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.
Claims18
A device configured for treatment of obstructive sleep apnea, comprising:
- an applicator configured to receive a circulating fluid from a temperature determinant, the applicator being sized and configured to contact an oropharyngeal tissue and including—
- a bottom half having a tissue contacting surface and a temperature sensor positioned at the tissue contacting surface, and
- a top half coupled to the bottom half and having one or more leads coupled to the temperature sensor, wherein the one or more leads extend from the bottom half of the applicator to the temperature sensor;
- a fixture arm configured to be coupled to the applicator and adjust the applicator with respect to a positioning of the tissue contacting surface, the fixture arm including an electrical circuit electrically coupled to the temperature sensor;
- and
- a controller configured to facilitate heat transfer between the applicator and the circulating fluid.

A device for treatment of obstructive sleep apnea, the device comprising:
- an applicator configured to receive a circulating fluid from a temperature determinant, the applicator being sized and configured to contact an oropharyngeal tissue and including—
- a bottom half having a tissue contacting surface and a temperature sensor positioned at the tissue contacting surface, and
- a top half coupled to the bottom half and having one or more leads coupled to the temperature sensor, wherein the one or more leads extend from the bottom half of the applicator to the temperature sensor;
- a fixture arm configured to be coupled to the applicator and adjust the applicator with respect to a positioning of the tissue contacting surface;
- a feedback system operably coupled to the temperature sensor and configured to monitor one or more temperature measurements at the tissue contacting surface;
- and
- a controller configured to facilitate heat transfer between the applicator and the circulating fluid based on the feedback system.
4 more elements
A device configured for treatment of obstructive sleep apnea, comprising:
- an applicator configured to receive a circulating fluid from a temperature determinant, the applicator being sized and configured to contact an oropharyngeal tissue and including—
- a bottom portion having a tissue contacting surface and a temperature sensor positioned at the tissue contacting surface, and
- a top portion coupled to the bottom portion and having one or more leads coupled to the temperature sensor, wherein the one or more leads extend from the bottom portion of the applicator toward the temperature sensor;
- and
- a fixture arm configured to be coupled to the applicator and adjust the applicator with respect to a positioning of the tissue contacting surface.
