Abstract
Methods and devices for treating nasal airways are provided. Such devices and methods may improve airflow through an internal and/or external nasal valve, and comprise the use of mechanical re-shaping, energy application and other treatments to modify the shape, structure, and/or air flow characteristics of an internal nasal valve, an external nasal valve or other nasal airways.
Claims15
A device for treating a targeted nasal tissue from within a nasal cavity, the device comprising:
- a handle;
- a shaft extending from the handle;
- an expandable treatment element disposed on the shaft, comprising multiple shape memory material segments;
- and
- multiple rows of multiple pairs of bipolar radio frequency electrodes disposed on the expandable treatment element;
- wherein the expandable treatment element is configured to contact mucosal tissue lining the nasal cavity and transmit radiofrequency energy from the multiple pairs of bipolar radiofrequency electrodes, such that the radiofrequency energy passes through the mucosal tissue to treat the targeted nasal tissue at a selected tissue depth below the mucosal tissue, and
- wherein the expandable treatment element is configured to expand to a size and a shape to position the multiple pairs of bipolar radiofrequency electrodes in contact with the mucosal tissue.
4 more elements
A device for treating a targeted nasal tissue from within a nasal cavity, the device comprising:
- a handle;
- a shaft extending from the handle;
- a plurality of expandable treatment elements disposed on the shaft, comprising multiple shape memory material segments;
- and
- multiple rows of multiple pairs of bipolar radiofrequency electrodes disposed on each expandable treatment element of the plurality of expandable treatment elements;
- wherein the plurality of expandable treatment elements is configured to contact mucosal tissue lining the nasal cavity and transmit radiofrequency energy from the multiple pairs of radiofrequency electrodes, such that the radiofrequency energy passes through the mucosal tissue to treat the targeted nasal tissue at a selected tissue depth below the mucosal tissue, and
- wherein the plurality of expandable treatment elements is configured to expand to a size and a shape to position the multiple pairs of radiofrequency electrodes in contact with the mucosal tissue.
