Abstract

An apparatus for delivering a medicated fluid or ointment to a target region of the paranasal sinuses. A flexible dual lumen catheter is provided. A first lumen is releasably attachable to a fluid source. A second lumen is substantially adjacent and parallel to the first lumen, and releasable accepts a deformable member, such as a malleable wire. By bending the deformable member into a desired shape, the flexible second lumen and, in turn, the adjacent flexible first lumen, assume a curvature approximating that of the deformable member. Further, a rigid delivery assembly is provided having a catheter assembly and a plurality of adaptors.

Claims

1. A fluid delivery catheter apparatus comprising:

a first lumen having an inlet port, an outlet port, and an elongated body disposed between the inlet port and the outlet port;

a second lumen, at least a portion of the second lumen being substantially adjacent the first lumen;

a deformable member, at least a portion of the deformable member being retainable by the second lumen;

whereby deforming at least a portion of the deformable member to a non-linear shape in turn causes at least a portion of the first lumen to assume a shape approximating the non-linear shape of at least a portion of the deformable member.

2. The invention according to claim 1, wherein the first lumen further includes a connecting region operably attachable to a supply of fluid.

3. The invention according to claim 2, wherein the connecting region comprises a Luer-Lock connection.

4. The invention according to claim 2, wherein the supply of fluid comprises a syringe.

5. The invention according to claim 2, wherein the supply of fluid comprises a fluid delivery assembly.

6. The invention according to claim 5, wherein the fluid delivery assembly includes a body having a pistol grip.

9. The invention according to claim 1, wherein at least a portion of at least one of the first lumen and the second lumen are constructed of a substantially flexible material.

10. The invention according to claim 9, wherein the substantially flexible material is an elastorneric silicone material.

12. The invention according to claim 1, wherein the deformable member comprises a malleable wire.

13. The invention according to claim 12, wherein at least a portion of the malleable wire is preformed to create a graspable member.

14. The invention according to claim 1, wherein the first lumen further includes an olive tip proximate the outlet port.

15. The invention according to claim 1, further comprising a substantially rigid region associated with the first lumen.

16. The invention according to claim 15, wherein the substantially rigid region substantially surrounds at least a portion of a proximal end of the first lumen.

17. The invention according to claim 15, wherein at least a portion of the substantially rigid region comprises a grasping region.

18. A fluid delivery catheter apparatus comprising:

a catheter assembly having a tube with a proximal end and a distal end, a first connector coupled to the proximal end and adapted for coupling to a syringe or other fluid delivery system, and a second connector coupled to the distal end; and

an adaptor having a tube with a proximal end and a distal end, the proximal end having a connector for removably coupling to the first second connector of the catheter assembly.

19. The apparatus of claim 18, wherein a substantial portion of the tube extends at an angle from the longitudinal axis of the first connector of the catheter assembly, preferably at an angle of approximately 30 degrees.

20. The apparatus of claim 18, wherein a substantial portion of the tube extends at an angle from the longitudinal axis of the adaptor connector.

21. The apparatus of claim 18, wherein the first connector is a Luer type connector for coupling to a syringe or other fluid delivery system.

22. The apparatus of claim 18, wherein the second connector includes a pin extending through the walls of the tube at a right angle to the longitudinal axis of the tube.

23. The apparatus of claim 18, wherein the catheter assembly and the adaptor are rigid.
