Embodiment Construction

[0055][0054] Referring to FIG. 1 , a first exemplary system 10 constructed in accordance with the principles of the present invention includes a bipolar electrode probe 12 and a radio frequency (RF) electrosurgical power source 14 . Bipolar electrode probe 12 includes a flexible shaft 16 having a distal end 18 and a proximal end 20 with a Y-connector sleeve 22 attached thereto. A first electrode 24 and a second electrode 26 are mounted on the shaft 16 near the distal end 18 . The shaft 16 has a central lumen that extends along the entire length of the shaft (from the proximal end to the distal tip), and this lumen can generally be connected by a flexible wire 30 via a luer connector (not shown), the flexible The line 30 has a luer connector or other connector sleeve 32 at its other end, which end can be connected to a source of infusion fluid, typically saline. Electrodes 24 and 26 may be connected to RF electrosurgical power source 14 via cable 34 and connector 36 . The con...

Abstract

An energy delivering probe (12) 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 (12) includes a shaft (16) and one, or two, or more electrodes (24, 26) where at least one of the electrodes has a perimeter that increases as it extends proximally. In an embodiment, the shaft comprises a sharp distal tip configured to puncture body tissue and the sharp tip is preferably integrally formed with the distal electrode.

Description

technical field [0001] [0001] The present invention generally relates to medical methods and devices. More specifically, the present invention relates to the design and use of energy delivery probes for thermally coagulating and / or shrinking hollow anatomical structures (HAS) including blood vessels such as veins that: superficial Perforator veins that connect veins to deep veins, main superficial veins of the legs (eg, great saphenous vein, small saphenous vein, and similar veins), superficial branch veins of the legs, internal spermatic veins (the spermatic veins varices), ovarian veins, gonadal veins, rectal canal, fallopian tubes, arteriovenous malformations, arteriovenous fistula collaterals, esophageal varices, and similar veins. In addition, the probe can be used to thermally coagulate tissue, such as breast cancer tissue or liver tissue. For purposes of illustration, a representative description will be given of the apparatus and method of the present invention for t...
