Patent number: 9901753Abstract: A medical imaging and therapy device is provided that may include any of a number of features. One feature of the device is that it can deliver Lithotripsy therapy to a patient, so as to fractionate urinary stones. Another feature of the device is that it can deliver Histotripsy therapy to a patient, so as to erode urinary stones. In some embodiments, the medical imaging and therapy device is configured to target and track urinary stones in the patient during therapy. Methods associated with use of the medical imaging and therapy device are also covered.Type: GrantFiled: August 26, 2010Date of Patent: February 27, 2018Assignees: THE REGENTS OF THE UNIVERSITY OF MICHIGAN, HISTOSONICS, INC.Inventors: Charles A. Cain, Timothy L. Hall, William W. Roberts, Zhen Xu, J. Brian Fowlkes, Thomas W. Davison

Patent number: 9526923Abstract: A medical imaging and therapy device is provided that may include any of a number of features. One feature of the device is that it can acoustically couple an ultrasound therapy transducer to a patient. In some embodiments, the medical imaging and therapy device is configured to conform to the anatomy of a patient's perineal area to acoustically couple an ultrasound therapy transducer to the patient for treatment of BPH. The medical imaging and therapy device can be used in therapeutic applications such as Histotripsy, Lithotripsy, and HIFU, for example. Methods associated with use of the medical imaging and therapy device are also covered.Type: GrantFiled: June 22, 2015Date of Patent: December 27, 2016Assignees: HISTOSONICS, INC., THE REGENTS OF THE UNIVERSITY OF MICHIGANInventors: Russell C. Jahnke, James A. Bertolina, William W. Roberts, Charles A. Cain, Dejan Teofilovic, Thomas W. Davison

Patent number: 7850695Abstract: A method of fixing first and second vertebrae of a patient together at a surgical site includes inserting a first cannula into the body of the patient. A fusion device is moved through the cannula and inserted between the first and second vertebrae. A first fastener is moved through the cannula and secured to the first vertebra. A second fastener is moved through the cannula and secured to the second vertebra. A first fixation element is moved through the cannula. The first fixation element is fixed to the first and second fasteners. The fusion device has first and second ends, upper and lower surfaces for engaging the first and second vertebrae, and first and second side surfaces extending between the upper and lower surfaces. Each of the first and second side surfaces extend along an arc from the first end of the fusion device to the second end.Type: GrantFiled: August 12, 2004Date of Patent: December 14, 2010Assignee: Zimmer Spine, Inc.Inventors: James J.
