight of the patient, and an image information recording device that includes a field of view directed to the patient scales for the visual detection of weighing procedures arranged to record the course of a weighing procedure such that a cause of a change in the actual weight occurring in the course of dialysis therapy can be determined from a recording of the weighing procedure.
