A filter assembly for an enclosure, particularly for an ostomy bag, is described having an enclosure side, a first layer which is gas permeable, and an adsorbent layer comprising adsorbent particles dispersed in a fine fiber web. The enclosure side of the filter assembly includes an adhesive zone in which adhesive is present having an outer adhesive perimeter and a weld area surrounding at least a portion of the adhesive zone, where the filter assembly is heat-sealable to the enclosure at the weld area. A method of assembly is also described.

Disclosed herein is a urinary collection system including a urine collection bag and a vacuum chamber coupled to the urine collection bag. The vacuum chamber is positioned in a vertical orientation. A top end of the vacuum chamber includes a drainage inlet and a vacuum port, and a bottom end of the vacuum chamber includes a drainage outlet. An isolation chamber is disposed between the vacuum chamber and urine collection bag, where the isolation chamber is configured to prevent reflux of urine from the urine collection bag into the vacuum chamber. A vacuum tube extends between the vacuum chamber and a vacuum pump. A plunger valve in line with an outlet of vacuum chamber is transitioned to a closed state when a vacuum is applied to the vacuum chamber and transitioned back the open state when the vacuum is removed from the vacuum chamber.

A colostomy device, which can be referred to as an endoluminal stoma channel, is provided which incorporates a generally cylindrical membrane, with a ring located at either end: an inner luminal ring which is located within the bowel and an outer ring which is rolled over itself to abut against the skin, to which a colostomy bag may be attached. In a corresponding system (stoma discharge control system), the colostomy device (endoluminal stoma channel) is associated with a cover or cap that can facilitate control of discharge from the stoma, and various cover/cap structures are described. Corresponding methods are described.
