Abstract
An electrode for use in an electrosurgical procedure for treating entropion by excising a wedge-shaped portion of the tarsus at the underside of a patient's eyelid. In a preferred embodiment, the electrode is uniquely configured to form a diamond-shaped support terminating in an active wire, generally V-shaped, whose width controls the width of the excised wedge, and the length of whose arms controls the thickness of the excised wedge. The active wire is supported by structure that is completely electrically-insulated to ensure excision only of the desired tissue while avoiding damage to surrounding tissue. The tissue incising is effected with the bare active wire at a depth stopped by a shoulder between the bare wire arms and the adjacent portions of the electrode support.
