Abstract
Methods, devices, and systems employ cryolysis of oropharyngeal adipose tissues to selectively remove fat cells from the tissues causing obstructive sleep apnea. In various embodiments, a chilled liquid—e.g., a liquid or air—is applied to the target tissue at a temperature and for a duration sufficient to cause cryolysis.
Claims12
A device for treatment of obstructive sleep apnea, comprising:
- a shaft;
- an engagement member disposed at a distal end of the shaft and having a contact surface shaped to be complementary to an oropharyngeal tissue target and to cool the oropharyngeal tissue target;
- a sensor disposed on the engagement member;
- a cooling unit;
- a lumen disposed in the shaft and in communication with the engagement member and the cooling unit to circulate a cooling fluid through the engagement member;
- and
- a processor operatively coupled to the cooling unit and the sensor, the processor being configured to responsively adjust a temperature of the cooling fluid with the cooling unit to achieve and maintain a desired temperature of the engagement member sufficient to cause cryolysis of adipose tissue within the oropharyngeal tissue target.
