Abstract: A method for closing a wound in a tubular organ using a suture thread attached to a suture needle. The method includes grasping a first part of the suture thread by a grasper inserted in the tubular organ after the suture thread has been passed through tissue surrounding the wound at a first position; moving the first part away from the first position by moving the grasper grasping the first part along a longitudinal axis of the grasper; grasping a second part of the suture thread located between the first part and the first position by the grasper; and moving the second part away from the first position by moving the grasper grasping the second part along the longitudinal axis of the grasper.
