Abstract
Subcutaneous injection of gas into a body causes insufflation of a cavity, which is followed by infusion of a fluid into the cavity. The fluid preferably carries an active agent, for example a dissolved gas or solute. The method may include iontophoresis of the cavity to enhance diffusion of the active agent into target tissue. Additional steps may be employed to monitor needle tip location to avoid causing damage to an organ by coming into contact with the needle tip or by injecting a gas into a blood vessel.
