A wire loop type instrument for an endoscope has a control wire axially movably inserted in a flexible sheath, and a wire loop connected to the distal end of the control wire. The wire loop is formed by an elastic wire. When the control wire is advanced, the wire loop projects from the distal end of the flexible sheath and expands in a loop shape by its own elasticity. When the control wire is retracted, the wire loop is pulled into the distal end of the flexible sheath and folded. The elastic wire is a stranded wire formed by twisting together a plurality of thin metal wires. The control wire is formed by twisting together a pair of elastic wires extending from the rear end of the wire loop in the opposite direction to the direction of twist of each elastic wire.

A ring or rings adapted for endoluminal placement within the stomach, other hollow organ or vessel, and a method for deploying the rings is described. The rings create a small pouch with a reinforced stoma in the stomach for the treatment and control of obesity. An endoluminal suturing device for deploying a circumferential line of interrupted mattress suture bites is inserted into the patient's stomach via the patient's mouth. The distal gastric ring is preloaded on the distal end of the suturing device and is incorporated with suture loops from the double-armed sutures contained within the device. The suturing device can have an expandable area at its distal end that can expand its diameter to between approximately 10 mm and 150 mm. The circumference of this expanded area has a suction opening that is used to draw in tissue when a vacuum is applied to the device. Flexible cannulas containing long flexible suture needles are positioned radially around the circumference of the suction opening. The long needles are are adapted to be advanced through the drawn in tissue incorporating their attached suture material. The expandable area of the device is collapsed, and the device is withdrawn from the patient. With the distal ring anchoring the sutures beneath the incorporated tissue folds, a column of sutures exits the device's suction port as the device is withdrawn. A second, proximal ring is then incorporated with the sutures and may then be endoscopically lowered into the patient's stomach and positioned proximal to the distal ring. The sutures are endoscopically secured and cut, thereby fixing the two rings together with tissue incorporated between them.

An apparatus for sewing tissue especially useful for tissue ligation, is provided having a housing and a hollow shaft which extends from the housing. At the distal end of the shaft along its interior is a movable driver member disposed opposite a fixed member. A needle is pivotably mounted at one end to the driver member to extend, when the driver member is moved forward, through a slot in the fixed member and an opening in the shaft, and to retract back into the shaft when the driver member is moved backward. At the distal end of needle is a slotted hook for capturing a loop of suture. The free ends of the loop of suture extend through a hole of the fixed member. A lever pivotably mounted in the housing is coupled to the driver member to translate linear motion forwards or backwards to the driver member. In a method for sewing tissue, the needle is driven forward to extend from the apparatus and then through tissue adjacent tissue to be sewn. The loop of suture is then removed from the needle prior to its retraction leaving the loop of suture extending through the tissue. The apparatus is repositioned with the needle on the opposite side of the tissue to be sewn. The loop of suture is captured again on the needle, and then the needle is retracted with the loop of suture into the apparatus. While holding one end of the suture, the apparatus is removed and one side of the loop of suture is drawn through and around the tissue to be sewn. The mid section of the suture is thus behind the tissue and the suture ends on opposite sides of the tissue are available to facilitate securing or tying of the suture to close a wound or to ligate a tissue structure.
