Abstract
Abstract An ablation device for treating canker sores or reducing the mass of cellular tissue, wherein an elongated tubular element includes at least one electrode disposed at its distal section, RF energy generating means, and means for generating vibration at the distal section of the tubular element to effect the ablation and the vibrational massage therapy for the tissue.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
175 words
An ablation device comprising: (a) an elongated tubular element having a distal section, a distal end, a proximal end, a lumen extending therebetween, and at least one opening at the distal section, wherein at least one electrode is disposed at the distal section; (b) a handle secured at the proximal end of the tubular element, wherein the handle has a cavity; (c) means for generating vibration at the distal section, which is located within the handle, wherein the means for generating vibration at the distal section comprises a motor mounted in the cavity of the handle, which has a rotatable motor shaft, an elongated connecting shaft having a first end to which the electrode is connected, and a second end connected to the handle, a weight eccentrically mounted on the motor shaft with respect to the motor shaft axis, so as to rotate eccentrically, so that when the motor shaft rotates, the electrode vibrates; and (d) RF energy generating means, wherein RF energy is supplied to the at least one electrode through a conducting wire.
Claim 2
Dependent Claim
175 words
An ablation device comprising: (a) an elongated tubular element having a distal section, a distal end, a proximal end, a lumen extending therebetween, and at least one opening at the distal section, wherein at least one electrode is disposed at the distal section; (b) a handle secured at the proximal end of the tubular element, wherein the handle has a cavity; (c) means for generating vibration at the distal section, which is located within the handle, wherein the means for generating vibration at the distal section comprises a motor mounted in the cavity of the handle, which has a rotatable motor shaft, an elongated connecting shaft having a first end to which the electrode is connected, and a second end connected to the handle, a weight eccentrically mounted on the motor shaft with respect to the motor shaft axis, so as to rotate eccentrically, so that when the motor shaft rotates, the electrode vibrates; and (d) RF energy generating means, wherein RF energy is supplied to the at least one electrode through a conducting wire.
Claim 3
Dependent Claim
24 words
The ablation device as in claim 1, wherein the frequency of the vibration is within the range of 60 to 1000 cycles per minute.
Claim 4
Dependent Claim
27 words
The ablation device as in claim 1 further comprising a temperature sensor, wherein the said temperature sensor is disposed at the distal section of the ablation device.
Claim 5
Dependent Claim
35 words
The ablation device as in claim 3, further comprising a temperature control means, wherein the temperature measured from the temperature sensor is relayed to the temperature control means to effect the RF energy generating means.
Claim 6
Dependent Claim
27 words
The ablation device as in claim 1, wherein the electrode is selected from the group of platinum, iridium, gold, silver, Nitinol, or an alloy of their mixtures.
Claim 7
Dependent Claim
66 words
The ablation device as in claim 1 further comprising a therapeutic agent supplied through the at least one opening at the distal section to the exterior of the tubular element, wherein the therapeutic agent is selected from the group consisting of heparin solution, fluoroquinolone, lactic acid, glycolic acid, alpha hydroxy organic acids, vitamins, povidone-iodine, nitrate compounds, virucidal agents, anti-ulcer agents, anti-inflammatory agents, antibiotics, or their mixtures.
