Abstract:
1. A method for minimally invasive treatment of uterine fibroids, said method comprising: introducing a sheath into a uterus having a uterine wall; determining a location of a fibroid using a visualization element within or on the sheath; steering a portion of the sheath to position at least two treatment needles at the determined location above the uterine wall; deploying said at least two treatment needles from a side of the sheath through the uterine wall and into uterine tissue at spaced-apart locations on the uterine wall such that the needles converge or diverge from said spaced-apart wall locations as they enter the tissue so that said needles anchor in the tissue; treating the fibroid with the needles while the needles remain anchored and substantially immobile; and withdrawing the needles entirely back into the sheath when the treatment is complete.
