The extension portion may be a shaft configured to extend transcervically to a patient's uterine cavity. First, second, and third channels extend from the main body to a distal end of the extension portion. A fluid source is coupleable to a proximal end of the first channel, and a pressure sensor is coupleable to a proximal end of the second channel. A tissue resecting probe is configured for introduction through the third channel. At least one resistance feature is included which is configured to provide a selected level of resistance to axial sliding of the probe through the third channel while permitting rotation of the probe within the third channel.WO 2013/110073 1/23 PCT/US2013/022559 145 140 102 105 50 138 L IG HT SOURCE 136: - - - - - - -- 10 110a FLUID INFLOW SOURCE 120 104 132 10 162 140 164 e CONTROLLER 155 CAMERA 166 135 1007 156 r RFSOURCE 15 I 142NEGATIVE PRESSURE 165 1SOURCE 125 FIG. 1 159 11 158 _ .__ 1 L - ------ - ------ --
