An endocervical seal has a sleeve with a passageway for receiving an intrauterine interventional or diagnostic tool. The sleeve has a coaxially disposed outer balloon with a distal portion configured to inflate in a cervical os and a proximal portion configured to inflate in a cervical canal.
Claims5
A method of using an endometrial ablation system, comprising
- positioning a seal assembly in an endocervical canal with a distal seal end proximate an internal os;
- introducing a probe shaft through a central passage in the seal assembly into a uterine cavity;
- expanding a distal expandable-collapsible energy-delivery surface carried by the probe shaft so that the expanded surface contacts a wall of the uterine cavity;
- observing the axial relationship between the seal assembly and probe shaft to check system parameters against measurements of the endocervical canal and uterine cavity;
- and
- delivering energy through the energy-delivery surface into the wall of the uterine cavity.
