Abstract
Methods of actuating a needle array device can include causing fluid to move through flow channels to needle apertures that are spaced apart from an inflow aperture at different distances where flow channels that have approximately equal pathway lengths and where the fluid can reach tips of the needle apertures approximately simultaneously, which can provide an approximately equal dosage or fluid volume through the tips of the needle apertures.
Claims20
A method of actuating a needle array device comprising causing a fluid to pass from an inflow aperture to needle apertures that are spaced apart from the inflow aperture at different distances, the fluid passing through a plurality of flow channels that have approximately equal pathway lengths thereby permitting the fluid to reach tips of the needle apertures approximately simultaneously.
A method of actuating a needle array device comprising injecting a fluid into a fluid manifold that diverts the fluid into a plurality of flow channels that have approximately equal lengths and terminal ends positioned at different distances from an inflow aperture fluidly coupled to the fluid manifold.
