Abstract
An expandable multifunctional instrument for creating a space at an obstructed site in anatomical tissue in the body including an elongate member having a distal end for being positioned at the obstructed site, a proximal end for being disposed externally of the body and an expandable member at the distal end of the elongate member. The expandable member includes a balloon movable fluidically from a non-expanded position to an expanded position at the obstructed site. The balloon assumes a preformed, predetermined configuration in the expanded position at the obstructed site to separate the anatomical tissue to create a space at the obstructed site.
