2:

• The medical device according to claim 1, characterised by that the layer of the abdominal wall (6a) is fixed to the sheets (1, 2) via fixing elements (4) passing through all of the fascias and muscle layers.

3:

• The medical device according to claim 1, characterised by that the fixing elements (4) are formed by transfascial sutures passing through the sheets (1, 2), as well as through the outer and inner fascia, furthermore through the abdominal wall muscle between them, made from monophile polypropylene, non-absorbing thread.

4:

• The medical device according to claim 3, characterised by that the transfascial sutures are U-shaped through the internal sheet (1) and also hold the peritoneum (10), and passing through the external sheet (2) they are knotted (4a) outside the outer fascia.

5:

• The medical device according to claim 1, characterised by that it has four fixing elements (4) located at symmetrically allocated positions as compared to the geometrical longitudinal axis (x) of the device (11).

6:

• The medical device according to claim 1, characterised by that the internal cylindrical surface of the central linking tube member (3) is a continuous smooth surface.

7:

• The medical device according to claim 1, characterised by that at least the tube member (3) is made from plastic mesh and/or woven plastic textile.

8:

• The medical device according to claim 1, characterised by that the internal surface of the tube member (3) linking the sheets (1, 2) is coated with a silicon-based material that causes easily releasable adhesion with the surface of the intestine.

9:

• The medical device according to claim 1, characterised by that the sheets (1, 2) are parallel to each other, and the geometric longitudinal axis (x) of the tube member (3) passes through the geometric centre point (o) of the sheets (1, 2).

10:

• The medical device according to claim 1, characterised by that the sheets (1, 2) are circular and have the same diameter (D).

11:

• The medical device according to claim 1, characterised by that it has a circular cylinder cross-section tube member (3), the diameter (d) of which is selected in accordance with the diameter of the stoma (7a) to be led through it.

12-14. (canceled)

16:

• The method in accordance with claim 15 wherein the transfascial sutures also encompass peritoneum.

17:

• The method in accordance with claim 15 wherein the transfascial sutures are non-absorbable, U-shaped, polypropylene monofilaments.

18:

• The method in accordance with claim 15 wherein the transfascial sutures are secured by a knot on side of the sheet opposite that adjacent to the musculo-aponeurotic layer.
