  • Patent number: 11944763
    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.

  • Publication number: 20230225897
    Abstract: Fecal management methods and apparatuses (e.g., devices, systems, etc.) are described herein. The fecal management apparatuses may apply one or more fecal removal cycles of suction and irrigation (and in some examples air) to actively remove fecal material. The apparatus may control the timing of delivery of the fecal removal cycles as well as the parameters of the applied suction, irrigation and/or air within and between fecal removal cycles.

  • Publication number: 20230190510
    Abstract: A urine removal device includes a pouch with a proximal opening that provides access to an internal compartment of the pouch that is suitable to contain urine. A fluid diverter system is disposed inside of the pouch and extends from the proximal portion of the pouch, where it interfaces via an outlet conduit member to the environment outside of the pouch, to the distal end of the pouch where it draws in urine from the pouch. The pouch has at least one air port to allow air flow through the device to support suction that is applied inside of the pouch. The fluid diverter system has at least one conduit member configured to draw urine from the distal portion of the pouch up to the proximal end of the pouch, and into the outlet conduit member where it exits the fluid collection device.

  • Publication number: 20230020563
    Abstract: The invention comprises a urine removal devices that enable urine discharged from a male patient's penis to be contained within a flexible pouch and drawn out of the pouch and away from the genital region of the patient through a drain tube. The pouch comprises a first fluid compartment, a second fluid compartment and a fluid transmission passageway connecting the first fluid compartment and the second fluid compartment—wherein the fluid transmission passageway comprises a thin-film unidirectional fluid flow valve configured to enable for fluid flow from the first fluid compartment to the second fluid compartment, and to prevent fluid flow from the second fluid compartment to the first fluid compartment. The pouch may have an aperture sized to permit a male patient's penis to enter the pouch within the first fluid compartment.

  • Patent number: 8926620
    Abstract: In some embodiments, an apparatus includes an elongated member, an expandable member coupled to the elongated member, and an outer sheath. The outer sheath, which can be constructed from a different material than the expandable member, is disposed about the expandable member such that an outer surface of the expandable member is in discontinuous contact with an inner surface of the outer sheath. The expandable member and the outer sheath are configured to cooperatively displace a bone structure when moving between a collapsed configuration and an expanded configuration.
