Abstract

An artificial Ostomy containment device comprising an implantable intra-abdominal sleeve adapted to interfere with movement of a closure assembly positioned within the sleeve; and a closure assembly comprising a hollow stomal insert sized and shaped to conduct waste content from an intestinal portion in an abdominal cavity through said insert and out of a stoma, and a fixation element coupled to said stomal insert sized and positioned to interfere with said intra-abdominal sleeve.

Claims

1. An artificial Ostomy containment device comprising:

a closure assembly adapted to conduct waste content from an intestinal portion in an abdominal cavity and out of a stoma;

a fixation element sized and positioned to interfere with movement of said closure assembly;

a stomal cover sized and shaped to cover the stoma from outside the abdominal cavity;

a pressure sensing mechanism for sensing a pressure; and

a pressure indicator externally positioned on the device for mechanically communicating to a user an indication of said sensed pressure.

2. The containment device according to claim 1 wherein the fixation element is an inflatable balloon.

3. The containment device according to claim 1 wherein the stomal insert comprises a lumen for conveying an expansion fluid to an inflatable balloon.

4. The containment device according to claim 1 wherein the closure comprises an inflation valve for introducing the expansion fluid into a lumen.

5. The containment device according to claim 1 wherein the fixation element is a pre-shaped elastically deformable element configured to be inserted into said intestinal portion.

13. The containment device according to claim 1 wherein said stomal cover includes a flatus release mechanism for controlling a pressure buildup in said stomal insert.

14. The containment device according to claim 1 comprising a safety mechanism for releasing bowel waste content when a colonic pressure reaches a predetermined value.

15. The containment device according to claim 1 wherein the closure comprises a material of durometer ranging from 20-80 Shore A for allowing peristaltic propelling of the waste content.

20. The containment device according to claim 1 wherein the fixation element comprises a non-collapsible balloon.

21. The containment device according to claim 1 comprising an inflatable balloon inside the stomal insert for blocking a flow of the waste content.

22. The containment device according to claim 1 wherein the fixation element comprises a broadening of the stomal insert.

40. The containment device according to claim 1 wherein a shape of said stomal cover is invertible to allow access to the stoma.

42. The containment device according to claim 1 comprising a disposable bag assembly for collecting waste content from the device, said assembly comprising:

a bag housing attachable to a proximal end of said stomal insert; and

a waste content collection bag folded in said bag housing;

43. The containment device according to claim 42 wherein the bag housing is replaceable.

44. The containment device according to claim 42 wherein the bag housing is permanently affixed to the stomal insert.

54. The containment device according to claim 1 wherein said pressure sensing mechanism is configured to sense a pressure from said waste content.

55. The containment device according to claim 1 wherein said pressure sensing mechanism is configured to sense an inflation pressure in said fixation element.

56. The containment device of claim 13 wherein said flatus release mechanism is controllable by a user of the device.

57. The containment device of claim 13 wherein said flatus release mechanism includes a sealable opening in said stomal cover configured for allowing passage of flatus.

58. The containment device of claim 1 comprising a waste blocking mechanism for preventing waste content from flowing out of the device when a waste content collection bag is unattached to the device.

59. The containment device of claim 58 wherein said waste blocking mechanism includes a one-way valve.

60. The containment device of claim 1 wherein said fixation element is coupled to a stomal insert in said closure.

61. The containment device of claim 1 wherein said stomal cover is coupled to a stomal insert in said closure.
