A device and method of suturing closed an opening and ligating a vessel or duct comprising removable tissue puncturing means (22) or vessel surrounding means establishing a continuous channel (24) through said tissue or around said vessel from each side. A completed channel (24) is formed and suture material (26) is threaded through the channel making a complete loop. The thread is secured at an anvil (30) independent from said puncturing/surrounding means. The puncturing/surrounding means is retracted leaving the thread, which is then tensioned closing the opening or occluding the vessel. The suture thread is secured and cut, forming a closed loop with overlapping ends. An energy transmitting device (38) melts the suture thread ends together forming a weld. The anvil (30) is removed leaving a knot-free completed stitch or ligature.
