Abstract: A closure system for a drainable ostomy appliance, which appliance includes a body side wall and a non-body side wall sealed to one another to define a collection cavity and a neck portion terminating in a discharge outlet. The closure system includes a first portion on the body side wall having first and second closure members defining a gap therebetween and a second portion on the non-body side wall having a third closure member having an enlarged head portion. In an open state, the neck portion is unfolded. In a closed state, the first closure member is folded onto the third closure member with an edge of the first member engaging the enlarged head through the side wall sheet material, and the first, second and third closure members folded over onto the non-body side wall at a tight fold to seal the discharge outlet.

Abstract: A drainable ostomy pouch outlet includes a single-piece closure member including at least one transversely-extending fold-line. The at least one transversely-extending fold-lines are configured to facilitate folding up and closing of the outlet. The single-piece closure member may also include at least one axially-extending or slanted fold-lines intersecting the at least one transversely-extending fold-line, configured to facilitate opening of the outlet.

Abstract: A faceplate assembly for an ostomy pouch system including an invertible stoma collar is provided. The invertible stoma collar protrudes toward a stoma and defines an inlet opening. The invertible stoma collar is formed from a flexible material having an elastic memory, such that the stoma collar hugs the stoma as the stoma is received through the inlet opening, and becomes inverted. The inverted stoma collar has a tendency to regain its original shape, and thus, applies sufficient pressure to seal around the stoma without strangulating the stoma.

Abstract: An ostomy appliance includes an outer wall having first and second opposed sides joined at an outer periphery, an inlet and a filter assembly, wherein the outer wall defines an interior volume comprising a collection area and a filter flow path in fluid communication with the collection area. The filter flow path fluidically connects the filter assembly to the collection area. The ostomy appliance further includes one or more flow elements between the first side and the second side, the one or more flow elements disposed between the collection area and the filter assembly. The one or more flow elements may be sized and arranged to permit gas venting from the collection area to the filter assembly and restrict liquid and/or solid flow from the collection area to the filter assembly.

Abstract: An ostomy barrier includes an inlet opening for receiving a stoma and a barrier adhesive including a plurality of thicker portions and a plurality of thinner portions. The plurality of thinner portions are configured and arranged to improve the flexibility of the ostomy barrier.

Abstract: A ostomy pouch filter includes a first layer of deodorizing media, a second layer of deodorizing media, a vapor barrier layer disposed between the first layer and the second layer, a first seal on the first layer on a side of the first layer opposite to the vapor barrier layer, and a carrier film connected to the first layer with the first seal. In addition, the ostomy pouch filter may include a cover film. An ostomy pouch includes a sidewall to which the ostomy pouch filter is sealed.

Abstract: An ostomy barrier includes an adhesive layer having a body-facing side, a distal side opposite to the body-facing side, and an opening, a seal substantially aligned with the opening, the seal having an aperture configured to receive a stoma therein, and a flexible connector extending between the seal and the adhesive layer to connect the seal to the adhesive layer. The flexible connector formed from a flexible material to allow relative movement between the seal and the adhesive layer.

Abstract: A faceplate assembly for an ostomy pouch system including an invertible stoma collar is provided. The invertible stoma collar protrudes toward a stoma and defines an inlet opening. The invertible stoma collar is formed from a flexible material having an elastic memory, such that the stoma collar hugs the stoma as the stoma is received through the inlet opening, and becomes inverted. The inverted stoma collar has a tendency to regain its original shape, and thus, applies sufficient pressure to seal around the stoma without strangulating the stoma.

Abstract: An ostomy pouch and high-performance gas filter assembly therefor, in which the filter assembly includes an envelope defining a filter chamber containing a radial flow deodorizing filter pad. The pad's opposite faces are joined to the inner surfaces of the envelope in such a way that the periphery of the pad is fully exposed within the chamber. A first passage extends through the filter and communicates with a first opening in a wall of the envelope over which a first microporous membrane extends. A second opening extends through the opposite wall of the envelope at a distance spaced laterally from the first opening, and a second hydrophobic microporous membrane extends over the second opening. In a preferred embodiment, the filter pad is oblong in shape and has a second passage spaced laterally from the first passage and communicating with the second aperture.

Abstract: A method for producing a soft convex adhesive wafer for attaching an ostomy appliance to a peristomal skin surface surrounding a stoma. In one embodiment, the method includes providing a resilient laminating pad adapted for being displaced to and fro in a laminating direction and that exerts a laminating pressure in the laminating direction, providing a plane counter-pressure surface at substantially right angles to the laminating direction, placing the wafer on the counter-pressure surface, and displacing the laminating pad in the laminating direction so that laminating pressure is exerted on an entire distal surface of the wafer by the laminating pad.

Abstract: A convex adapter for ostomy appliances is disclosed, the adapter including an adapter ring formed entirely of a soft, tacky, moisture-absorbent and swellable, hydrocolloid-containing adhesive material, one that retains its integrity on hydration and is shape-recoverable when compressive forces are removed, and a thin substantially non-stretchable cover film extending over and beyond the convex bodyside surface of that ring. The film is removably attached to the ring and is preferably transparent (or translucent) so that at least the outline of the ring may be seen through it. A flexible but substantially non-stretchable release sheet is removably attached to the opposite pouchside surface of the ring and may be peeled away from the ring during an initial step in the use of the product.

Abstract: An adhesive wafer for attaching an ostomy appliance to a peristomal skin surface surrounding a stoma has an integrally molded adhesive layer made of a skin barrier material, a distal surface covered by a flexible backing layer, and a proximal bodyside surface contoured so the adhesive layer has a thin peripheral portion and thick central portion surrounding a stoma-receiving aperture. A set of at least two wafers is provided in one embodiment, wherein individual wafers have differing central portion surface topography, and different stoma receiving apertures. To produce a closely fitting wafer for a given stoma, a method of producing wafers includes providing a representation of the topography of the peristomal surface and the stoma, and, using the representation, manufacturing a mold having a surface configuration substantially matching the topography of the peristomal surface and stoma.
