Devices and methods for treating accidental bowel leakage

1. A method for treating fecal incontinence comprising:

placing a body liner at least partially within the intergluteal cleft, the body liner having a longitudinal axis, a body-facing surface and a rear surface opposite the body-facing surface, wherein the body liner comprises at least one adhesive region on the body-facing surface of the body liner, and wherein the body liner is formed from a plurality of liner layers including a top sheet, a back sheet, and a core member,

wherein each of the plurality of liner layers is liquid absorbent, and

wherein placing the body liner at least partially within the intergluteal cleft places the body-facing surface into contact with skin of the intergluteal cleft and comprises folding the body liner along the longitudinal axis,

wherein the core member is positioned between the top sheet and the back sheet, and wherein the top sheet has a shape comprising a first lobe on a first side of the longitudinal axis and a second lobe on a second side of the longitudinal axis.

2. The method of claim 1 wherein the body liner has a longitudinal axis, and wherein placement of the body liner at least partially within the intergluteal cleft comprises folding the body liner along the longitudinal axis.

3. The method of claim 1 wherein the core member is circular or oval.

4. The method of claim 1 wherein the shape of the top sheet further comprises a third lobe on the first side of the longitudinal axis and a fourth lobe on the second side of the longitudinal axis.

5. The method of claim 4 wherein the back sheet has a shape that is the same as the shape of the top sheet.

6. The method of claim 1 wherein the back sheet and the top sheet are at least partially bonded together.

7. The method of claim 6 , wherein the back sheet and top sheet are bonded together around a periphery of the top sheet.

8. The method of claim 7 , wherein the back sheet and top sheet are bonded together such that at least 80 percent of the top sheet remains unbonded.

9. The method of claim 8 wherein the back sheet and top sheet are bonded together such that at least 90 percent of the top sheet remains unbonded.

10. The method of claim 1 wherein the top sheet is configured to move fluid within the top sheet at a first wicking rate in a first direction, a second wicking rate in a second direction, and a third wicking rate in a third direction, wherein first and second directions are within a plane of the body liner, the first direction is perpendicular to the second direction, and the third direction is perpendicular to the plane of the body liner.

11. The method of claim 1 wherein the body liner is configured to be flushable.

12. The method of claim 11 wherein at least 90 percent of the body liner is formed from one or more biodegradable materials.

13. The method of claim 1 wherein placement of the body liner at least partially within the intergluteal cleft comprises placing the body liner such that at least a portion of the body liner extends out of the intergluteal cleft.

14. A method for treating fecal incontinence comprising:

placing a body liner at least partially within the intergluteal cleft, the body liner having a body-facing surface and a rear surface opposite the body-facing surface, wherein the body liner comprises at least one adhesive region on the body-facing surface of the body liner, and wherein the body liner is formed from a plurality of liner layers including a top sheet, a back sheet, and a core member,

wherein each of the plurality of liner layers is liquid absorbent,

wherein placing the body liner at least partially within the intergluteal cleft places the body-facing surface into contact with skin of the intergluteal cleft,

wherein the top sheet is configured to move fluid within the top sheet at a first wicking rate in a first direction, a second wicking rate in a second direction, and a third wicking rate in a third direction, wherein first and second directions are within a plane of the body liner, the first direction is perpendicular to the second direction, and the third direction is perpendicular to the plane of the body liner, and

wherein the top sheet is configured such that the third wicking rate in the top sheet is greater than the first and second wicking rates in the top sheet.

15. The method of claim 14 wherein the top sheet is configured such that the first wicking rate in the top sheet is greater than the second wicking rate in the top sheet.

16. The method of claim 15 wherein the body liner has a longitudinal axis along which the body liner is folded when placed at least partially in the intergluteal cleft, and wherein the first direction is parallel to the longitudinal axis.

17. The method of claim 15 wherein the body liner has a longitudinal axis along which the body liner is folded when placed at least partially in the intergluteal cleft, and wherein the second direction is parallel to the longitudinal axis.

18. A method for treating fecal incontinence comprising:

placing a body liner at least partially within the intergluteal cleft such that at least a portion of the body liner extends out of the intergluteal cleft by a distance less than about 2.5 cm from the intergluteal cleft, the body liner having a body-facing surface and a rear surface opposite the body-facing surface, wherein the body liner comprises at least one adhesive region on the body-facing surface of the body liner, and wherein the body liner is formed from a plurality of liner layers including a top sheet, a back sheet, and a core member,

wherein each of the plurality of liner layers is liquid absorbent,

wherein placing the body liner at least partially within the intergluteal cleft places the body-facing surface into contact with skin of the intergluteal cleft.
