Abstract: A stoma seal is described for a controlled evacuation ostomy appliance. The stoma seal may have a liquid-responsive property, such as hydrophobic, hydrophilic or absorptive. The stoma seal may have a non-smooth surface, e.g., at a microstructure scale. The non-smooth surface may consist of tortuous channels, protruding seals, or a confronting apertured or porous layer. The liquid-responsive property and/or the non-smooth surface may facilitate separation of flatus from faecal matter and/or facilitate venting of flatus while obstructing stool.

Abstract: A stoma closure that includes a conformable portion for conforming to an individual's stoma. The conformable portion includes a sack containing particles. The conformable portion may include a gel that may be loose or be at least partly contained in a sack. The conformable portion may include foam. The conformable portion may be configured to permit venting of flatus, while obstructing the passage of liquid/solid stool.

Abstract: A controlled evacuation ostomy appliance including a collection pouch, and an urging device for applying a sealing force through the pouch wall to seal the stoma. The pouch wall may seal directly against the stoma, or the pouch may have an internal sealing member that is pressed by the pouch wall against the stoma. The urging device provides an adjustable sealing force. The pouch may be disposable. The urging device may be reusable with a replacement pouch.

Abstract: A controlled evacuation ostomy appliance comprises a membrane that is urged into sealing engagement with a stoma, by the generation of radial tension in the membrane. A tensioning device applies tension, with respect to the stoma, at one or more positions that are (i) outboard of the periphery of the projecting portion of the stoma, and/or (ii) between the level of the peristomal skin and the level of the most projecting part of the stoma. Tension limiting means are disclosed. The membrane may be gas-permeable to allow flatus to be vented.

Abstract: An ostomy plug is described comprising first and second chambers having adjacent ends coupled to, and in fluid communication with, each other. The first chamber may be for insertion into a stoma. The second chamber may contain fluid for inflating the first chamber when the second chamber is squeezed or otherwise compressed. The plug may have a figure-of-eight configuration. The plug may be configured to permit venting of flatus while obstructing escape of other body waste from the stoma. The plug may incorporate an insertion aid for aiding insertion into a stoma. The plug may also incorporate a device for regulating the inflation pressure of the fluid to avoid undesirably high inflation pressures in the stoma.

Abstract: A controlled evacuation ostomy appliance includes an attachment device for attaching the appliance to a wearer, a seal for sealing against stomal tissue, and a restrainer. The restrainer restrains the seal relative to the attachment device and transfers a sealing force (or its reaction) between the attachment device and the seal.
