Abstract: A method and system for providing remote or automatic release of a leash is disclosed. The release of the leash can be triggered by a remote user control, by a predetermined distance between the user and what is connected to the leash, or by various other means or events. The leash can be selectively released from a latch mechanism, from an integrally-attached spool housing, and the like.

Abstract: This document provides methods and materials related to ostomy devices. For example, ostomy bags or pouches that can be used to collect discharge from a temporary or permanent ostomy opening are provided.

Abstract: This document provides methods and materials related to ostomy devices. For example, methods and materials that can be used to prevent waste material and/or gas from escaping a waste reservoir of an ostomy patient such as ostomy plug devices configured to include a sealing element, a tensioning element, and a cap element are provided.

Abstract: A self propelled, endoscopic apparatus formed of a flexible, fluid-filled toroid and a motorized or powerable frame The apparatus may be used to advance a variety of accessory devices into generally tubular spaces and environments for medical and non-medical applications. The apparatus when inserted into a tubular space or environment, such as the colon of a patient undergoing a colonoscopy, is advanced by the motion of the toroid. The toroid's surface circulates around itself in a continuous motion from inside its central cavity along its central axis to the outside where its surface travels in the opposite direction until it again rotates into its central cavity. As the device advances within the varying sizes, shapes and contours of body lumens, the toroid compresses and expands to accommodate and navigate the environment. The motion of the toroid can be powered or unpowered and the direction and speed may be controlled.

Abstract: An apparatus includes a self-enclosed tube, sized and shaped to fit within and engage a human or animal body cavity, the tube comprising an inner surface defining an enclosed region and an outer surface that turns outward to engage the body cavity and turns inward to encompass a central region defining a concentric longitudinal path, wherein the tube is powerable to provide relative movement of the tube relative to the cavity in at least one of a forward or reverse direction with respect to the longitudinal path, and a compressible structure, configured to bias the outer surface of the tube outward to engage the body cavity at a first outer diameter, the compressible structure being deformable inward in response to a compressive force to provide a second outer diameter that is less than the first outer diameter.
