Abstract

A device for delivering a drug includes a body having a proximal end and a distal end and an opening in the distal end thereof. An orifice mechanism at the distal end of the body communicates with the opening. The orifice mechanism includes an inner member having a proximal end and a distal end; a winding helically wound around the inner member; and wherein 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 inner member.

Claims (30)

1. A device for delivering a drug comprising:
a body having a proximal end and a distal end and an opening in the distal end thereof;
an orifice mechanism at the distal end of the body and communicating with the opening, the orifice mechanism comprising:
(i) an inner member having a proximal end and a distal end;
(ii) a winding helically wound around the inner member; and (ii) the winding and the inner member defining a first channel 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.
2. The device according to Claim 1, further comprising a handle at the proximal end of the handle.
3. The device according to Claim 2, further comprising a control on the handle and operatively connected to the distal end of the body for moving the distal end of the body.
4. The device according to Claim 1, further comprising a drug in the body and communicating with the inlet of the winding.
5. The device according to Claim 4, further comprising the drug communicating with the first channel.
6. The device according to Claim 5, wherein the body and the winding define a second channel for carrying the drug therethrough.
7. The device according to Claim 6, further comprising the drug communicating with the second channel.
8. The device according to Claim 5, further comprising the drug communicating with the outlet and the opening.
9. The device according to Claim 7, further comprising the drug communicating with the outlet and the opening.
10. The device according to Claim 3, wherein the device is a catheter.
11. The device according to Claim 3, wherein the device is an intravenous drug delivery device.
12. The device according to Claim 1, wherein the winding further comprises a wire.
13. The device according to Claim 6, wherein the body includes channel filling material for blocking flow of the drug through the second channel.
14. The device according to Claim 12, wherein the wire has a circular shape in cross-section.
