An ostomy appliance body side member or an ostomy appliance comprising an adhesive wafer having a first adhesive surface for securing the appliance to the user's skin, said wafer having a second surface being covered with a carrier sheet which wafer has a hole for receiving a stoma wherein a part of the adhesive wafer surrounding the stoma shows balanced plastic and elastic properties allowing an adaptation of the size of the hole of the ostomy appliance to a stoma by enlarging the hole for accommodating the stoma by rolling up the inner rim thereof forming a torus and wherein a part of the second surface of the wafer surrounding the hole shows surface properties compatible with the first adhesive surface of the adhesive wafer locking the torus to the second surface in its rolled position by the contact between the second surface and the first adhesive surface enables a simple, safe and reliable customisation of the hole of a body side member without the use of tools and at the same time provides means for reducing the risk of causing injury to or constriction of the stoma.

An ostomy appliance having a face plate assembly and inner and outer pouches joined thereto, has its outer pouch provided with one or more peripherally-extending sealing seams that allow the walls of the outer pouch to be separated by peeling forces applied in directions transverse to such seam or seams. In preferred embodiments, the sealing seam, also peelably join the peripheral edges of the outer pouch to those of the inner pouch. A method of disposing of the pouch assembly of such an ostomy appliance is also disclosed.

A faceplate for an ostomy appliance is disclosed in which a unitary release sheet covers both the bodyside (rear) surface of an adhesive skin barrier layer and the surrounding adhesive surface of an outwardly-projecting porous covering layer. The barrier layer is beveled to a feathered outer edge and the release sheet contacts the adhesive surface of the covering layer immediately adjacent the outer edge of said barrier layer. A continuous in-line method for making such faceplates is disclosed.

A temporary ostomy appliance is disclosed, including a catheter for extending through the abdominal wall into the intestine. The catheter may be a transcecal catheter for extending through the cecal valve into the ileum. A portion of a catheter that extends through the cecal valve is made collapsible when the catheter is empty. The collapsed portion expands to permit passage of effluent. A balloon carried on the catheter is preformed with a shape and size in order to permit inflation without elastic stretching of the balloon wall material. A filament is provided for permitting a portion of the catheter to be fastened to internal body tissue by surgical sutures or staples. In order to release the fastening without further surgery, the filament is withdrawn by pulling on a proximal portion outside the body.

An ostomy appliance comprising a front wall and a rear wall of flexible material forming a bag, the rear wall having an opening into the bag by which waste material can enter the bag and one of the walls has one or more vents through which gas may escape from the bag and having a filter covering said vent wherein gas inlet and outlet openings and provided in communication with a filter body, the arrangement being so that in use gas flows through the filter from the inlet opening to the outlet opening, such gas flow being confined to said filter body, wherein the gas inlet opening to the filter is provided with at least two separate and independent closed pathways having separated inlet openings communicating with the bag and separate and independent outlet openings communicating with the inlet opening of the filter, and wherein each of the outlet openings of the separate pathways are covered by a microporous membrane shows improved resistance against blocking of the inlet opening of filter.
