Abstract: Disclosed is a method and device for suturing tissue and implanting prosthetic grafts, the device includes 1) at least one flexible cannula having a means to remotely manipulate the configuration of its distal end, and 2) a suction capsule component that may be incorporated or fit within or about the flexible cannula. The flexible cannula and suction capsule component are of a size that allows them to be inserted, independently or as a unit, into a natural body orifice or small surgical incision. The suction component may be used to draw tissue into an opening in the suction capsule component, enabling the at least one needle to be advanced through the at least one flexible cannula thereby passing through the tissue held by the at least one opening in the suction capsule component and thereby delivering the attached suture to the tissue.

Abstract: 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.
