Patent number: 7967763Abstract: An apparatus and method for treating subcutaneous tissues using acoustic waves in the range of low acoustic pressure ultrasound waves is disclosed. The method includes injections of enhancing agents, wherein disruption of subcutaneous tissues and subcutaneous cavitational bioeffects are produced by ultrasound waves having a power that will not produce tissue cavitation in the absence of the enhancing agents. The apparatus and method of use is useful for treatment of subcutaneous abnormalities including cellulite, lipomas, and tumors.Type: GrantFiled: December 2, 2005Date of Patent: June 28, 2011Assignee: Cabochon Aesthetics, Inc.Inventors: Mark E. Deem, Hanson S. Gifford, III, Douglas Sutton

Patent number: 7870505Abstract: A graphical user interface for use in phacoemulsification surgical systems that allows a user to select different pulse modes by touching portions of the display screen. The user interface includes first and second display elements. One display element includes a representation of the on-time of the pulses, and the other display element includes a representation of the off-time. The representations show how the on-time and off-time change relative to a position of a controller, such as a foot pedal. The representation show a constant time, or that a time increases or decreases as the foot pedal is pressed. To select a pulse mode, a user can scroll through different pulse representations by touching the screen at the display elements. The selected pulse mode can be continuous, pulse, burst, or a combination or derivation thereof.Type: GrantFiled: April 11, 2006Date of Patent: January 11, 2011Assignee: Alcon, Inc.Inventors: Mikhail Boukhny, David A.

Patent number: 7806892Abstract: An ultrasound medical treatment system includes an end effector insertable into a patient. The end effector includes a tissue-retaining device. The tissue-retaining device includes a first tissue-retaining member having an ultrasound medical-treatment transducer and includes a second tissue-retaining member. The first and second tissue-retaining members are operatively connected together to retain patient tissue between the first and second tissue-retaining members and to release patient tissue so retained. In one example, the second tissue-retaining member has an ultrasound reflector. In the same or a different example, the ultrasound medical-treatment transducer is an ultrasound imaging and medical-treatment transducer.Type: GrantFiled: May 22, 2002Date of Patent: October 5, 2010Assignee: Ethicon Endo-Surgery, Inc.Inventors: Inder Raj S. Makin, Robert Dunki-Jacobs, Richard C. Pellegrino, Michael H. Slayton

Patent number: 7780624Abstract: Disclosed herein is an apparatus for removing fine tumor cells, which remain around a treatment area of patient body, from which a tumor is eliminated, after surgery for removing the tumor has been conducted. The apparatus of the present invention includes a main body, which has a supply tube and a discharge tube that circulate liquid supplied from a storage tank, which is provided outside, and a therapeutic member, which is integrally coupled to an extension pipe that is coupled to the main body and surrounds the supply tube and the discharge tube. A cavity, which communicates with the supply tube and the discharge tube and is supplied with the liquid, is defined in the therapeutic member. The apparatus further includes a temperature sensing unit, which measures a temperature of a treatment area of a patient.Type: GrantFiled: April 23, 2007Date of Patent: August 24, 2010Assignee: National Cancer CenterInventors: Seung-Hoon Lee, Yung-Ho Jo, Heon Yoo, Sang-Hoon Shin, Heung-Ki Jeon

Patent number: 7766833Abstract: A system for imaging and providing therapy to one or more regions of interest is presented. The system includes an imaging and therapy catheter configured to image an anatomical region to facilitate assessing need for therapy in one or more regions within the anatomical region and delivering therapy to the one or more regions of interest within the anatomical region. The catheter includes a therapy device having a plurality of independently controllable therapy elements. The independence of the therapy elements is exploited when multiple regions are to receive therapy simultaneously or at a given catheter position within a subject.Type: GrantFiled: February 21, 2006Date of Patent: August 3, 2010Assignee: General Electric CompanyInventors: Warren Lee, Mirsaid Seyed-Bolorforosh, Douglas Glenn Wildes
