Patent number: 9372185Abstract: A MEMS-based system and a method are described for separating a target particle from the remainder of a fluid stream. The system makes use of a unique, microfabricated movable structure formed on a substrate, which moves in a rotary fashion about one or more fixed points, which are all located on one side of the axis of motion. The movable structure is actuated by a separate force-generating apparatus, which is entirely separate from the movable structure formed on its substrate. This allows the movable structure to be entirely submerged in the sample fluid.Type: GrantFiled: July 29, 2013Date of Patent: June 21, 2016Assignees: Owl Biomedical, Inc., Innovative Micro TechnologyInventors: John S Foster, Daryl W. Grummitt, Jaquelin K. Spong, Kimberley L. Turner, John C. Harley

Patent number: 8343791Abstract: A method for forming through features in a substrate uses a seed layer deposited over a first substrate, and a second substrate bonded to the seed layer. The features may be formed in the first substrate, by plating a conductive filler material onto the seed layer. The first substrate and the second substrate may then be bonded to a third substrate, and the second substrate is removed, leaving through features and first substrate adhered to the third substrate. The through features may provide at least one of electrical access and motion to a plurality of devices formed on the third substrate, or may impart movement to a moveable feature on the first substrate, wherein the third substrate supports the first substrate after removal of the second substrate.Type: GrantFiled: October 5, 2010Date of Patent: January 1, 2013Assignee: Innovative Micro TechnologyInventors: John S.

Publication number: 20120164718Abstract: A micromechanical particle sorting system uses a removable/disposable apparatus which may include a compressible device, a filter apparatus and a cell sorter chip assembly. The chip assembly may include a tubing strain relief manifold and a microfabricated cell sorting chip.

Patent number: 7229838Abstract: A micromechanical particle sorting chip uses an actuator divided into two parts to direct a component of interest into one of a plurality of possible exit paths, based on detection of a fluorescent signal emanating from the component of interest. The two-part actuator may include a force-generating portion and a microactuator portion. The microactuator portion may be disposable, whereas the force-generating portion may be reuseable. By bringing the force-generating portion into proximity to the microactuator portion, the microactuator is induced to move, thereby separating the component of interest from the rest of the fluid stream. The force-generating portion and the microactuator portion may be optimized and fabricated separately, thereby leading to faster, more reliable and less expensive particle sorting.Type: GrantFiled: October 28, 2005Date of Patent: June 12, 2007Assignee: Innovative Micro TechnologyInventors: John S. Foster, John C. Harley, Steven H. Hovey, Richard T. Martin, Hung D. Nguyen, Paul J. Rubel

Patent number: 7220594Abstract: A micromechanical particle sorting chip uses laser light directed through at least one of a reflective and refractive surface to come to a focus in an optically transparent layer. The laser light impinges on a particle of interest, causing it to fluoresce. Upon detecting the fluorescence, a micromemchanical actuator is activated, which directs the particle of interest into one of a plurality of possible exit paths.Type: GrantFiled: August 4, 2005Date of Patent: May 22, 2007Assignee: Innovative Micro TechnologyInventors: John S.
