Patent number: 10293188Abstract: A method and apparatus is disclosed for determining the success of a proposed HIFU Treatment, of an ongoing HIFU Treatment, and/or of a completed HIFU Treatment. An energy density of a given HIFU Treatment may be used as a comparison factor between the given HIFU Treatment and other HIFU Treatments and as a predictor of the success of the given HIFU Treatment. One exemplary energy density is the amount of energy deposited in the treatment region divided by the volume of the treatment region. Another exemplary energy density is the amount of energy deposited in the treatment region divided by the pre-treatment mass of the treatment region. A method and apparatus is disclosed to detect the presence of focal hyperechoic features and non-focal hyperechoic features. A method and apparatus is disclosed to detect the presence of an acoustic obstruction.Type: GrantFiled: July 20, 2015Date of Patent: May 21, 2019Inventors: Russell J. Fedewa, Toyoaki Uchida, Narendra T. Sanghvi, Roy F. Carlson

Publication number: 20120150035Abstract: A HIFU System (100) is disclosed which may automatically generate a proposed treatment plan for treating a tissue treatment area (10) with HIFU Therapy. In one example, the proposed treatment plan includes a plurality of treatment sites selected based on a three-dimensional model generated from ultrasound data. In another example, the proposed treatment plan excludes portions of the tissue treatment area (10) corresponding to blood flow, such as the neuro-vascular bundles (20) when treating the prostate (11).Type: ApplicationFiled: February 15, 2012Publication date: June 14, 2012Applicant: FOCUS SURGERY INC.Inventors: Ralf Seip, Wo-Hsing Chen, Roy F.

Patent number: 5576490Abstract: A rotary element dynamic imbalance determining apparatus includes a spindle having a first end for removably supporting a rotary element the imbalance of which is to be determined, and a housing for rotatably mounting the spindle. An output signal related to imbalance in the supported rotary element is generated as the spindle rotates. A rotary fluid coupling comprises a chamber between the spindle and housing, a port in the housing for coupling the chamber to a source of compressed air and a one-way fluid seal for dividing the chamber into a first portion and a second portion. A passageway extends along the spindle from the second portion to the first end of the spindle to supply inflating air thereto.Type: GrantFiled: September 30, 1994Date of Patent: November 19, 1996Assignee: Illinois Tool Works, Inc.Inventors: Peter L.
