A suture fastening device for forming a welded suture joint in situ includes a horn 8 and an anvil 16 movable relative to each other in a tubular shaft 3, and a source of energy 6 for actuating the horn and anvil within the shaft and relative to each other. Segments 20a, 20b of a suture to be joined are captured within the anvil and contacted by the horn for transfer of energy thereto during welding. A predetermined condition of the welded joint or of the horn and anvil is detected so as to control the delivery of energy to the segments during welding.
