Abstract
An orifice device for delivering one or more drugs includes an inner member having a proximal end and a distal end; and a winding helically wound around the inner member. The winding includes a plurality of distinct wires helically wound in parallel around the inner member. The winding and the inner member define at least three separate channels for carrying one or more drugs therethrough. An inlet is at the proximal end of the winding and an outlet is at the distal end of the winding for the plurality of distinct wires. In some embodiments, at least two of the plurality of distinct wires have a different dimension. An outer member is used over the winding. Also, at least two of the at least three separate channels have a different fluid flow rate. And, in some embodiments, at least two of the at least three separate channels carry a different drug.
