## Abstract

Apparatus for endoscopically retracting tissue, the apparatus comprising a sleeve adapted to be slid over the exterior of an endoscope; a balloon movably mounted to the sleeve; and at least one connector extending from the balloon and configured to be secured to tissue which is to be retracted; wherein the balloon is configured to be moved relative to the sleeve in order to retract the tissue.

## Claims

### Claim 1

Apparatus comprising:
a sleeve adapted to be slid over the exterior of an endoscope, wherein the endoscope comprises a proximal end and a distal end, and a handle disposed at the proximal end of the endoscope, and wherein the sleeve comprises a proximal end, a distal end and a sleeve lumen extending therebetween, and further wherein the sleeve is configured to be slid over the exterior of the endoscope so as to substantially cover the exterior of the endoscope from a point adjacent to the distal end of the endoscope to a point adjacent to the handle of the endoscope;
a balloon secured to the sleeve adjacent to the distal end of the sleeve;
a pair of push tubes extending from the distal end of the sleeve to the proximal end of the sleeve; and
at least one instrument lumen carried by the sleeve, wherein the at least one instrument lumen comprises a proximal end, a distal end and a lumen extending therebetween, wherein the distal end of the instrument lumen opens at the distal end of the sleeve, distal to the balloon, whereby to facilitate advancement of a tool to the distal end of the sleeve such that the tool exits the sleeve distal to the balloon.

### Claim 2 (depends on 1)

Apparatus according to claim 1 wherein the sleeve is flexible.

### Claim 3 (depends on 1)

Apparatus according to claim 1 wherein the sleeve lumen has a central axis, wherein the instrument lumen has a central axis, and further wherein the central axis of the instrument lumen is in fixed relation to the central axis of the sleeve lumen.

### Claim 4 (depends on 1)

Apparatus according to claim 1 wherein the at least one instrument lumen is disposed external to the sleeve lumen.

### Claim 5 (depends on 1)

Apparatus according to claim 1 further comprising:
an inflation/deflation tube carried by the sleeve and in fluid communication with an interior of the balloon.

### Claim 6 (depends on 1)

Apparatus according to claim 1 wherein the pair of push tubes are slidably mounted to the sleeve.

### Claim 7 (depends on 6)

Apparatus according to claim 6 further comprising a pair of passageways mounted to the sleeve, and further wherein the pair of push tubes are slidably mounted within the pair of passageways.

### Claim 8 (depends on 1)

Apparatus according to claim 1 wherein the sleeve lumen has a central axis, wherein the pair of push tubes each have a central axis, and further wherein the central axes of the pair of push tubes are in fixed relation to the central axis of the sleeve lumen.
