An expandable multifunctional instrument (10) for creating a space at an obstructed site in the body includes an elongate member (12) having a distal end (20) for being introduced in the body, a proximal end for being disposed externally of the body, and an expandable member (16) for being positioned at the obstructed site. The expandable member (16) is movable at the obstructed site from a non-expanded position to an expanded position to displace anatomical tissue to create a space at the obstructed site for performing various operative procedures. A method of creating a space at an obstructed site includes expanding an expandable member (16) at the obstructed site, and/or introducing fluid under pressure at the obstructed site to create a space where normally no space exists. |
