A method that regulates supply of substituate in an extracorporeal blood treatment with an extracorporeal blood treatment apparatus comprising a dialyzer divided by a semipermeable membrane into a blood chamber and a dialyzing fluid chamber and a device for supplying substituate. An extracorporeal blood treatment apparatus that includes a device for regulating supply of substituate. Regulation of supply of substituate in the extracorporeal blood treatment takes place as a function of the rheological loading of the dialyzer. To regulate supply of substituate during extracorporeal blood treatment, rheological loading of the dialyzer is determined from transmembrane pressure on the dialyzer and flow resistance of the dialyzer and substituate rate is increased or reduced according to the loading. The selection of dialyzer parameters or blood parameters is therefore no longer necessary and the distinction between pre-dilution and post-dilution is also made obsolete.

The present invention refers to a system and method for connecting a concentrate container with a blood treatment device with improved hygiene. Furthermore, the invention refers to a container and blood treatment device to be used in a method according to the present invention.

A device for extracting arterial and pulmonary embolisms. Blood containing unwanted material is suctioned out of a patient, is filtered in the reservoir, and is returned to the patient. The device includes a suction catheter and a return catheter attached to a filter reservoir. The device may also include a daughter catheter to reach smaller spaces and a fishing catheter to catch and reel the unwanted material toward the suction catheter. The reservoir is a two-stage filter that filters out any unwanted material from the blood and de-airs the blood prior to returning the blood back to the patient. The suction system can be manual or controlled by a console integrated with computer readable instructions and algorithms to safely return the filtered and de-aired blood.

A system and method for connecting a concentrate container with a blood treatment device with improved hygiene. Furthermore, a container and blood treatment device useful with the system and method are also provided.

A crossflow filter includes a rigid cylindrical inner wall and a rigid cylindrical outer wall inner with an inelastic filter membrane positioned therebetween defining a retentate channel inside the filter membrane and a permeate channel outside the filter membrane. Further, the filter includes transition channels shaped and connected to the inner and outer walls to deliver a flow of fluid from an inlet port to the retentate channel and to capture flow flowing longitudinally along the cylindrical inner and outer walls from both the retentate and permeate channels to respective outlet ports.

A mesh-type hemofiltration filter formed of resin fibers, characterized in that: the mesh number is 300 mesh or more; the aperture ratio is 30-50% inclusive; the fiber diameter of the fibers is 10-40 m inclusive; and the weave pattern is a plain weave or a triple twill diagonal weave. The hemofiltration filter is capable of removing foreign substances such as blood clots and proteins while maintaining a sufficient blood filtration flow rate.
