Abstract
Abstract A device for managing urinary incontinence in a human female includes a resilient body resilient adapted to fit between the labia minora and the floor of the vestibule of the vulva, thereby occluding the urethral meatus. An adhesive is applied to the body to provide a sealing engagement with the urethral meatus. In a first embodiment, the body has a base that seats against the floor of the vestibule, and a pair of flexible, lateral flaps that engage the labia minora. A layer of adhesive is applied to the base. A layer of highly-absorbant, hydrophilic material may be situated between the base and the adhesive layer, and/or a layer of scrim material may be so situated. The body may have a longitudinal ridge with a posterior edge having a finger hole to facilitate installation and removal of the device. In a second embodiment, the body is substantially tubular, with the adhesive applied to the exterior surface of the body. In the first and second embodiments, the body is preferably formed of a biodegradable material. In a third embodiment, the body is a flexible bladder or sac, filled with a suitable liquid or gel, that conformingly fits between the labia minora and the floor of the vestibule so as to occlude the urethral meatus. The exterior surface of the bladder is coated with an adhesive to provide a sealing engagement with the meatus. In all embodiments, the preferred adhesive is a mixture of poly 2-hydroxyethyl methacrylate and polyethylene glycol.
