Abstract
A retention device for use in a human or mammalian body includes superelastic wires that expand when they are released from a confined state. The retention device may have the outer form of a Foley catheter. One or more superelastic wires within the balloon of a Foley catheter help to insure retention within the body, such as within a urinary bladder.
