A portable platelet apheresis system can include: a whole blood inlet configured to receive whole blood; an anticoagulant source containing an anticoagulant; a mixer fluidly coupled with the whole blood inlet and anticoagulant source and configured to mix the whole blood and the anticoagulant; a whole blood sorter microfluidic network; a platelet poor outlet positioned to receive a platelet poor fraction; and a platelet concentrator outlet positioned to receive a concentrated platelet fraction. The whole blood sorter microfluidic network includes: a sorter constricted region having a first cross-sectional dimension; a sorter expansion region having a second cross-sectional dimension that is larger than the first cross-sectional dimension; at least one sorter side channel (platelet rich plasma channel) formed into a side of the sorter expansion region; and at least one sorter outlet (platelet poor plasma channel) that is downstream or medial from the at least one sorter side channel.

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 system for liquid component fractionation includes a first container, a second container, a tunnel connecting member and a stopcock valve. The stopcock valve is a three-way valve disposed at the tunnel connecting member and is rotatable to align one of three ports of the stopcock valve to a collection outlet member of the tunnel connecting member, so as to facilitate collection of a fractionated layer from a liquid after the system is centrifuged.

Compositions and methods for separating a sample of whole blood or bone marrow aspirate into a fraction rich in at least one of platelets and pluripotent cells are provided. A sample of whole blood can be centrifuged in a collection tube comprising a separator substance formulated to settle between the PRP fraction and the at least one other fraction. Preferably, centrifugation is completed without substantial activation of platelets. Optionally, the separator substance could be hardened to form a solid barrier that allows removal of all or substantially all of the platelets in the PRP fraction without remixing of the PRP fraction with the at least one other fraction. Transfer devices and methods are also provided in which a sterile sample can be transferred from a separation/preparation container (e.g., vacutainer) to a consumer or other container (e.g., dropper) while maintaining sterility of the sample.

Embodiments of the invention include instruments and methods useful in preparing and delivering graft material to a surgical site. Some embodiments may particularly be directed to forming a graft from a blood clot and accurately and effectively handling and delivering the graft to a surgical site. Graft material may include blood components such as clotted fibrin derived from a patient's or a donor's blood.

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.

A method (and a system for implementing such method) for creating a plurality of fluid products each having a minimum content of a fluid component includes providing a plurality of intermediate fluid volumes each having a known content of a fluid component. The intermediate fluid volumes are grouped by fluid component content, followed by a determination of whether two of the intermediate fluid volumes may be pooled to achieve the minimum content for a final fluid product. The method proceeds with creating combinations of three and then more intermediate fluid volumes achieving the minimum content for a final fluid product, followed by creating combinations of intermediate fluid volumes exceeding the minimum content. Each intermediate fluid volume is assigned to only one of the combinations, with the intermediate fluid volumes being assigned to the combinations so as to maximize the number of combinations and, thus, the number of final fluid products.

A blood component sampling cassette which can be more efficiently manufactured at lower cost as compared to a typical cassette, a blood sampling circuit set, and a blood component sampling system. A blood component sampling cassette (22) includes a cassette main body (23) made of a soft material to which heat sterilization is applicable. The cassette main body (23) is provided with a retransfusion line (44). The retransfusion line (44) is provided with a reservoir (47) configured to temporarily store a blood component to be returned to a blood donor. The reservoir (47) is pressed by a retransfusion pump (49) to discharge the blood component from the reservoir (47).

Methods and kits for treating a cardiac arrhythmia using a platelet rich plasma (PRP) composition are provided. Any type of arrhythmia may be treated using the PRP composition. The PRP composition may comprise PRP developed using blood collected from a patient suffering the cardiac arrhythmia. The PRP composition may be buffered to a physiological pH and may include one or more anti-arrhythmic agents, anti-coagulants, or other drugs. The PRP composition may be delivered using a nebulizer, minimally invasively, or surgically.

The invention relates to a system, comprising: a) a sample processing unit, comprising an input port and an output port coupled to a rotating container having at least one sample chamber, the sample processing unit configured provide a first processing step to a sample or to rotate the container so as to apply a centrifugal force to a sample deposited in the chamber and separate at least a first component and a second component of the deposited sample; and b) a sample separation unit coupled to the output port of the sample processing unit, the cell separation unit comprising separation column holder (42), a pump (64) and a plurality of valves (1-11) configured to at least partially control fluid flow through a fluid circuitry and a separation column (40) positioned in the holder, the separation column configured to separate labeled and unlabeled components of sample flowed through the column.
