Patent ID: 8231658

Claim:
An introducer device for a thermal ablation system, comprising: a housing including a housing lumen sized and shaped to slidably receive a visualization device therein, the housing further including a slot extending therethrough from an interior surface defining the housing lumen to an exterior surface thereof, the slot sized to receive therein a projection extending from a visualization device received in the housing lumen radially away from the housing lumen and past the exterior surface of the housing; a sheath extending distally from a handle, the sheath being sized and shaped for insertion through a natural body opening into a hollow body organ, the sheath including a fluid delivery lumen delivering heated fluid to the organ and a fluid return lumen withdrawing the fluid after it has been circulated through the organ; a connector including a connector lumen aligned with the housing lumen and sized and shaped to slidably receive therein the visualization device; a locking arrangement movably coupled to the housing, movement of the locking arrangement relative to the housing opening and closing the slot; and an adjustment mechanism moving the connector relative to the housing to adjust a distance between a proximal end of the connector lumen and a distal end of the sheath.
