Abstract:
A method of treating polyps of a patient, the method comprising:(a) directing a medical device to the polyps site of the patient, wherein the device has a distal section, a distal end, a proximal end, a lumen extending therebetween, a handle attached to the proximal end of the device, electrode means for providing energy to a tissue disposed at the distal end, energy means for providing energy through a conducting wire to said electrode means, means for generating rotational vibration at the distal section located within the handle, wherein the means for generating rotational vibration at the distal section comprises a motor mounted in a cavity of the handle, which has a rotatable motor shaft, an elongated connecting shaft having a first end to which the electrode means is connected, and a second end connected to the handle, a weight eccentrically mounted onto the motor shaft, with respect to the motor shaft axis, so as to rotate eccentrically, so that when the motor shaft rotates, the electrode means vibrates;(b) contacting the electrode means of the device against the polyps site of a patient;(c) applying RF energy through said energy means to the electrode means of the medical device to effect heat treatment of the polyps; and(d) starting rotational vibration to the distal section of the device to effect a vibrational massage therapy to the polyps site.
