Abstract
An expandable multifunctional instrument for creating a space at an obstructed site in the body includes an elongate member having a distal end for being introduced in the body, a proximal end for being disposed externally of the body and an expandable member for being positioned at the obstructed site. The expandable member 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 at the obstructed site and/or introducing fluid under pressure at the obstructed site to create a space where normally no space exists.
