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.
Claims15
A method for treating obstructive sleep apnea in a subject, the method comprising steps of:
- providing a device which comprises:
- a. a cooling unit for chilling a cooling fluid;
- and
- b. an applicator for receiving the cooling fluid, the applicator comprising an engagement member which is shaped to be complementary to a target surface of oropharyngeal tissue;
- cooling the engagement member to a temperature between approximately 5° C. and approximately −25° C.;
- and
- placing the engagement member in contact with the target surface of the oropharyngeal tissue in the subject for a time sufficient to cause cryolysis of adipose tissue within the oropharyngeal tissue, and thereby reduce a volume of the adipose tissue.
