    • 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.
    • 用于将药液或软膏递送至鼻旁窦的目标区域的装置。 提供了灵活的双腔导管。 第一管腔可释放地附接到流体源。 第二腔基本上相邻并平行于第一腔,并且可释放的接受可变形构件,例如可延展的线。 通过将可变形构件弯曲成期望的形状,柔性第二内腔又相邻的柔性第一内腔呈现接近可变形构件的曲率的曲率。 此外,提供了具有导管组件和多个适配器的刚性输送组件。
