Date Sep. 12, 1996Apparatus for dilating a body cavity comprising at least two elongate elements positioned in generally side-by-side relationship. The elongate elements are movable laterally with respect to each other between a contracted condition wherein first end sections of the elongate elements are closely adjacent one another for insertion into the body cavity, and an expanded condition wherein the first end sections of the elongate elements are circumferentially spaced apart for dilating the body cavity. The elongate elements are arranged to normally occupy the contracted condition, and a control device is provided for selectively moving the elongate elements from the contracted condition to the expanded condition.
