Abstract
Disclosed embodiments include devices and methods for shaping, bending, and/or volumetrically reducing rigid cartilaginous structures, such as hyaline cartilage in the septum. In the case of septal cartilage, shaping, bending, or reducing the cartilage would be useful for reducing nasal obstruction or to improve the cosmetic appearance of the nose.
Claims22
A method for treating a deviated nasal septum of a subject's nose, the method comprising:
- injecting a substance under nasal mucosa and into contact with cartilage of the deviated nasal septum, wherein the substance is configured to modify a property of the cartilage;
- inserting a channel stylus device into the subject's nose, the channel stylus device comprising;
- a handle;
- an elongate shaft extending from the handle;
- an elongate treatment element configured to create at least one channel in the deviated nasal septum;
- and
- multiple bipolar radiofrequency electrode pairs disposed in one line along the elongate treatment element;
- applying force to the deviated nasal septum with the elongate treatment element of the channel stylus device, to create the at least one channel in the deviated nasal septum;
- and
- delivering radiofrequency energy from the multiple bipolar radiofrequency electrode pairs of the channel stylus device to a selected tissue depth in the deviated nasal septum, to cure, deactivate, or denature the injected substance and modify the property of the cartilage of the deviated nasal septum and thus treat the deviated nasal septum.
