摘要：
A method for performing a procedure in a body lumen and/or body cavity,said method including: providing apparatus including: a sleeve adapted to beslidover the exterior of an endoscope； an aft balloon secured to the sleeve； aninflation/deflation tube carried by the sleeve and in fluid communication withtheinterior of the aft balloon； a pair of hollow push tubes slidably mounted tothesleeve, the pair of hollow push tubes being connected to one another at theirdistalends with a raised push tube bridge, the raised push tube bridge beingconfiguredto nest an endoscope therein； and a fore balloon secured to the distal ends ofthepair of hollow push tubes, the interior of the fore balloon being in fluidcommunication with the interiors of the pair of hollow push tubes, wherein thefore balloon is capable of assuming a deflated condition and an inflatedcondition,and further wherein (i) when the fore balloon is in its deflated condition, anaxialopening extends therethrough, the axial opening being sized to receive theendoscope therein, and (ii) when the fore balloon is in its inflatedcondition, theaxial opening is closed down； positioning the apparatus in the body lumenand/orbody cavity； inflating the aft balloon； advancing the push tube distally；inflatingthe fore balloon； and performing the procedure.
