Soft palate treatment
A method of treating a soft palate in a patient to treat sleep apnea, snoring or both may involve advancing a treatment element of a treatment device through the patient's mouth, contacting a tissue-contact surface of the treatment element with the soft palate, delivering energy to the soft palate via one or more energy delivery members on the tissue-contact surface, and removing the treatment element from the mouth.
1. A method of treating a soft palate in a patient, without forming an incision or piercing a mucosal surface of the soft palate, to treat sleep apnea, snoring or both, the method comprising:
advancing a treatment element of a treatment device through the patient's mouth;
contacting a tissue-contact surface of the treatment element with the mucosal surface lining the soft palate, without piercing the mucosal surface;
delivering radiofrequency energy from a radiofrequency sinusoid wave generator coupled with a handle of the treatment device to multiple bipolar radiofrequency electrodes on the tissue-contact surface of the treatment element;
delivering the radiofrequency energy from a first row of the multiple bipolar radiofrequency electrodes through the mucosal surface, through an internal tissue of the soft palate, and to a second row of the multiple bipolar radiofrequency electrodes, to heat and change a property of the internal tissue without damaging the mucosal surface;
measuring a temperature of the mucosal surface with at least one sensor on the tissue-contact surface of the treatment element;
providing the temperature to a control unit coupled with the treatment device; and
adjusting, with the control unit, an amount of the radiofrequency energy delivered by the multiple bipolar radiofrequency electrodes, based on the temperature.
2. A method as in claim 1 , wherein the multiple bipolar radiofrequency electrodes comprise protruding, non-penetrating electrodes, and wherein delivering the radiofrequency energy at least one of reshapes, remodels, stiffens, shrinks an strengthens the internal tissue of the soft palate.
3. A method as in claim 2 , wherein the treatment device further comprises:
a shaft extending from the handle and defining a longitudinal axis; and
a neck disposed between the shaft and the treatment element, wherein the treatment element is attached to the neck so as to position the treatment element at an angle relative to the longitudinal axis of the shaft.
4. A method as in claim 1 , further comprising applying force against the soft palate with the tissue-contact surface while delivering the energy, to at least temporarily deform the internal tissue of the soft palate, wherein the internal tissue at least partially retains a deformed shape after the treatment device is removed from the patient's mouth.
5. A method as in claim 1 , wherein the internal tissue of the soft palate is selected from the group consisting of submucosal tissue, cartilage and collagen.
6. A method as in claim 1 , wherein the radiofrequency sinusoid wave generator comprises a 460 kHz radiofrequency sinusoid wave generator.
7. A method as in claim 1 , wherein delivering the energy to the internal tissue of the soft palate comprises heating the internal tissue, the method further comprising maintaining the temperature of the mucosal surface at a lower temperature than a heated temperature of the internal tissue.
8. A method as in claim 1 , wherein the at least one sensor comprises at least one thermocouple positioned between at least two of the multiple bipolar radiofrequency electrodes.
