ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to an internal nasal implant for opening a nasal valve of a human nasal cavity
BACKGROUND OF THE INVENTION
The narrowest area in the nasal cavity is referred to as the nasal valve. The nasal valve is located at the junction of the upper and lower lateral cartilage and includes the nasal septum. The upper lateral cartilage on each side of the nasal cavity is the only portion of the nasal valve that collapses during inspiration of air. The nasal cavity accounts for 50-60% of total airway resistance. Numerous non-implantable products and surgical procedures are available to increase the area of the nasal valve and to decrease nasal airflow resistance.
SUMMARY OF THE INVENTION
The present invention is an internal nasal implant for opening nasal valves of a human nasal cavity. The nasal implant includes an elongate body of biocompatible material having a length to span dorsal surface portions of first and second upper lateral cartilage of a human nose. The elongate body has a first end portion and a second end portion connected by a base portion to form an overall V-shape. The first end portion and the second end portion are capable of biasing the first and second upper lateral cartilage apart to increase airflow through the nasal valves.
