A method for platelet preservation comprising placing a composition comprising platelets in a gas mixture comprising xenon and oxygen under pressure of about 0-10 Bars at a first temperature of about 18° C.-37° C. for a first period of time, and then subsequently cooling the composition to a second temperature of about 0,1° C.-6° C., and holding the composition under the pressure and in the second temperature for a second period of time.

A sample heating/cooling device (2) comprises a plurality of members (6) operable in use to heat and/or cool one or more samples (22). Each member (6) has a sample contact surface and is biased towards a resting position under the operation of a biasing means. The members (6) are movable independently of one another against said bias under the application of a force on the sample contact surface and so are able to conform to the shape of a sample placed on the members to provide a uniform heating/cooling profile. The members (6) may be mounted in a heating/cooling element (4) and adapted to conduct thermal energy between the sample (22) and the element (4). The device (2) is particularly suitable for thawing frozen sample bags having an irregular shape. A corresponding method is also described.

Provided is a method for producing platelets, in which damage to platelets is suppressed compared with a method in which platelets are separated using a filter from a megakaryocyte culture, and then the platelets are concentrated using a hollow fiber membrane and are further washed using the hollow fiber membrane, and purified platelets can be produced in a shorter period of time compared with the time that is taken to perform the above-described method so as to reduce damage to platelets. The method for producing purified platelets of the present invention includes a concentrating step of concentrating a megakaryocyte culture, and a centrifuging step of centrifuging platelets from an obtained concentrate.

Biological fluid processing cassettes with integrated filter structures are disclosed. A cassette body is formed of a generally rigid material, defining a plurality of internal fluid flow paths. The cassette body may be secured to a cassette cap to define a cavity, with a filter sealed within the cavity. Each of the cassette body and the cassette cap defines a port opening into the cavity, which allows fluid to flow from one of the internal fluid flow paths, into the cavity and through the filter, and then out of the cavity via the port of the cassette cap. Alternatively, the cassette body may define an external slot which receives at least a portion of a filter. Such a filter includes two ports, with one of the ports in fluid communication with a cassette port of the cassette body to allow fluid flow between the cassette body and the filter.

A cell processing system includes a processor connectable to a source container filled with a biological fluid, the processor including a separator configured to separate the biological fluid from the source container into at least two streams according to a process including at least one process parameter, and a controller coupled to the processor and an input. The controller is configured to receive the at least one process parameter, to evaluate the process using the at least one process parameter before performing the process, and to carry out one or more actions based on the evaluation, such as providing an output estimate to the operator, preventing the process from being performed according to a comparison between a calculated condition and a control, or providing an error indication to the operator according to the calculated condition and a measured in-process condition.

The invention concerns methods of treating blood, blood product, or physiologic fluid to provide at least one of (i) increasing shelf life of the blood, blood product or physiologic fluid, (ii) maintaining freshness of new blood, blood product or physiologic fluid, and (iii) removing undesirable molecules from the blood, blood product or physiologic fluid; said method comprising contacting said blood, blood product or physiologic fluid with a sorbent, said sorbent being primarily in a plurality of solid forms and comprising a cross-linked polymeric material having a plurality of at least one of (1) zwitterionic moieties and (2) oligo(ethylene glycol) moieties attached to the surface of said cross-linked polymeric material.

Described are embodiments that include methods and devices for separating components from multi-component fluids. Embodiments may involve use of separation vessels and movement of components into and out of separation vessels through ports. Embodiments may involve the separation of plasma from whole blood. Also described are embodiments that include methods and devices for positioning portions, e.g., loops, of disposables in medical devices. Embodiments may involve use of surfaces for automatically guiding loops to position them into a predetermined position.

The present disclosure relates to Oxygen Reduction Disposable kits (ORDKit), devices and methods for the improved preservation of whole blood and blood components. The improved devices and methods for the collection of blood and blood components provide for whole blood and blood components having reduced levels of oxygen. The devices and methods provide for the rapid preparation of deoxygenated blood and blood components for storage that improves the overall quality of the transfused blood and improves health outcomes in patients.

A system for storing a blood product includes an inner container configured to contain the blood product, wherein the inner container is permeable to a gas system, and an outer container including a first end, a second end opposite the first end, a cavity defined between the first and second ends, an inlet in fluid communication with the cavity, and a valve operable to control a flow of the gas system through the inlet. The inner container is insertable into the cavity through the first end, the first end is sealable to hermetically seal the inner container within the cavity, and the outer container is made of a material that is impermeable to the gas system.
