20 Claims

1. A medical device, comprising:

a handle including a handle lumen extending therethrough;

a first body shaft including a first body shaft lumen in direct communication with the handle lumen;

a radio frequency (RF) electrode tip positioned at a distal end of the first body shaft, wherein the RF electrode tip includes a lumen extending therethrough and in direct communication with the lumen of the first body shaft; and

an energy delivery wire electrically coupled with the RF electrode tip,

wherein the RF electrode tip is a ceramic tip, and

wherein a laser fiber is positioned within the first body shaft lumen and the laser fiber is configured to extend distally to cauterize tissue and retract proximally relative to the RF electrode tip, the laser fiber being thermally protected from the RF electrode tip when retracted within the lumen.
