Abstract

A stoma adapter is described that is especially suited to a recessed stoma or a flush stoma. The stoma adapter effectively extends the discharge passage from the stoma, protects peristomal skin, and forms a bridge at the interface between the stoma and an ostomy appliance. The stoma adapter contains a substantially unobstructed discharge passage, at least for effluent flowing in a discharge direction. The stoma adapter includes a seal for sealing against the bowel wall. The stoma adapter has collapsing, expanding, flexible and reinforced designs.

First claim

We claim:

1. An ostomy appliance, comprising:
a proximal end portion configured for insertion into a stoma and/or into a peristomal mouth surrounding a recessed stoma;
a fluid inlet; and
one or more openings formed in an outer periphery of the proximal end portion;
wherein each opening of the one or more openings is in fluid communication with the fluid inlet such that a fluid injected via the fluid inlet passes through the one or more openings.

2. The ostomy appliance of claim 1 , wherein the proximal end portion further comprises a bolster.

3. The ostomy appliance of claim 2 , wherein the one or more openings are formed in the bolster.

4. The ostomy appliance of claim 2 , wherein the bolster is configured to be inflated by the fluid.

5. The ostomy appliance of claim 1 , wherein the one or more openings comprises a plurality of openings.

6. The ostomy appliance of claim 5 , wherein the plurality of openings are microscopic in size.

7. The ostomy appliance of claim 1 , wherein the outer periphery of the proximal end portion is configured to contact a bowel wall; and
wherein the one or more openings are configured to permit the fluid to flow into one or more gaps between the bowel wall and the outer periphery of the proximal end portion.

8. The ostomy appliance of claim 1 , further comprising an effluent passage fluidly isolated from the one or more openings.

9. The ostomy appliance of claim 1 , wherein the fluid inlet is formed in a distal end portion of the stoma adapter.

10. A kit comprising the ostomy appliance of claim 1 ;
wherein the kit further comprises an injector containing the fluid and configured to inject the fluid via the fluid inlet.

11. The kit of claim 10 , wherein the fluid comprises a sealant configured to set into a rigid or semi-rigid state.

12. A method, comprising:
inserting a proximal end portion of a stoma adapter into a stoma or a peristomal mouth surrounding a recessed stoma; and
injecting a sealant into the stoma adapter;
wherein the sealant passes through one or more openings formed in an outer surface of the proximal end portion to thereby form a seal with soft tissue.

13. The method of claim 12 , wherein injecting the sealant inflates a bolster of the proximal end portion.

14. The method of claim 12 , wherein the one or more openings comprises a plurality of openings.

15. The method of claim 14 , wherein the plurality of openings are microscopic in size.

16. The method of claim 12 , wherein the sealant sets to a rigid or semi-rigid state.

17. The method of claim 12 , wherein injecting the sealant inflates a bolster of the proximal end portion to thereby cause the bolster to contact a bowel wall.

18. The method of claim 17 , wherein the sealant fills one or more gaps formed between the bolster and the bowel wall.

19. A stoma adapter, comprising:
a proximal end portion, the proximal end portion comprising:
an inflatable bolster having an outer periphery; and
a plurality of openings formed in the outer periphery and configured to permit a sealant to flow out of the inflatable bolster; and

an effluent passage extending through the stoma adapter.

20. The stoma adapter of claim 19 , wherein the plurality of openings are microscopic in size.

21. The stoma adapter of claim 19 , wherein the inflatable bolster is annular.

22. A method of using the stoma adapter of claim 19 , the method comprising:
inserting the proximal end portion into a stoma or a peristomal mouth surrounding a recessed stoma; and
injecting the sealant into the inflatable bolster, thereby inflating the inflatable bolster;
wherein the sealant passes through the plurality of openings to thereby form a seal with soft tissue.
