Harvest Technologies | Date: 2011-11-23

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.

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.

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.
