Abstract
An applicator for delivering a bioactive composition includes a jet dispenser having an orifice for ejection of droplets from the dispenser. The jet dispenser further includes a main body. At least partially insertable through the main body is a replaceable fluid reservoir for holding and delivering the bioactive composition to the orifice for ejection therethrough. A body orifice spacer is positioned between the orifice of the dispenser and a target during ejection of the bioactive composition to the target.
