1. An ostomy appliance to provide continence to a stoma, comprising:
- a collapsed waste collection pouch for receiving stomal waste, the pouch having an aperture attached to a proximal end of said ostomy appliance and sized to receive waste therefrom;
a closure region of said pouch comprising a surface extending substantially parallel and proximal to said aperture;
whereinthe limits of said closure region are defined by folds;
said folds restrict waste reaching said aperture from moving past said closure region into the remainder of the pouch, when attached as a collapsed pouch to said ostomy appliance; and
wherein said pouch comprises a folded configuration having a polygonal cross-section comprising a shape formed by folds comprising at least three crease lines, and wherein said polygonal cross-section comprises a shape formed by folds comprising at least two crease lines at an angle to said at least three crease lines.

32. A folded pouch adapted for use with an ostomy appliance to provide continence to a stoma, comprising:
-
a pouch body having an aperture configured to fit against a proximal end of said ostomy appliance and sized to receive waste therefrom; a frame configured to attach to said ostomy appliance and fit said aperture thereto; a closure region of said pouch body comprising a surface extending substantially parallel and proximal to said aperture; wherein folding of said pouch restricts waste reaching said aperture from moving past said closure region into the remainder of the pouch body, when attached as a collapsed pouch to said ostomy appliance; and wherein said pouch body comprises a folded configuration having a polygonal cross-section comprising a shape formed by folds comprising at least three crease lines, and wherein said polygonal cross-section comprises a shape formed by folds comprising at least two crease lines at an angle relative to said at least said three crease lines. - View Dependent Claims (33, 34)

35. An ostomy cap for sealing a surgical stoma comprising:
-
a folded ostomy pouch; and a pressure-releasing pouch restraint positioned to prevent the pouch from deploying from its collapsed state below a selected threshold of pressure received from within the abdominal cavity;
wherein the folding pattern of the folded ostomy pouch is adjustable to one of a plurality of predetermined folding patterns; andsaid selected threshold of pressure is changeable, according to said folding pattern.
