Abstract
A treatment apparatus includes a cannula with a cannula lumen. The cannula has a first average diameter. A probe is positionable in the cannula lumen. The probe has a first section with a second average diameter and a second section with a third average diameter that is less than the second average diameter. At least a portion of the second section has a curved section with at least one radius of curvature. The radius of curvative is selected to provide that as the second section passes through the cannula lumen a first side of the second section is tangential to a first side of the cannula lumen, and a second opposing side of the second section is tangential to a second opposing side of the cannula lumen.
