A method and system for treating Alzheimer's disease wherein blood, spinal fluid or brain cavity fluid is circulated into and outside of the body by means of blood pumps or other external circulatory systems. While passing through the pumping system, the amyloid plaques and Tao tangles are filtered from the fluids and returned to the body lowering the protein levels, and in the process, reduce symptoms. In one embodiment a patient's blood is filtered using a pump to circulate the blood from the patient to the collection vessel where an electrical current will cause anything that has a positive charge to be attracted to a cathode plate suspended in the collection vessel for later disposal. In an alternate embodiment a patient's brain and/or spinal fluid a pump operates to circulate a flushing fluid. The pump will circulate the solution from the collection vessel to the patient.

A dialysis device (100) comprises: a dialyzer for exchange of substances between a blood flow and a dialysate flow in a dialysis area (106) of the dialyzer, wherein the dialyzer comprises a dialyzer membrane (110) for passing toxins in the blood flow to the dialysate flow through pores (112) of the dialyzer membrane (110); and a capacitively coupled generator (120) for generating electromagnetic fields in the dialysis area (106) for loosening electrostatic bonds between toxins and proteins in the blood flow, wherein the generator (120) is capacitively coupled to the blood flow and to the dialysate flow on opposite sides of the dialyzer membrane, and wherein the dialysate membrane (110) is formed of a material having lower conductance than blood and dialysate such that a large electromagnetic field strength is provided across the pores (112) of the dialyzer membrane (110).

Disclosed are: a system comprising a gas circulation device capable of circulating hyperthermic gas in the peritoneal cavity and a temperature control device; and a system comprising a drug spray device for effectively spraying a drug in the peritoneal cavity together with gas. The systems of the present invention are used as systems for hyperthermic intraperitoneal chemotherapy and can maximize the anticancer therapy effect by more effectively delivering a small amount of an anticancer drug to cancer cells while maintaining the temperature of gas in the peritoneal cavity at a predetermined temperature.

The present invention relates to a device and a method for FIG. 2 treating fat cells taken from a patient and intended for a transplant. More specifically, it relates to a device and a method by suctioning which makes it possible to separate the viable fat cells from the residues and elements which are not transplantable. The device is a device for treating adipose tissues (G) connected to a suctioning means (M), consisting of a sealed treatment chamber (A) comprising a means for connection (17) to said suctioning means (M), a means for inlet (13) of said adipose tissues before treatment, a filtration means (3) and at least one means for outlet (20) of said adipose tissues (G) after treatment, said filtration means (3) comprising a conically shaped external wall (3 1, 3) comprising a narrow base (55) attached to an impeller (25) and an internal sieving means (30) connected to the output means (20), said impeller (25) being subjected to the air pressure reduction created by the suctioning means (M) and constituting a rotary mechanical actuating means for actuating said filtration means (3).

An apparatus (1a) for extracorporeal blood treatment, comprising an infusion control arrangement (8) arranged for infusing a pre-dilution flow rate upstream a blood treatment unit (4) and a post-dilution flow rate downstream the blood treatment unit (4), an ultrafiltration, UF, arrangement (40) arranged for ultrafiltration of a liquid through a semipermeable membrane (7) of the blood treatment unit (4) and a control unit (31). The control unit (31) is configured to configure the infusion control arrangement (8) to obtain a plurality of different configurations of the pre-dilution flow rate and/or post-dilution flow rate. For each of the plurality of different configurations, the control unit (31) is configured to change an operating situation of the UF arrangement (40), to detect a plurality of ultrafiltration flow rate values through the membrane (7) as a function of TMP, on changing said operating situation, and to evaluate an optimal ultrafiltration flow rate value from a comparison of the detected ultrafiltration flow rates. The apparatus (1a) is also configured to estimate a clearance value for a certain solute at the optimal ultrafiltration flow rate value and to evaluate a preferred configuration of the pre-dilution flow rate and/or post-dilution flow rate from a comparison of the corresponding estimated clearance values.

The invention relates to a blood line (108) comprising an infusion site (145) intended to inject into the line a solution, comprising: a first main channel (200) having a first passage section, a second main channel (220) having a second passage section, means for the formation (210) of a turbulence area located downstream from the first main channel, located upstream from the second main channel, these formation means comprising a first fluid passage means (224) defining a reduction (225) in the passage section and whose smallest passage section is smaller than the first passage section and smaller than the second fluid passage section, a secondary channel (230) comprising an inlet (231) for letting in the solution and an outlet (232) in fluid communication with the first main channel or the means for the formation of a turbulence area or the second main channel.

The present invention provides for a removable second stage biocompatible substrate filter that includes biocompatible implant material configured to trap second stage operative particulate matter that may include at least one of bone fragments, plasma, stem cells, cellular matter, and growth factors captured from irrigation fluid. The second stage biocompatible substrate filter may be configured to combine with bone fragments captured from irrigation fluid by a first stage filter and may be configured to be operable with a reaming and collection device.

Dialysis is enhanced by using nanoclay sorbents to better absorb body wastes in a flow-through system. The nanoclay sorbents, using montmorillonite, bentonite, and other clays, absorb significantly more ammonium, phosphate, and creatinine, and the like, than conventional sorbents. The montmorillonite, the bentonite, and the other clays may be used in wearable systems, such as a wearable peritoneal dialysis system, in which a dialysis fluid is circulated through a filter with the nanoclay sorbents. Waste products are absorbed by the montmorillonite, the bentonite, and the other clays and the dialysis fluid is recycled to a patient's peritoneum. Using an ion-exchange capability of the montmorillonite, the bentonite, and the other clays, waste ions in the dialysis fluid are replaced with desirable ions, such as calcium, magnesium, and bicarbonate. The nanoclay sorbents are also useful for refreshing a dialysis fluid used in hemodialysis and thus reducing a quantity of the dialysis fluid needed for the hemodialysis.
