Patent number: 10064644Abstract: The present disclosure relates generally to the field of tissue removal and more particularly to methods and devices for use in medical applications involving selective tissue removal. One exemplary method includes the steps of providing a tissue cutting instrument capable of distinguishing between target tissue to be removed and non-target tissue, urging the instrument against the target tissue and the non-target tissue, and allowing the instrument to cut the target tissue while automatically avoiding cutting of non-target tissue. Various tools for carrying out this method are also described.Type: GrantFiled: August 5, 2014Date of Patent: September 4, 2018Assignee: Microfabrica Inc.Inventors: Gregory P. Schmitz, Eric C.

Publication number: 20180230614Abstract: A counterfeiting deterrent device according to one implementation of the disclosure includes a plurality of layers formed by an additive process. Each of the layers may have a thickness of less than 100 microns. At least one of the layers has a series of indentations formed in an outer edge of the layer such that the indentations can be observed to verify that the device originated from a predetermined source. According to another implementation, a counterfeiting deterrent device includes at least one raised layer having outer edges in the shape of a logo. A light source is configured and arranged to shine a light through a slit in a substrate layer of the device and past an intermediate layer to light up the outer edge of the raised layer.

Patent number: 9671429Abstract: Some embodiments of the invention are directed to electrochemical fabrication methods for forming structures or devices (e.g. microprobes for use in die level testing of semiconductor devices) from a core material and a shell or coating material that (1) partially coats the surface of the structure, (2) completely coats the surface of the structure, and/or (3) completely coats the surface of structural material of each layer from which the structure is formed including interlayer regions. These embodiments incorporate both the core material and the shell material into the structure as each layer is formed along with a sacrificial material that is removed after formation of all layers of the structure. In some embodiments the core material may be a material that would be removed with sacrificial material if it were accessible by an etchant during removal of the sacrificial material.Type: GrantFiled: September 4, 2013Date of Patent: June 6, 2017Assignee: University of Southern CaliforniaInventors: Ming Ting Wu, Rulon J.
