  • Patent number: 6464707
    Abstract: A method and device for suturing tissue, in which the device includes a tube of a size to be inserted into a surgical site, such as into an artery or heart valve annulus of a patient. The tube includes a suction opening laterally circumscribing at least a portion of the tube to allow fluid communication between the tissue of the patient at the surgical site and the bore of the tube. Also within the tube is a carriage for detachably holding at least one needle, in which the carriage is slidably movable within the bore near the suction opening of the tube. When the tube is properly positioned, a vacuum source is placed in fluid communication with the bore of the tube so that the tissue is drawn into the suction opening of the tube. The carriage is then slid within the bore so that the needles detachably held thereby traverse the tissue, thus quickly and efficiently placing sutures in the tissue at the surgical site.
