  • BALLOON CATHETER VISUALIZATION SYSTEMS, METHODS, AND DEVICES HAVING PLEDGETS
    Publication number: 20160213237
    Abstract: A balloon catheter visualization system for repairing a heart valve in a patent includes one or more elongate shafts, each shaft defining at least one lumen and comprising a distal end portion and a proximal end portion. The system also includes a transparent balloon member coupled to the one or more elongate shafts and is in fluid communication with at least one lumen of the one or more elongate shafts. The system also includes an imaging element disposed within the balloon member and coupled to a distal end portion of the one or more elongate shafts, a fastener releasably coupled to a distal end portion of the one or more elongate shafts, and a connector coupled to a distal end portion of the one or more elongate shafts. The connector is adapted to fasten the fastener to tissue.
