Abstract
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 Analysis
Total Claims: 9
Claim 1
Independent Claim
173 words
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.
Claim 2
Independent Claim
173 words
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.
Claim 3
Dependent Claim
29 words
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.
Claim 4
Dependent Claim
34 words
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.
Claim 5
Dependent Claim
25 words
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.
