  • Ultrasonic transducer array and method of manufacturing the same
    Patent number: 6776763
    Abstract: In a method of manufacturing an ultrasonic transducer array a plurality of discrete transducer elements are formed on an initially flat flexible substrate together with electrically conductive tracks, through which the transducer elements will be energised in use, the flexible substrate with the discrete transducer elements and conductive tracks mounted thereon then being formed into a cylinder and mounted on the end of a catheter tube, the substrate being radially outwardly of the transducer elements so that it is in a position to act also as an acoustic matching layer between the material of the transducer elements and the human tissues or blood when in use.
    Type: Grant
    Filed: January 31, 2002
    Date of Patent: August 17, 2004
    Assignee: Volcano Therapeutic, Inc.
    Inventors: Elvin Leonard Nix, George Woodrow Keilman, Robert Julian Dickinson
