Abstract
An orifice device for delivering a drug includes an inner member having a proximal end and a distal end. A winding is helically wound around the inner member. The winding and the inner member define a first channel for carrying a drug therethrough. An inlet is at the proximal end of the winding and an outlet is at the distal end of the winding.
Claims18
An orifice device for delivering a drug comprising:
- an inner member having a proximal end and a distal end;
- a winding helically wound around the inner member, wherein the winding comprises a wire and wherein the wire has a width ranging from 0.001-0.050 inches;
- the exterior surface of the winding and the inner member defining a first channel having a helical flowpath following the curvature of the winding for carrying a drug therethrough and an inlet at the proximal end of the winding and an outlet at the distal end of the winding;
- a first drug carrying path defined by a first inlet at the proximal end of the winding, the first channel having a helical flowpath following the curvature of the winding, and a first outlet at the distal end of the winding;
- an outer member over the winding, wherein the exterior surface of the winding and the outer member define a second channel having a helical flow path following the curvature of the winding for carrying a drug therethrough;
- and
- a second drug carrying path defined by a second inlet at the proximal end of the winding, the second channel having a helical flowpath following the curvature of the winding, and a second outlet at the distal end of the winding, wherein the first and second drug carrying paths are capable of delivering two separate drugs.
