Methods and apparatus for treating disorders of the ear nose and throat
First Claim
1. A method of dilating an anatomical passageway with a device that comprises a handle, an elongate guide shaft that extends distally from the handle and has a guide shaft lumen and is configured to define a bend, a guidewire slidably disposed within the guide shaft lumen, a dilator longitudinally slidable relative to the elongate guide shaft and the guidewire, and a slide member coupled with the dilator, the method comprising:
- (a) positioning a distal end of the elongate guide shaft near an anatomical passageway to be dilated;
(b) advancing the guidewire distally from the elongate guide shaft and into the anatomical passageway;
(c) with the dilator in a non-expanded configuration, sliding the slide member relative to the handle to thereby advance the dilator distally relative to the guidewire, beyond the bend, and into the anatomical passageway while the bend maintains a bent shape; and
(d) transitioning the dilator from the non-expanded configuration to an expanded configuration to thereby dilate the anatomical passageway.

Abstract
A device for dilating an ostium of a paranasal sinus of a human or animal subject may include: a handle; an elongate shaft having a proximal end coupled with the handle and extending to a distal end; a guidewire disposed through at least a portion of the shaft lumen; a dilator having a non-expanded configuration and an expanded configuration; and a slide member coupled with at least one of the guidewire or the dilator through the longitudinal opening of the shaft for advancing the guidewire and/or the dilator relative to the shaft.

1. A method of dilating an anatomical passageway with a device that comprises a handle, an elongate guide shaft that extends distally from the handle and has a guide shaft lumen and is configured to define a bend, a guidewire slidably disposed within the guide shaft lumen, a dilator longitudinally slidable relative to the elongate guide shaft and the guidewire, and a slide member coupled with the dilator, the method comprising:
-
(a) positioning a distal end of the elongate guide shaft near an anatomical passageway to be dilated; (b) advancing the guidewire distally from the elongate guide shaft and into the anatomical passageway; (c) with the dilator in a non-expanded configuration, sliding the slide member relative to the handle to thereby advance the dilator distally relative to the guidewire, beyond the bend, and into the anatomical passageway while the bend maintains a bent shape; and (d) transitioning the dilator from the non-expanded configuration to an expanded configuration to thereby dilate the anatomical passageway. - View Dependent Claims (2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14)

15. A method of dilating an anatomical passageway with a device that comprises a body, an elongate guide shaft that extends distally from the handle and has a guide shaft lumen and is configured to define a bend, a guidewire slidably disposed within the guide shaft lumen, a dilator slidably disposed within the guide shaft lumen and over the guidewire, a first actuating member coupled with the guidewire, and a second actuating member coupled with the dilator, the method comprising:
-
(a) positioning a distal end of the elongate guide shaft near an anatomical passageway to be dilated; (b) moving the first actuating member relative to the body to thereby advance the guidewire distally from the elongate guide shaft and into the anatomical passageway; (c) with the dilator in a non-expanded configuration, moving the second actuating member relative to the body to thereby advance the dilator distally relative to the guidewire, beyond the bend, and into the anatomical passageway while the bend maintains a bent shape; and (d) transitioning the dilator from the non-expanded configuration to an expanded configuration to thereby dilate the anatomical passageway. - View Dependent Claims (16, 17)

18. A method of dilating an anatomical passageway with a device that comprises a body having a longitudinal slot, an elongate guide shaft that extends distally from the handle and has a guide shaft lumen and is configured to define a bend, a guidewire slidably disposed within the guide shaft lumen, a dilator slidably received within the guide shaft lumen and over the guidewire, and an actuating member slidably disposed within the longitudinal slot of the body, the method comprising:
-
(a) positioning a distal end of the elongate guide shaft near an anatomical passageway to be dilated; (b) advancing the guidewire distally from the elongate guide shaft and into the anatomical passageway; (c) with the dilator in a non-expanded configuration, moving the actuating member within the longitudinal slot to thereby actuate the dilator distally relative to the guidewire, beyond the bend, and into the anatomical passageway while the bend maintains a bent shape; and (d) transitioning the dilator from the non-expanded configuration to an expanded configuration to thereby dilate the anatomical passageway. - View Dependent Claims (19)
