1. Closure device for an opening in a layer of tissue, comprising:
- a plurality of separate wings which provide bearing areas on tissue surrounding the opening; and
a base part;
wherein;
each of the wings are held by means of a respective film hinged joint for swiveling movement on the base part at only end of the closure device;
the joints are fixed on an upper surface of the base part, said upper surface facing the tissue when bearing areas bear on the tissue; and
the wings are arranged for swiveling movement on the base part such that in a flapped-in position neighboring wings have partially overlapping contact with one another such that no part of the wings protrudes laterally over the base part and the arrangement of the wings in the flapped-in position has a circumference which is identical to or smaller than that of the base part.

24. A closure system, said closure system comprising:
-
a plurality of separate wings which provide bearing areas on tissue surrounding an opening in the tissue; and a base part; wherein each of the wings are held by means of a respective film hinged joint for swiveling movement on the based part at only end of the closed device; the joints are fixed on an upper surface of the base part, said upper surface facing the tissue when bearing areas bear on the tissue; and the wings are arranged for swiveling movement on the base part such that in a flapped-in position neighboring wings have partially overlapping contact with one another such that no part of the wings protrudes laterally over the base part and the arrangement of the wings in the flapped-in position has a circumference which is identical to or smaller than that of the base part; said applicator device comprising; a positioning element which is longitudinally displaceable in the trocar sheath and by means of which the wings of the closure device are transferable from the flapped-in position in which the closure device is displaceable in the trocar sheath to a flapped-out position; a holding mandrel for holding and positioning the closure device, said holding mandrel having a hollow interior through which a suture thread is guided; and a first centering means for centering the positioning element in the trocar sheath; wherein the positioning element provides a second centering meals for the holding mandrel which substantially prevent transverse movability of the holding mandrel relative to the positioning element. - View Dependent Claims (25, 26, 27, 28)
