Method and device and device for inserting a tubular prosthesis having a retainer projecting transversely at each end thereof, said retainer being resiliently foldable towards the axis of said tubular element, into a tracheoesophageal fistula. A loading tube is passed over the prosthesis the retainers being folded projecting substantially axially from the ends of the prosthesis, and the loading tube with the prosthesis enclosed by the loading tube is passed through the fistula from one side of the tracheoesophageal wall and then the loading tube is partly withdrawn the prosthesis being held stationary by a tool inserted into the tube from the other end thereof so that one retainer will be released and will unfold at the other side of the wall. The loading tube is withdrawn further in order that the other retainer will be unfolded at said one side of the tracheoesophageal wall. The loading tube is withdrawn from the prosthesis which is left in the fistula with the retainers positioned one at each side of the wall. |
