Abstract
A method and apparatus for delivering therapeutic or diagnostic agents as a low pressure high velocity spray into tissue. According to the particular desired spray characteristics, the spray may be generated via the combined use of pressure atomization and electrostatic spray charging, or via the combined use of pressure atomization and electrostatic atomization. Particle velocity, spray flow-rate, and spray dispersion are further controlled via electrostatic means.
