Abstract
An implantable device for delivering a drug includes a housing and a source of drug contained within the housing. An orifice mechanism is located at the housing and communicates with the source of drug. The orifice mechanism includes an inner member having a proximal end and a distal end and a winding helically wound around the inner member. The winding and the inner member define a first channel for carrying the drug therethrough. An inlet is at the proximal end of the winding and an outlet is at the distal end of the winding. The drug is carried by the orifice mechanism and dispensed outside of the housing.
