Abstract

Medical devices, systems and methods that are useable to facilitate transnasal insertion and positioning of guidewires and various other devices and instruments at desired locations within the ear, nose, throat, paranasal sinuses or cranium. Direct viewing of such placements via an endoscope.

Claims

1-38. -38. (canceled)

39. A guide device useable to position a working device at a desired location within the ear, nose, throat or cranium of a human or animal subject, said device comprising:

a transnasally insertable elongate shaft having a proximal end and a distal end;

a first channel into which an endoscope may be inserted so that the endoscope may be used to view at least an area beyond the distal end of the shaft; and

a second channel through which the working device may be advanced, wherein said first channel is statically located relative to said second channel.

40. The device of claim 39, wherein said first channel is removably fixed to said second channel.

41. The device of claim 39, further comprising a proximally located handle, wherein proximal end portions of said first and second channels extend through said handle.

42. The device of claim 41, wherein said proximal end portions diverge away from one another in a direction from a distal end of said handle to a proximal end of said handle.

43. The device of claim 41, wherein said second channel is rotatable within said handle and said first channel is fixed to said handle, prevent rotation of said first channel relative to said handle.

44. The device of claim 41, further comprising a second handle mounted on one of said first and second channels, proximal of said first handle.

45. The device of claim 44, wherein said second handle is mounted on said second channel.

46. The device of claim 43, further comprising a second handle mounted on said second channel, proximal of said first handle, wherein said second handle is fixed to said second channel to prevent rotation of said second channel relative to said second handle.

47. The device of claim 39, further comprising an overlamination or heat shrink tube surrounding said first and second channels.

48. The device of claim 39, wherein a distal end of said first channel is set back proximally of a distal end of said second channel by a predetermined distance.

49. The device of claim 39, where a distal tip portion of said first channel is colored with a color that contrasts with a color of a portion of said first channel proximally adjacent said distal tip portion.

50. The device of claim 39, where a distal tip portion of said second channel is colored with a color that contrasts with a color of a portion of said second channel proximally adjacent said distal tip portion.

51. The device of claim 39, wherein said first channel comprises an oblique distal tip.

52. The device of claim 39, wherein a proximal end of at least one of said first and second channels is fitted with a luer connector.

53. The device of claim 42, wherein a channel in said handle directing said proximal end portion of said first channel away from said second channel comprises a bend, said bend creating frictional resistance on an endoscope inserted in said first channel as the endoscope passes through said bend.

54. The device of claim 49, wherein said distal end of said first channel comprises an oblique distal tip.
