Patent number: 9399226Abstract: 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.Type: GrantFiled: January 21, 2014Date of Patent: July 26, 2016Assignee: HARVEST TECHNOLOGIES CORPORATIONInventors: James R. Ellsworth, Paul McGovern, Mark L. Kibbe

Patent number: 9162232Abstract: 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.Type: GrantFiled: January 3, 2013Date of Patent: October 20, 2015Assignee: HARVEST TECHNOLOGIES CORPORATIONInventor: James R. Ellsworth

Publication number: 20140274650Abstract: 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.Type: ApplicationFiled: August 16, 2012Publication date: September 18, 2014Applicant: HARVEST TECHNOLOGIES CORPORATIONInventor: James R. Ellsworth

Patent number: 8348887Abstract: A container (2) receives anhydrous material to be hydrated and hydrating fluids. The hydrating fluids are introduced into the container through a fluid port (8) by one or more containers having hydrating fluid. The hydrating fluids may be a mixture of fluids provided in any desired proportion. The hydrated material is then ejected from the container.Type: GrantFiled: December 23, 2005Date of Patent: January 8, 2013Assignee: Harvest Technologies CorporationInventors: P.

Patent number: 8152708Abstract: A centrifuge has a rotor for receiving a disposable processing unit. The centrifuge is configured such that the motor is attached to an enclosure and the enclosure is supported on a base. The connection between the base and the enclosure is a vibration isolator, and the isolator is positioned such that its effective line of action aligns with the effective plane of rotation of the rotor. In accordance with another feature of the invention, the processing units are held in a decanting position by a decant ring that moves vertically but does not rotate. The ring engages the top of the processing unit during decant and the abrasion is minimal.Type: GrantFiled: April 19, 2010Date of Patent: April 10, 2012Assignee: Harvest Technologies CorporationInventors: James R. Ellsworth, Paul McGovern
