A balloon-like member is received in the bowel and inflated to seal the stoma. The member includes a thin flexible wall defining an opening. A rigid or semi- rigid cap retains the member and closes the opening in the member wall. Skin comfortable adhesive adheres the edge of the cap to the tissue surrounding the stoma. A flexible dilation tube facilitates insertion of the member and cooperates with a pump to inflate the member. The cap is preferably removeably attached to a standard two-piece ostomy faceplate and is provided with a filter element to vent flatus.

Why it's free to use
- Filed February 28, 2003 and granted March 29, 2011. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended February 28, 2023.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by February 28, 2025.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
