ABSTRACT:
An expandable multifunctional instrument for performing various diverse operative procedures includes an elongate distensible member having a distal end for being introduced in an anatomical cavity via a relatively small size anatomical opening and being movable from a non-distended position facilitating introduction through the anatomical opening to a distended position wherein the cross-sectional size of the distensible member is increased and a plurality of collars disposed on portions of the distensible member for constraining movement of the distensible member portions to the distended position. The collars are movably mounted on the distensible member for adjusting the location and size of unconstrained distensible portions of the distensible member adjacent the collars. A method of performing an operative procedure in an anatomical cavity includes the steps of introducing a distal end of an elongate distensible member in the anatomical cavity through a relatively small size anatomical opening with the distensible member in a non-distended position, moving the distensible member from the non-distended position to a distended position and constraining selected portions of the distensible member against movement to the distended position to selectively contour the distensible member in the distended position to have a plurality of protuberances.
