Abstract
Particular aspects provide novel atomizers for generating particles over a broad range of MMAD size distributions, the eliminating the requirement for an impaction baffle in generating the desired particle sizes. In particular aspects, the atomization means communicates with a remote particle filter member configured and positioned to provide for particle size filtering. In additional aspects, the atomization means communicates with a particle dispersion chamber suitable to impart a desired particle flow pattern to particles within and exiting the dispersion chamber. In further aspects, the atomization means communicates with a nasal, ocular, oral or ‘vicinity’ adapter. The novel devices provide for targeted (e.g., nasal, ocular, oral, local vicinity), systemic, and/or topical delivery of an atomized liquid (e.g., via the nasal cavity, olfactory region, and mouth). Further exemplary aspects relate to aerosolization and delivery of perfume, fragrance, essential oil or cosmeceutical agents and the like.
