Ostomy barrier

1. An ostomy barrier for attaching an ostomy appliance to a peristomal skin surrounding a stoma, the ostomy barrier comprising:

an inlet opening for receiving a stoma; and

a barrier adhesive including a thicker portion and a thinner portion configured to improve flexibility of the ostomy barrier, wherein a thickness of the thicker portions is at least two times a thickness of the thinner portion, wherein the thinner portions comprise a plurality of indented lines extending horizontally from a peripheral edge to an opposite peripheral edge, wherein the plurality of indented lines extend generally parallel to user's waist, and wherein the plurality of indented lines are configured to function as living hinges to allow the ostomy barrier to crease and bend with a user when the ostomy barrier is attached to the user.

2. The ostomy barrier of claim 1 , wherein the barrier adhesive has a distal surface and a body-side surface, wherein the plurality of indented lines are provided on the distal surface, and wherein the ostomy barrier is configured to attached to a user by adhering the body-side surface to the user.

3. The ostomy barrier of claim 1 , wherein the barrier adhesive has a distal surface and a body-side surface, wherein the plurality of indented lines are provided on the body-side surface, wherein the inlet opening is surrounded by the thicker portion, and wherein the ostomy barrier is configured to attach to a user by adhering the body-side surface to the user.

4. The ostomy barrier of claim 1 , wherein the thicker portion has a thickness of about 0.045 inches to about 0.065 inches, and the thinner portion has a thickness of about 0.010 inches to about 0.015 inches.

5. The ostomy barrier of claim 1 , wherein the barrier adhesive is formed from at least one hydrocolloid adhesive.

6. The ostomy barrier of claim 1 , wherein the thicker portion is formed from a first material and the thinner portion is formed from second material that is different from the first material, wherein the first material is a hydrocolloid adhesive.

7. The ostomy barrier of claim 1 , wherein a backing layer is disposed on a distal surface of the barrier adhesive, and an ostomy pouch is attached to the backing layer on the distal surface of the barrier adhesive.

8. The ostomy barrier of claim 1 , wherein a backing layer is disposed on a distal surface of the barrier adhesive, and a body-side coupling ring is attached to the backing layer on the distal surface of the barrier adhesive, wherein the body-side coupling ring is configured to mate with a pouch-side coupling ring attached to an ostomy pouch for attaching the ostomy pouch to the ostomy barrier.
