DEVICE FOR ENDOMETRIAL ABLATION HAVING AN EXPANDABLE SEAL FOR A CERVICAL CANAL

摘要

Methods, systems and devices for endometrial ablation. In accordance with a method, a working end of an RF ablation device is positioned in a patient uterus to contact endometrial tissue, the working end comprising a dielectric wall capable of non-expanded and expanded shapes and for conforming to an asymmetric or symmetric shape of the patient's cervix. An expandable seal is provided for sealing the cervical canal.

主权项

1. A method for treating uterine tissue, said method comprising:
introducing a member having first and second concentric sleeves through a cervical canal and into a uterine cavity of a patient while a deformable thin-wall seal carried by the sleeves is stretched tight against the introducer member by distally extending the second concentric sleeve relative to the first concentric sleeve; axially translating the first concentric sleeve relative to the second concentric sleeve to cause the deformable thin-wall seal to transition to a transversely expanded shape having a first transverse dimension to engage the cervical canal; and inflating the expanded seal to an second transverse dimension greater than the first transverse dimension which resulted from movement of the sleeves while the expanded seal engages the cervical canal.
