  • Piercing point optical fiber device for laser surgery procedures
    Patent number: 6011889
    Abstract: A device for use in laser surgical procedures for moving axially an optical fiber element that is connected at its proximal end to a source of laser energy. The distal end of the fiber elements with a cooperating piercing tip member has a tapered configuration so that it is capable of penetrating soft tissue of membrane such as the myocardium or epicardium of a human heart during the revascularization procedure. Various combinations of bundled optical fiber elements are disclosed which provide different tapered distal end designs that can be used in various surgical procedures.
    Type: Grant
    Filed: December 22, 1997
    Date of Patent: January 4, 2000
    Assignee: Eclipse Surgical Technologies, Inc.
    Inventors: Steven A. Daniel, Timothy C. Reynolds, Zachary E. Owyang
  • Optical fiber device and method for laser surgery procedures
    Patent number: 5703985
    Abstract: A device for use in laser surgical procedures for moving axially an optical fiber bundle that is connected at its proximal end to a source of laser energy. The distal end of the fiber bundle has a generally tapered configuration so that it is capable of penetrating soft tissue of membrane such as the myocardium or epicardium of a human heart during the surgical procedure. Various combinations of bundled optical fiber elements are disclosed which provide different tapered distal end configurations used for various surgical procedures.
