Claim 13:
14. A medical device, comprising:
a device shaft, including a distal end and a device shaft lumen;
an electrode shaft configured to deliver energy to a treatment site, wherein the electrode shaft includes an electrode shaft lumen configured to deliver fluid to the treatment site, wherein the electrode shaft is coupled to and longitudinally movable relative to the device shaft, and wherein the electrode shaft lumen is fluidly connected to the device shaft lumen; and
an insulation tip coupled to a distal tip of the electrode shaft,
wherein the insulation tip includes an insulation tip lumen fluidly connected to the electrode shaft lumen and configured to deliver fluid to the treatment site,
wherein the insulation tip covers an entirety of the distal tip of the electrode shaft,
wherein the insulation tip includes a rounded distal end and a cylindrical side portion,
wherein the rounded distal end is hemispherical and extends distally beyond the distal tip of the electrode shaft,
wherein the insulation tip lumen includes a wide portion configured to receive a portion of the distal tip of the electrode shaft and a narrow portion extending distally beyond the distal tip of the electrode shaft, and
wherein the narrow portion of the insulation tip lumen includes a cross-sectional width equal to a cross-sectional width of the electrode shaft lumen, wherein the narrow portion includes a distal end portion that includes a chamfer.
