Intrauterine treatment device with articulating array

An intrauterine ablation device, comprising:

• a sheath;
• an articulating array disposed within the sheath and including a plurality of expansion chambers to provide an insertion geometry of the articulating array when the plurality of expansion chambers are in a non-expanded position, and to provide an installed geometry of the articulating array when the plurality of expansion chambers are in an expanded position;
• wherein the articulating array is configured to extend from the sheath and to retain the insertion geometry with the plurality of expansion chambers in the non-expanded position;
• and
• wherein the plurality of expansion chambers are configured to expand to transition to the installed geometry placing an outer surface of the articulating array proximate to a uterine lining of a patient.

A method for facilitating ablation of a uterine tissue, the method comprising:

• providing an articulating array disposed within a sheath having a plurality of adjacent expansion chambers arranged in a linear arrangement, the articulating array having an insertion geometry with the plurality of expansion chambers in a non-expanded position and having an installed geometry with the plurality of expansion chambers in an expanded position;
• advancing the sheath and articulating array in the insertion geometry through a cervical canal and into a uterus of a patient;
• extending the articulating array from the sheath while maintaining the plurality of expansion chambers in the insertion geometry;
• expanding the plurality of expansion chambers to an expanded position so as to transition the articulating array and the conductive array between the insertion geometry and the installed geometry;
• and
• executing an ablation operation so as to ablate a uterine surface of the patient with the articulating array in the installed geometry.
