Publication number: 20150105750Abstract: The present disclosure relates to a vessel configured to apply pressure greater than ambient pressure and/or provide a reduced headspace to a sample, while subject to focused acoustic treatment. Such treatment may generally result in enhanced effects of sterilization and/or other processing than if the sample is otherwise treated under ambient conditions. The sample may be a medicament that is sterilized under pressure using focused acoustic energy, where the sterilized sample is subsequently delivered to a patient. A fluid delivery cartridge may include a vessel having a transfer end opposite a plunger end. The transfer end may include a sealed cover. A plunger may be movably disposed in the vessel to accommodate entry of a liquid via piercing of the sealed cover. Upon processing (e.g., sterilizing) of the sample with focused acoustic energy, the sample may be appropriately dispensed through the pierced sealed cover.Type: ApplicationFiled: October 15, 2014Publication date: April 16, 2015Applicant: Covaris, Inc.Inventors: James A.

Publication number: 20150079655Abstract: Methods and systems for treating material with focused acoustic energy and/or ultraviolet radiation are described. Sample material may be provided to a single batch vessel or may flow in a continuous or intermittent fashion into/out of a processing chamber within which the material is exposed to focused acoustic energy and/or ultraviolet radiation. Exposure to focused acoustics in a flow through environment may enhance the effects of the radiation on the sample material. Further, in flow-through or single batch arrangements, sample material may be retained exterior to or within a processing chamber by one or more retaining members (e.g., filter, valve, etc.) until a characteristic of the sample material reaches one or more particular criteria (e.g., physical, chemical, biological). Once the criteria of the sample material is attained (e.g., via further treatment), the material is then permitted to flow past the retaining member(s) and through the inlet or outlet of the chamber.Type: ApplicationFiled: September 17, 2013Publication date: March 19, 2015Applicant: Covaris, Inc.Inventors: James A. Laugharn, JR., Xiaoyin He, Srikanth Kakumanu

Publication number: 20150056715Abstract: Methods and systems for acoustically treating material using an acoustic energy system having a movable outer surface that contacts a sample holder. The outer surface may be cylindrical and rotate about a central axis, e.g., so that a sample holder may be driven to move by the outer surface. Acoustic energy may be emitted from within the outer surface to a treatment area outside of, and near, the outer surface. Thus, a sample holder in contact with the outer surface may have a sample exposed to acoustic energy while rotation of the outer surface may move the sample holder relative to treatment area. One or more additional rollers or other components may bias the sample holder into contact with the outer surface, to e.g., so the sample holder is squeezed between the outer surface and a roller or other biasing component.Type: ApplicationFiled: August 20, 2014Publication date: February 26, 2015Applicant: Covaris, Inc.Inventors: James A. Laugharn, JR., Xiaoyin He

Publication number: 20140363843Abstract: Systems and methods for processing tissue samples using acoustic energy. The tissue sample may be collected and placed on a substrate (e.g., microscope slide), or other sample holder. A transfer substrate may be positioned on the other side of the sample opposite the substrate. A microscope incorporated with the acoustic treatment system may be used to view, identify and select a portion of the sample to be transferred from the initial substrate to the transfer substrate. The selected portion of the sample is exposed to focused acoustic energy while disposed between the two substrates. The focused acoustic energy has characteristics (e.g., high frequency, small focal zone) that may be effective to transfer the selected portion of the sample from the initial substrate to the transfer substrate. Such transfer may occur with little to no damage to the sample, for example, at low temperature isothermal conditions and/or little to no cavitation of or around the sample.Type: ApplicationFiled: June 6, 2013Publication date: December 11, 2014Inventor: James A. Laugharn, JR.

Patent number: 8409801Abstract: A method and apparatus for exposing a sample, including a liquid and another material, to sonic energy to produce a desired result such as, suspending a material support in the liquid. The material support may be a bead or other particle with at least one surface feature to which the material may bind. Material in the liquid may attach to the material support, such as by specific or non-specific binding, entrapment or other, so as to facilitate separation of the material from the liquid. Separation of the material supports from the liquid and other unbound material may be done by allowing the material supports to settle out, e.g., under the force of gravity and/or as assisted by centrifugation, by applying a magnetic field in case the supports or material bound to the supports are movable by way of a magnetic field, or other techniques.Type: GrantFiled: February 2, 2010Date of Patent: April 2, 2013Assignee: Covaris, Inc.Inventor: James A.
