Ophthalmic drug delivery using a charge isolated ejector mechanism
The patent US12029682B2 outlines a method for delivering a low dosage volume medicament composition directly to the eye of a subject, utilizing a charge isolated ejector mechanism. This method involves generating a directed stream of droplets containing the medicament, which is specifically designed to deposit on the cornea. The ejector mechanism is characterized by a piezoelectric actuator that oscillates a generator plate with multiple openings, facilitating the precise delivery of droplets. The claims specify that the volume of medicament delivered can be as low as 6 microliters, significantly less than the volume typically dispensed by standard eyedroppers. The method aims to ensure that at least 75% of the droplet mass effectively reaches the cornea, with droplet diameters ranging from 20 to 400 microns and initial velocities between 0.5 m/s and 10 m/s.
Additionally, the patent identifies specific medicaments suitable for this delivery method, including various glaucoma treatments such as travoprost and latanoprost. The claims further elaborate on the structural components of the charge isolated ejector mechanism, which includes a flexible printed circuit with a laminate structure that separates the piezoelectric actuator from other components to maintain charge isolation. The design also incorporates an ejector plate that enhances the delivery process without obstructing the droplet formation. Overall, this patent presents a novel approach to ocular drug delivery, focusing on efficiency and precision in treating eye conditions, particularly glaucoma.
