Fundus bumper mechanical reference for easier mechanism deployment

An intrauterine ablation device, comprising:

• a central support member;
• and
• an energy applicator operatively coupled to a distal end portion of the central support member, the energy applicator comprising
• a first flexure coupled to a distal end portion of the central support member, the first flexure having a first flexure distal free end,
• a second flexure coupled to the distal end portion of the central support member, the second flexure having a second flexure distal free end, wherein the first and second flexures are adjustable between a collapsed configuration, in which the first and second flexure distal free ends are closely apposed to one another so that the energy applicator is configured for transcervical introduction into a uterus, and an expanded configuration, in which the first and second flexure distal free ends extend laterally away from one another in opposite directions,
• a flexible tissue contacting member overlaying the first and second flexures and configured for delivering ablative energy to an endometrial lining of the uterus, and
• a distal bumper coupled to the tissue contacting member and configured to prevent the first and second flexure distal free ends from engaging a fundal wall of the uterus during a transition of the first and second flexures from the collapsed configuration to the expanded configuration.
