Patent number: 9693790Abstract: A surgical instrument for removing a gallbladder is provided. The surgical instrument includes a handle assembly, an elongated body portion extending distally from the handle assembly, and a capture portion operably mounted on a distal end of the elongated body portion. The capture portion defines a tissue receiving opening when in an open configuration and is configured for receipt through an incision when in the capture portion is in a closed configuration. The capture portion includes at least one sharpened member for cutting tissue received within the tissue receiving opening as the capture portion moves from the open configuration to the closed configuration. Also provided is a method of removing a gallbladder using a surgical instrument.Type: GrantFiled: August 1, 2013Date of Patent: July 4, 2017Assignees: Covidien LP, The Regents of the University of Michigan, University of MichiganInventors: Yuhao He, Scott LaTulip, Zongchang Liu, Yang Wei, Taiming Chu

Patent number: 9395453Abstract: A radiation sensor includes a scintillation layer configured to emit photons upon interaction with ionizing radiation and a photodetector including in order a first electrode, a photosensitive layer, and a photon-transmissive second electrode disposed in proximity to the scintillation layer. The photosensitive layer is configured to generate electron-hole pairs upon interaction with a part of the photons. The radiation sensor includes pixel circuitry electrically connected to the first electrode and configured to measure an imaging signal indicative of the electron-hole pairs generated in the photosensitive layer and a planarization layer disposed on the pixel circuitry between the first electrode and the pixel circuitry such that the first electrode is above a plane including the pixel circuitry. A surface of at least one of the first electrode and the second electrode at least partially overlaps the pixel circuitry and has a surface inflection above features of the pixel circuitry.Type: GrantFiled: April 16, 2015Date of Patent: July 19, 2016Assignee: The Regents of the University of Michigan, University of Michigan Office of Technology TransferInventor: Larry E. Antonuk
