1. A method of treating a perforator vein comprising:
- achieving direct percutaneous access into tissue with a rigid stylet having a resistive heating coil, at least one electrode forming a portion of an exterior surface of the stylet, and a sharp tip and without the use of an introducer sheath, the resistive heating coil being covered by an electrically insulative sleeve;
advancing the stylet to the perforator vein; and
occluding the perforator vein by applying energy from the resistive heating coil to the perforator vein.

Abstract
An energy delivering probe is used for thermally coagulating and/or constricting hollow anatomical structures (HAS) including, but not limited to, blood vessels such as perforator veins. The probe includes a shaft and an energy source.

12. A method comprising:
-
directly accessing a target site with a rigid probe through the skin, the target site being within or near a perforator vein, the rigid probe comprising; a tapered resistive heating coil on an outside surface of and near a distal end of the probe; at least one electrode on the outside surface of the probe adjacent the resistive heating coil; a nonconductive sleeve on an outside surface of the resistive heating coil; and a sharp tip at a distal end of the probe and configured to penetrate tissue; applying heat energy from the resistive heating coil to the perforator vein with the probe; and constricting a region of the perforator vein. - View Dependent Claims (13, 14, 15, 16)

17. A method comprising:
-
achieving direct access with a rigid probe through the skin to a target site within or near a perforator vein, the rigid probe comprising; a sharp tip at a distal end of the probe and configured to penetrate tissue; a resistive heating coil proximal of the sharp tip, the resistive heating coil being covered by an electrically insulative sleeve; and at least one electrode adjacent the resistive heating coil, the at least one electrode being configured to contact the perforator vein; retracting the sharp tip within the probe; applying energy to the perforator vein with the probe resistive heating coil; and constricting a region of the perforator vein. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24)
