The invention relates to a system for treating a biological fluid such as blood or a blood component by selective removal of a target substance, comprising a treatment bag (2) provided with at least one inlet orifice (3) and at least one outlet orifice (4), said treatment bag containing a set of particles (5) having an affinity for the target substance, said set comprising small particles having a size of less than 15 μm, said system further comprising a barrier means (6) composed of at least one porous membrane made of a hydrophilic material, the pores of said membrane being calibrated to a size suitable for preventing the passage of said small particles, namely less than 3 μm.

Flexible housing filters for filtration of fluids and methods of making such filters are disclosed. The filters may include one or more peripheral seals in the flexible housing.

A sterile solution product bag includes sterilization grade filter integrated directly into the product bag such that microbial and particulate matter filtration can be performed using the filter directly at the point of fill. The filter can include a hollow fiber filter membrane contained in a stem connected to a bladder of the product bag.

The present invention refers to a system and method for opening a concentrate container without the need for a human to directly handle the concentrate container and connecting the concentrate container to a blood treatment device. Aspects of the invention are directed to a container for concentrate and a blood treatment device.

A blood filter device having an iron-chelating molecule, a haem-binding molecule and a haemoglobin-binding molecule bound to a support. Use of the device in a vessel containing blood, for example a blood bag or a flow line, removes haemolysis-derived components from the blood.

The disclosure provides for a container system and method for the cryopreservation and resuspension of a body fluid. The container system may include a cryopreservation container comprising the body fluid in a cryopreservation liquid, a resuspension container comprising a resuspension solution, a connection tube sterilely connecting the cryopreservation container and the resuspension container, and at least one shut-off element actively associated with the connection tube.

A process for preparing blood components from blood, by means of a biomedical device (16), comprising the steps of: subjecting an isolated blood sample (1) to a first centrifugation at a speed of 250 rpm for a time of 10 minutes, and to a second centrifugation at a speed of 2000 rpm for a time of 15 minutes.

The invention relates to a filtration unit for the leucocytapheresis of the blood or of a blood product. The filtration unit has an external pouch with at least one inlet orifice and with at least one outlet orifice. the external pouch contains a porous element interposed between the orifices. he porous element has at least one leucocytapheresis medium that works by adsorbing and/or by filtering out the leucocytes, and at least one nonwoven layer provided with bumps, each of the bumps having a perforation passing through it in the heightwise direction.

Efficient methods for capture and removal of fibrinogen from blood plasma fractions, especially cryoprecipitate, and Fraction II+III providing high yields of blood coagulation Factor VIII are disclosed. According to this disclosure, there is provided a method of separating plasma cryoprecipitate or Fraction II+III comprising a blood coagulation factor and fibrinogen into a first fraction comprising the blood coagulation factor and a second fraction containing the fibrinogen, the method comprising: (a) contacting he plasma cryoprecipitate with solid SiO.sub.2 or Al(OH).sub.3, thereby adsorbing the fibrinogen onto the solid SiO.sub.2 or Al(OH).sub.3; and (b) separating the fibrinogen adsorbed onto the solid SiO.sub.2 or Al(OH).sub.3 from the blood factor, thereby forming the first fraction and the second fraction.
