ABSTRACT: The objective of this proposal is to build a foundation for the modeling of polymer powders for use in laser sintering (LS). These models will attempt to provide a basis for characterizing new LS material candidates, establishing a fundamental understanding of material behavior so that existing molding grade polymers can be adapted for use in LS, and qualifying LS feedstock for use in production. BENEFIT: Increased adaptation of LS grade polymers which should lead to decreased raw material costs, increased supply chain security, and broader mechanical properties. In addition, will potentially create a tool to help manage powder feedstock through recycling and mapping process parameters to measured powder quality.


Platelet rich plasma and/or platelet concentrate is prepared by placing whole blood in a first chamber of a sterile processing disposable having two chambers. The processing disposable is subjected to a first centrifugation to separate red blood cells, and the resulting platelet rich plasma supernatant is decanted to the second chamber. The processing disposable is subjected to a second centrifugation to concentrate platelets. A volume of the platelet poor plasma supernatant in the second chamber is removed, and the platelets are re-suspended in the remaining plasma. The second chamber may contain anticoagulant to preclude aggregation of the platelets.

Adipose is obtained from aspirated adipose by centrifugal separation of adipose from tumescent fluids and oils released from damaged adipose cells. Aspirated adipose is placed in a container having therein a disk that floats on adipose and takes up the released oils whereby they are unlikely to remix with the adipose during handling after centrifugation. The disk also adheres to the adipose by entraining part of the adipose layer.

Devices for extracting bone marrow from a bone of a patient are disclosed. The device includes a housing defined in part by a cannula and a hollow needle disposed within the cannula. The hollow needle is movable axially relative to the cannula and extendable therefrom. The hollow needle is configured to aspirate bone marrow within a bone. A depth adjustment mechanism coupled to the hollow needle and the cannula is used to adjust the depth of the hollow needle relative to the cannula to control the distance of the needle within the bone. The device is attachable to an extraction device to extract bone marrow from the patient through the hollow needle. Methods of using these devices and methods of extracting bone marrow are also included.

Methods and systems for collecting and processing bone marrow in a closed system are provided. The systems and methods include the use of a bone marrow aspiration needle and guide configured to puncture cortical bone. Tube assembly is in fluid flow communication with the bone marrow aspiration needle. A first syringe is in fluid flow communication with the tube assembly and the bone aspiration. A bone marrow aspirate collection container in fluid flow communication with the first syringe and the tube assembly. A second syringe is connected to the collection container, a bone marrow aspirate filter in fluid flow communication with the tube assembly to filter bone marrow aspirate from the first syringe into the collection container. At least one flow controller is configured to direct the flow of bone marrow aspirate between the aspiration needle, the first syringe and the collection container.

A floating separating element for use in centrifugal separation of components of a physiological fluid comprises a positioning part and a separating part, where the positioning part is designed to automatically assume a position in a supernatant and a separating part is positioned at a desired location with respect to the interface between the supernatant and heavier components. In preferred embodiments the physiological fluids are blood or bone marrow aspirate, and the heavier components comprise red blood cells. The positioning part comprises the majority of the mass of the separating element and is thin so that differences in the position of the separating element with respect to the interface are small compared to differences in the densities of the separated components, particularly the component comprising red blood cells. A method allows red blood cells to move the separating element during decanting to ensure complete decant of the supernatant.

A floating element for separating components of a physiological fluid comprises two parts that are relatively movable. The two parts define a prescribed volume between them when at their maximum separation, and one of the parts may be moved toward the other to express the fluid contained in the volume between the parts. The parts are made of materials having densities so that they assume a desired position in the fluid to allow selected components to be easily obtained and expressed.
