Abstract: Hysteroscopic system includes a hysteroscope having a main body coupled to an extension portion. 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.

Abstract: A system for treating uterine tissue having a seal assembly configured for positioning in a patient's cervical canal and uterine cavity; an expandable distal balloon portion; an expandable elongate medial balloon portion configured for movement between a first transversely expanded shape for engaging a cervical canal and a second transversely non-expanded shape for trans-cervical insertion; and a fluid source in communication with distal balloon portion and medial balloon portion for expansion of said balloon portions.

Abstract: A wall of a uterus is ablated by expanding a structure in the uterus and applying energy across the wall of the structure into the uterine wall. An exterior surface of the structure conforms to an inner wall of the uterus, and the energy may cause vapor to collect between the wall and the structure. The vapor is released by providing a barrier to release which is inflated at a pressure above which the barrier at least partially collapses to allow the vapor to leave the uterus.

Abstract: Tissue may be cut and extracted from an interior location in a patient's body using a probe or tool which both effects cutting and causes vaporization of a liquid or other fluid to propel the cut tissue through an extraction lumen of the cutting device. The cutting may be achieved using an electrosurgical electrode assembly, including a first electrode on a cutting member and a second electrode within a cutting probe or tool.

Abstract: Methods, systems and devices for evaluating the integrity of a uterine cavity. A method comprises introducing transcervically a probe into a patient's uterine cavity, providing a flow of a fluid (e.g., CO2) through the probe into the uterine cavity and monitoring the rate of the flow to characterize the uterine cavity as perforated or non-perforated based on a change in the flow rate.
