ABSTRACT:
Devices for improving nasal breathing and to nasal drug delivery devices having two end portions of a resilient material in the form of relatively thin tabs, perferably having a gentle curvature, interconnected by a resilient member. Upon bending of the connecting member, the two end tabs can be positioned in respective nostrils where they will be biased outwardly against the nasal side walls, the outward biasing force being sufficient to locate the device in the nose and to dilate the anterior part of each nasal cavity by an amount to improve nasal breathing. No part of the device is grippingly engaged with the septum and a substantial free passage for air flow remains between the septum wall and the nasal side wall-contacting face of each end tab.
