The liner may be intentionally sized to be substantially larger than the typical size of the uterine cavity, e.g., 1.2 times (or more), greater than the size of the uterine cavity into which the liner is inserted. Because the liner is sized intentionally larger than the body lumen to be treated, the liner may never fully expand when deployed. But even with folds or portions of the liner being folded upon itself, the liner may remain 10 sufficiently supple such that the resulting uncontrolled folds allow for complete conformance of the liner against the anatomy of the contacted tissue.6/6 UT 80 20" 205 20'T 12 12 12 FIG. 5A FIG. 5B FIG. 5C 80 20" 80 FIG. 5D
