A mounting tool (20) for mounting an anastomotic device (10, 200) to an end (220, 221)of a tubular structure (90) comprises a receiving portion for receiving a rigidpart (11, 13) of said device (10, 200) and a conical portion with a large end facingsaid rigid part (11, 13) having a diameter larger than or equal to the rigid part(11, 13) and a small end. The conical portion comprises a releasable portion andis insertable into the elastic part (12) arranged inside the tubular structure(90) for expanding the diameter thereof and for passing the elastic part (12)beyond the large end and onto a rigid part (11, 13) arrangeable at the receivingportion. A method for mounting a device (10, 200) to an end (120, 121) of a tubularstructure (90) comprises arranging a rigid part (11, 13) of said device (10, 200)at a receiving portion of a mounting tool (20), inserting a small end of a conicalportion of said mounting tool (20) into an elastic part (12) of said device (10,200), wherein the elastic part (12) is arranged at the end (120, 121) of the tubularstructure (90), and passing the elastic part (12) along said conical portion,thereby expanding the elastic part (12) until passing over the large end to bereceived in the rigid part (11, 13) arranged at the receiving portion.
