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.

Claims

1. A method of creating an operating space endoscopically at an obstructed site in anatomical tissue of a body including the steps of

introducing in the anatomical tissue an expandable multifunctional instrument including an elongate outer member carrying a first expandable member disposed in a non-expanded position and an elongate inner tubular member disposed in the outer member and carrying a second expandable member disposed in a non-expanded position and spaced from the first expandable member with a second instrument extending through the inner tubular member to locate a distal end of the second instrument and the first and second expandable members at the obstructed site, the distal end of the second instrument being disposed externally, distally of a distal end of the inner tubular member during said step of introducing;

moving the first and second expandable members from the non-expanded positions to expanded positions, respectively, to displace the anatomical tissue to create a space at the obstructed site; and

visually confirming creation of the space with an endoscope from externally of the body.

2. The method as recited in claim 1 and further including, prior to said step of moving, the step of adjusting the spacing between the first and second expandable members.

3. The method as recited in claim 2 wherein said step of adjusting includes moving at least one of the inner and outer members longitudinally relative to the other of the inner and outer members.

4. The method as recited in claim 1 wherein said step of moving includes expanding the first and second expandable members to different external sizes, respectively.

5. A method of creating an operating space endoscopically at an obstructed site in anatomical tissue of a body including the steps of

introducing in the anatomical tissue an expandable multifunctional instrument including an elongate outer member carrying a first expandable member disposed in a non-expanded position and an elongate inner tubular member disposed in the outer member and carrying a second expandable member disposed in a non-expanded position and spaced from the first expandable member with a second instrument extending through the inner tubular member to locate a distal end of the second instrument and the first and second expandable members at the obstructed site, the second instrument being a penetrating instrument and said step of introducing including penetrating the anatomical tissue with the distal end of the second instrument;

moving the first and second expandable members from the non-expanded positions to expanded positions, respectively, to displace the anatomical tissue to create a space at the obstructed site; and

visually confirming creation of the space with an endoscope from externally of the body.

6. A method of creating an operating space endoscopically at an obstructed site in anatomical tissue of a body including the steps of

introducing in the anatomical tissue an expandable multifunctional instrument including an elongate outer member carrying a first expandable member disposed in a non-expanded position and an elongate inner tubular member disposed in the outer member and carrying a second expandable member disposed in a non-expanded position and spaced from the first expandable member with a second instrument extending through the inner tubular member to locate a distal end of the second instrument and the first and second expandable members at the obstructed site;

moving the first and second expandable members from the non-expanded positions to expanded positions, respectively, to displace the anatomical tissue to create a space at the obstructed site;

withdrawing the second instrument from the inner tubular member subsequent to said step of moving; and

visually confirming creation of the space with an endoscope from externally of the body.
