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 endoscopic procedures in an anatomical cavity comprising the steps of

inserting a sleeve through a wall of the anatomical cavity for insertion of instruments into the anatomical cavity;

providing a balloon within the anatomical cavity; and

manipulating organ structures within the anatomical cavity using the balloon.

2. A method of performing endoscopic procedures as recited in claim 1 wherein the balloon is carried by a member extending through the sleeve and said manipulating step includes moving the member externally of the anatomical cavity.

3. A method of performing endoscopic procedures as recited in claim 1 wherein said manipulating step includes separating organ structures.

4. A method of performing endoscopic procedures as recited in claim 1 wherein said manipulating step includes separating the anatomical cavity wall from organ structures within the anatomical cavity.

5. A method of performing endoscopic procedures as recited in claim 1 wherein said manipulating step includes elevating one organ structure relative to another organ structure.

6. A method of performing endoscopic procedures as recited in claim 1 and further comprising, prior to said manipulating step, the step of inflating the balloon.

7. A method of performing endoscopic procedures as recited in claim 1 wherein said manipulating step includes inflating the balloon.

8. 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;

constraining the selected portions of the distensible member with the collars to prevent movement of the selected portions to the distended position to selectively contour the distensible member to have a plurality of 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.

10. A method of performing an operative procedure as recited in claim 9 wherein said step of constraining further includes adjusting the position of

the collar on the distensible member to adjust the contour of the distensible member in the distended position.

11. A method of performing an operative procedure as recited in claim 10 wherein said step of moving includes supplying fluid to the distensible member to distend the distensible member.

12. A method of performing an operative procedure as recited in claim 11 wherein said step of supplying fluid includes contacting body fluid with the distensible member for absorption by the distensible member.

13. 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 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 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, said step of performing including collecting anatomical cell samples with the distensible member.

14. 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, the multifunctional medical instrument having a longitudinal axis;

positioning the distensible member distal end at an angle to the longitudinal axis subsequent to introduction in the anatomical cavity;

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 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 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.
