摘要:
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.
摘要:
A balloon catheter suturing system (100) includes an elongate shaft (112) defining a lumen and having a distal end portion and a proximal end portion and a balloon (108) attached to the distal end portion of the shaft. The balloon includes a balloon wall; at least a first pledget (126) that is part of the balloon wall and adapted to tear away from the balloon wall; and at least one fastener adapted to fasten the first pledget to an anatomic structure when the balloon catheter suturing system is positioned within a patient.
