Abstract
Systems and methods are provided for collecting a platelet product from a fluid including platelets and plasma. Platelet-rich plasma is separated from at least a portion of another constituent of the fluid and then may be further separated into concentrated platelets and platelet-poor plasma, with the concentrated platelets being resuspended. Separated platelets (in the form of platelet-rich plasma or resuspended platelets) are conveyed through a size exclusion filter and into a platelet storage container. The size exclusion filter is configured to remove platelet clumps and/or particles larger than a platelet from the separated platelets. Subsequently, an additive is conveyed through the size exclusion filter and into the platelet storage container. Conveying additive through the size exclusion filter improves platelet recovery in the platelet product by displacement of separated platelets with the additive and may also break up any platelet clumps that are present in the size exclusion filter.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
