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.

Claims

1. A method of performing an operative procedure in an anatomical cavity comprising the steps of

introducing a distal end of a distensible member of a multifunctional medical instrument in the anatomical cavity through a relatively small size opening in a wall of the anatomical cavity with the distensible member in a non-distended position facilitating introduction of the distensible member through the opening;

moving the distensible member from the non-distended position to a distended position to increase the cross-sectional size of the distensible member between the distal end and a proximal end of the distensible member;

constraining selected longitudinally spaced portions of the distensible member between the distal and proximal ends to prevent movement of the selected portions to the distended position to selectively contour the distensible member to have a plurality of longitudinally spaced protuberances for engaging anatomical tissue in accordance with the operative procedure to be performed; and

performing an operative procedure in the anatomical cavity with the multifunctional instrument with the distensible member in the distended position.

2. A method of performing an operative procedure as recited in claim 1 wherein said step of performing includes introducing medical instruments in the anatomical cavity through the distensible member.

3. A method of performing an operative procedure as recited in claim 2 and further including stabilizing the multifunctional instrument relative to the anatomical cavity with the distensible member in the distended position to stabilize instruments introduced through the lumen.

4. A method of performing an operative procedure as recited in claim 1 wherein said step of performing includes manipulating anatomical tissue with the distensible member in the distended position.

5. A method of performing an operative procedure as recited in claim 1 wherein said step of performing includes separating adhering tissue with the distensible member in the distended position.

6. A method of performing an operating procedure as recited in claim 1 wherein the distensible member includes a balloon and said moving step includes inflating the balloon.
