Abstract

A stomal insert for conducting waste content from an intestinal portion in an abdominal cavity through a stoma in an abdominal wall comprising; a cover for covering the stoma; a fixation element for anchoring the stomal insert to a visceral side of the abdominal wall; and a pliable, axially elastic tube interconnecting said cover and said fixation element and sized to apply a tensile force to said cover and to said fixation element.

Claims

1. An ostomy port for conducting waste content from a portion of intestine on a visceral side of an abdominal wall to an exterior of said abdominal wall, through a stoma of said intestine, comprising:

a tube, axially elastic along a longitudinal extent, and sufficiently pliable for being radially and reversibly collapsible upon constriction within said portion of intestine;

an elastic fixation element attached to a visceral-side opening of said tube, and insertable into said visceral-side intestinal portion to anchor said port; and

an elastic stoma cover, attached to an exterior-side opening of said tube, widening therefrom, and extending back over an exterior-side region of the ostomy port for contacting a surface of the exterior abdominal wall distanced from the external-side tissue of the stoma, forming a ring-shaped covering region sized to externally surround the external-side tissue of the stoma;

said tube being of a length to extend longitudinally from a proximal side connected with said stoma cover along said length of intestine extending distally from said stoma and cross said abdominal wall such that said tube reaches said visceral side of said abdominal wall;

the stoma cover being deformable such that any point on a circumference of the stoma cover may be displaced in the axial direction by up to a predetermined maximum level;

wherein the tube is adapted to bend for accommodating relative motion between the stoma cover and the fixation element due to displacement by changes in tissue position while inserted across said abdominal wall.

2. The ostomy port according to claim 1 characterized by the pressure applied by said fixation element due to said tensile force decreasing to less than 10 mmHg when colonic pressure is equal to or greater than approximately 10 mmHg.

3. The ostomy port according to claim 1 wherein said tube includes a material of durometer ranging from 5 to 50 shore A.

4. The ostomy port according to claim 1 wherein said tube comprises a material of durometer ranging from 20-30 shore A.

5. The ostomy port according to claim 1 wherein said fixation element includes a material of a durometer ranging from 5 to 50 Shore A.

6. The ostomy port according to claim 1 wherein said fixation element is a balloon and wherein said balloon includes a seamless exterior surface.

7. The ostomy port according to claim 1 wherein said fixation element deforms in an axial direction when pressed against the abdominal wall.

8. The ostomy port according to claim 7 wherein pressure applied by said fixation element on the abdominal wall ranges from 1 to 200 mmHg.

9. The ostomy port according to claim 1 wherein said cover includes an elastic material of a durometer ranging from 5 to 50 Shore A.

10. The ostomy port according to claim 1 wherein said cover is deformable by 5 mm in an axial direction.

11. The ostomy port according to claim 1 wherein said cover is substantially mushroom-shaped.

12. The ostomy port according to claim 1 wherein said cover includes a shape which is adjustable to variations in abdominal wall thickness.

13. The ostomy port according to claim 1, further comprising a gas filtering mechanism.

14. The ostomy port according to claim 1, further comprising an active gas release mechanism for release of flatus.

15. The ostomy port according to claim 14 wherein the active gas release mechanism includes a valve.

16. The ostomy porting according to claim 1 wherein said tube, said cover, and said fixation element are integrally formed in said ostomy port.

17. The ostomy port according to claim 16 further comprising an integral waste collection bag.

18. The ostomy port according to claim 1 comprising a deformable cap for providing a visual indication of an intra-colonic pressure of approximately 100 mmHg or greater.

19. The ostomy port according to claim 1 wherein said fixation element deforms in an axial direction when pressed against the abdominal wall.

20. The ostomy port according to claim 1, further comprising:

a cap for sealing said exterior-side opening;

wherein said cap includes a shell for accommodating a waste content collection bag.

21. The ostomy port according to claim 20 wherein said waste content collection bag is deployable from said shell upon sensing of an intra-colonic pressure of approximately 100 mmHg or greater.

22. The ostomy port according to claim 20 wherein said waste collection bag is deployed through a removable cover.

23. The ostomy port according to claim 20 wherein said tube includes an attachment mechanism for attaching said waste content collection bag.

24. The ostomy port according to claim 23 wherein said attachment mechanism includes a snap-and-fit arrangement for securing said waste content collection bag to said tube.

25. The ostomy port according to claim 1, wherein said predetermined maximum level is 10 mm.

26. The ostomy port according to claim 1 wherein said tube includes an attachment mechanism for attaching a waste content collection bag.

27. The ostomy port according to claim 26 wherein said attachment mechanism includes a snap-and-fit arrangement for securing said waste content collection bag to said tube.

28. The ostomy port according to claim 1, wherein a portion of said cover is invertable to expose the external-side tissue of the stoma.

29. The ostomy port according to claim 1, wherein said fixation element deforms non-uniformly, upon said relative movement including a non-axial component, such that pressing against the visceral-side intestinal portion is maintained below said predetermined maximum level.

30. The ostomy port according to claim 1, wherein said stoma cover deforms non-uniformly, upon said relative movement including a non-axial component, such that pressing against the exterior abdominal wall is maintained below said predetermined maximum level.

31. The ostomy port according to claim 1, wherein the tube is adapted to allow peristaltic propelling of waste content.
