A device for affixing a tubular medical accessory to a wall of a body passage is disclosed. The said device comprises a handle portion, a barrel portion and a working head portion, said barrel portion is fitted with a pushing rod displaceable along the barrel portion upon actuating the handle portion. The working head portion is fitted with a plurality of wings and levers and said wings are preloaded with a plurality of staples. Upon initial displacement of the pushing rod in a distal direction the wings are swiveled towards the medical accessory such that they abut it and stretch it together with the body passage in a radial direction. Upon still further displacement of the pushing rod the levers are swiveled and cause the staples to exit from the wings such that the staples pierce the accessory and the wall of the body passage and affix the accessory to the body passage.
