Expandable multifunctional manipulating instruments for various medical procedures and methods therefor
First Claim
1. A multifunctional instrument for performing various medical procedures at an internal operative site in a body comprisingan elongate expandable member having a distal end for being introduced at the operative site through a relatively small size opening in the body, a proximal end for being held externally of the body and a lumen between said distal and proximal ends, said expandable member including a balloon having a preformed predetermined shape, said balloon being movable between a non-expanded position wherein said balloon has a first cross-sectional size to facilitate introduction at the operative site through the opening and an expanded position wherein said balloon has a second cross-sectional size larger than said first cross-sectional size;
- a plurality of outer members for being disposed over respective portions of said balloon, said outer members constraining said respective portions against movement to said expanded position whereby said balloon adjacent said portions forms a plurality of protuberances when said balloon is moved from said non-expanded position to said expanded position, said outer members being movable longitudinally along said balloon to vary the locations of said portions; and
a fluid supply system coupled with said balloon for supplying fluid to said balloon to move said balloon from said non-expanded position to said expanded position.

Abstract
An expandable multifunctional instrument for performing various diverse operative procedures includes an elongate distensible member having a distal end for being introduced in an anatomical cavity via a relatively small size anatomical opening and being movable from a non-distended position facilitating introduction through the anatomical opening to a distended position wherein the cross-sectional size of the distensible member is increased and a plurality of collars disposed on portions of the distensible member for constraining movement of the distensible member portions to the distended position. The collars are movably mounted on the distensible member for adjusting the location and size of unconstrained distensible portions of the distensible member adjacent the collars. A method of performing an operative procedure in an anatomical cavity includes the steps of introducing a distal end of an elongate distensible member in the anatomical cavity through a relatively small size anatomical opening with the distensible member in a non-distended position, moving the distensible member from the non-distended position to a distended position and constraining selected portions of the distensible member against movement to the distended position to selectively contour the distensible member in the distended position to have a plurality of protuberances.

11. A multifunctional instrument for performing various medical procedures in an anatomical cavity comprising
an elongate balloon having a distal end for being introduced in the anatomical cavity through a relatively small size opening in a wall of the anatomical cavity, a proximal end for being held externally of the anatomical cavity and a lumen between said distal and proximal ends; - an inner member disposed in said lumen and forming a seal with said balloon at said distal end of said balloon, said balloon being movable between a non-expanded position wherein said balloon has a first cross-sectional size to facilitate introduction in the anatomical cavity through the opening and an expanded position wherein said balloon has a second cross-sectional size larger than said first cross-sectional size;
a fluid supply system coupled with said lumen for supplying fluid between said balloon and said inner member to expand said balloon to move said balloon from said non-expanded position to said expanded position; an outer member for being disposed over a portion of said balloon, said outer member constraining said portion against movement to said expanded position whereby said balloon adjacent said portion forms a protuberance when said balloon is moved to said expanded position, said outer member being movable along said balloon to vary the location of said portion; and a handle mounting said proximal end of said balloon, said handle having a shape corresponding to the shape of the anatomical cavity.
- an inner member disposed in said lumen and forming a seal with said balloon at said distal end of said balloon, said balloon being movable between a non-expanded position wherein said balloon has a first cross-sectional size to facilitate introduction in the anatomical cavity through the opening and an expanded position wherein said balloon has a second cross-sectional size larger than said first cross-sectional size;
