Abstract: Devices for preventing and/or otherwise inhibiting biofilm formation include a lumen and/or a cavity coupled with a wall configured for holding oils, which leach through the wall of the devices to a surface, the oils at the surface creating a smooth surface coating.

Abstract: The invention provides a system treating a weak or leaking urinary or other sphincter. The system includes two magnets and one or more devices to immobilize one of the magnets on a first side of the body organ to immobilize the other magnet on the second side of the body organ. The magnets may be positioned around the body organ with opposite poles facing each other. The invention may be used to induce the formation of muscle tissue of a sphincter such as a urethral sphincter or gastroesophageal sphincter, and also for mechanically occluding a leaking urethral or vesicovaginal fistula.

Abstract: The invention provides medical device for insertion into a body cavity such as the urinary bladder, and for the release of substances into the cavity. The device includes a core and an expandable balloon surrounding the core. The balloon wall is made from an elastic permeable material. When the balloon is empty, the balloon wall is stretched and applied to a surface of the core. A valve allows introductions of one or more fluids between the wall of the balloon and the surface of the core. The invention also provides a system including the device of the invention and one or more instruments for inserting the device into the body cavity or retrieving the device from the body cavity.
