  • Patent number: 8313496
    Abstract: A system for endoscopic suturing is provided having an endoscope, such as a gastroscope, with a distal end locatable in the body of a patient and a flexible shaft extending to the distal end, a flexible accessory tube coupled to the endoscope to flex relative to the endoscope's shaft, and a tip coupled to the shaft of the endoscope having an opening through which one end of the accessory tube is received. Tissue suturing and suture securing instruments are provided each having a sufficiently flexible shaft locatable through the accessory tube.
    Type: Grant
    Filed: May 15, 2003
    Date of Patent: November 20, 2012

  • Publication number: 20100331623
    Abstract: A system for endoscopic suturing is provided having an endoscope, such as a gastroscope, with a distal end locatable in the body of a patient and a flexible shaft extending to the distal end, a flexible accessory tube coupled to the endoscope to be movable relative to the endoscope's shaft, and a tip coupled to the shaft of the endoscope having an opening through which one end of the accessory tube is received. A tissue suturing instrument is provided having a partially flexible shaft locatable through the accessory tube, and a tissue engaging end coupled to the shaft. The tissue engaging end has a vacuum sleeve enabling suction to be selectably applied at the tissue engaging end to capture tissue through an opening in the vacuum sleeve. Two needles are provided which extend through the shaft of the suturing instrument. Each needle is separately actuated into a gap in the instrument's tip, through tissue suctioned into the opening of the vacuum sleeve and into a ferrule at each end of a loop of suture.

  • Patent number: 7407505
    Abstract: An instrument and method for suturing wound closures is provided having a handle, shaft and suture engagement mechanism. The instrument provides for multiple placements or “bites” of suture in tissues to enable a wide variety of suturing techniques, including the ability to “run” a suture. The instrument further facilitates suture knot tying. The method of this instrument provides for rapid and effective remote suture placement and knot tying.
