  • Apparatus and method for closing a septal defect
    Patent number: 6312446
    Abstract: A catheter delivered device to close a septal defect, the device comprising a cylindrical shaft of metal or polymeric material with concentric parallel cuts through the wall of the device which create flattened support struts. The center of the support struts move radially away from the axis in a hinge like fashion in response to the movement of the device's proximal and distal ends toward the center of the device. This movement is reversibly effected through mechanical means. The device can be coated with growth factors, mitogenic factors or other determinants which can improve tissue growth such that tissue ingrowth can occur over a period of time. The catheter itself may be an ultrasonic imaging catheter.
    Type: Grant
    Filed: September 12, 2000
    Date of Patent: November 6, 2001
    Assignee: SciMed Life Systems, Inc.
    Inventors: Joseph Huebsch, Paul J. Buscemi, Thomas J. Holman, Danney Langanki
