Abstract
A delivery device (10) includes a roller (12) rotatably mounted on an axle (14), a reservoir (40), and one or more hollow needles (16) positioned in the roller (12) in fluid communication with the reservoir (40). As the roller (12) rotates about the longitudinal axis (17) of the axle (14), a piston (30) pushes contents of the reservoir (40) through the needles (16). An actuator (36) is operatively connected to the piston (30) for increasing a pushing force of the piston (30).
