Abstract
Nasal airway reshaping is accomplished using a fractional treatment device applied externally to the nose to insert needle electrodes into nasal tissue to be reshaped. Energy is applied via the electrodes to cause at least partial coagulation of the nasal tissue within zones around each of the plurality of needle electrodes while pressure is applied internally to achieve the desired reshaping.
Claims12
A method of reshaping a nasal airway, the method comprising:
- applying mechanical pressure from inside a nostril to reshape a portion the nasal airway;
- inserting, to a predetermined depth, a plurality of needle electrodes of a hand piece through an external skin surface of the nose into nasal tissue adjacent to the reshaped portion;
- and
- applying a predetermined amount of radiofrequency (RF) energy via the plurality of needle electrodes after insertion to cause at least partial coagulation of the nasal tissue within respective zones around each of the plurality of needle electrodes;
- wherein a portion of each of the plurality of needle electrodes is coated with an insulating material to minimize application of RF energy adjacent to the portion;
- and
- wherein each portion is closer to the hand piece than a remaining, uninsulated portion of each of the plurality of needle electrodes.
