One embodiment of the stitching device utilizes a pair of surgical needles or incision members joined by a single length of suture material. There are also disclosed disposable loading units for providing suture - needle assemblies to the suturing apparatus. Also disclosed are methods of suturing an artificial heart valve to heart tissue using the disclosed apparatus.
