Device for collecting fecal discharge in incontinent patients
First Claim
1. A collector for fecal discharge comprising:
- a self-expanding resilient collection component having an open proximal end, an open distal end and a lumen along the longitudinal axis of said component, said collection component lumen providing a passage connecting said open proximal and distal ends, said collection component being expandable from a compressed configuration to an expanded configuration, the collection component formed by a plurality of resilient arms interconnected to define interspaces therebetween and to define the contour of the collection component, wherein adjacent arms of said component are resiliently biased away from each other and are arranged such that said resilient arms exert outwardly directed radial pressure upon a subject'"'"'s rectal walls upon deployment within the subject'"'"'s rectum,wherein the resilient arms impel the collection component from the compressed configuration towards the expanded configuration, andwherein said radial pressure generated by the resilient arms is less than the pressure exerted by adjacent rectal walls during peristaltic contractions;
a housing sheath comprising a flexible and resilient material overlaying at least one of the inner or outer contour of said collection component while maintaining the open proximal and distal ends of said component and maintaining patency of the lumen connecting said open ends; and
a transit component providing a conduit for fecal discharge to migrate from the collection component to a receptacle therefor, said transit component comprising a flexible substantially tubular sheath having a first open end, a second end, and a lumen, said transit component lumen connecting the first open end and the second end, wherein the first open end of the transit component engages with the proximal end of the collection component.

Abstract
A collector for fecal discharge is provided comprising a self-expanding resilient collection component, a housing sheath and a transit component. The collection component has an open proximal and distal end and a lumen connecting them. The component comprises interconnected resilient arms circumscribing its contour, wherein adjacent arms are resiliently biased away from each other for exerting outwardly radial pressure for expanding and anchoring the component to rectal walls upon deployment. The housing sheath comprises a flexible and resilient material overlaying at least one of inner or outer contour of collection component without interfering with or blocking its ends or lumen. The transit component provides a conduit for fecal discharge to migrate from collection component to a receptacle and comprises a flexible, tubular sheath having a first open end connected to a second end by a lumen, wherein the first end engages with the proximal end of the collection component.
