The extension portion may be a shaft configured to extend transcervically to a patient' s uterine cavity. Firt, 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 6/23 PCT/US2013/022559 I IN Hr l Ien 0 It 0 ii I I Ln I' LL LI - - -- - - -
