The subject devices comprise a shaft having a distal end, a proximal end, a curved region located between the distal and proximal ends, and an interior channel, an extensible and retractable guide wire movably mounted within the interior channel and a probe tip joined to the guide wire. Certain devices further include expandable portions for engaging and treating body anatomy. ## Claims ### Claim at position 1 -56. (canceled) ### Claim 57 An apparatus comprising: (a) a handle assembly; (b) an elongate body comprising a proximal portion, a distal portion, wherein the elongate body defines an inflation lumen, wherein the proximal portion of the elongate body defines a longitudinal axis, wherein the elongate body extends distally from the handle assembly, wherein the distal portion of the elongate body terminates into a distal end dimension to be interested within a nasal cavity; and (c) a balloon attached to the distal portion of the elongate body, wherein the balloon is in fluid communication with the inflation lumen of the elongate body, wherein the balloon is configured to transition between a deflated configuration and an inflated configuration, wherein the balloon comprises an asymmetrical profile relative to a plane extending along a length of the distal portion of the elongate body. ### Claim 58 (depends on 57) The apparatus of claim 57, wherein the balloon is non-concentric relative to the distal portion of the elongate body. ### Claim 59 (depends on 57) The apparatus of claim 57, wherein the balloon comprises multiple diameters along the length of the distal portion of the elongate body. ### Claim 60 (depends on 57) The apparatus of claim 57, wherein the balloon comprises multiple taper geometries along the length of the distal portion of the elongate body. ### Claim 61 The apparatus of 57, wherein the balloon terminates prior to the distal end of the distal portion of the elongate body. ### Claim 62 (depends on 57) The apparatus of claim 57, wherein the balloon extends past the distal end of the distal portion of the elongate body. ### Claim 63 (depends on 57) The apparatus of claim 57, wherein the balloon comprises a round cross-sectional geometry. ### Claim 64 (depends on 57) The apparatus of claim 57, wherein the balloon comprises a non-round cross-sectional geometry. ### Claim 65 (depends on 57) The apparatus of claim 57, wherein the handle assembly comprises a luer fitting in fluid communication with the balloon. ### Claim 66 (depends on 57) The apparatus of claim 57, wherein the elongate body comprises a malleable region extending from the handle assembly. ### Claim 67 (depends on 57) The apparatus of claim 57, wherein the elongate body comprises a semi-rigid region extending from the handle assembly. ### Claim 68 (depends on 57) The apparatus of claim 57, wherein the distal portion of the elongate body comprises a curved portion, wherein the balloon is disposed on the curved portion. comprises a hook shape. ### Claim 69 (depends on 68) The apparatus of claim 68, wherein the curved portion comprises a uncinate hook. ### Claim 70 (depends on 57) The apparatus of claim 57, wherein the balloon comprises a built-in curve. ### Claim 71 (depends on 57) The apparatus of claim 57, wherein the balloon comprises an infundibulum balloon region, a bullar balloon region, and a middle meatal balloon region. ### Claim 72 (depends on 57) The apparatus of claim 57, wherein the balloon comprises a first region, a second region, and a third region, wherein each region comprises a different thickness. ### Claim 73 (depends on 57) The apparatus of claim 57, wherein the distal end comprises a ball tip. ### Claim 74 (depends on 57) The apparatus of claim 57, wherein the balloon comprises an asymmetrical longitudinal profile relative to the longitudinal profile of the proximal portion of the elongate body. ### Claim 75 An apparatus comprising: (a) an elongate body comprising a proximal portion, a distal portion, wherein the proximal portion of the elongate body defines a longitudinal axis, wherein the distal portion of the elongate body terminates into a distal end dimensioned to be interested within a nasal cavity; and (b) a balloon attached to the distal portion of the elongate body, wherein the balloon is configured to transition between a deflated configuration and an inflated configuration, wherein the balloon comprises an asymmetrical profile relative to a plane extending along a length of the distal portion of the elongate body. ### Claim 76 An apparatus comprising: (a) an elongate body comprising a semi-rigid proximal portion, a distal portion, wherein the elongate body defines an inflation lumen, wherein the semi-rigid proximal portion of the elongate body defines a longitudinal axis, wherein the semi-rigid proximal portion of the elongate body is attached to the handle assembly, wherein the distal portion of the elongate body terminates into a distal end dimension to be interested within a nasal cavity; and (b) a balloon attached to the distal portion of the elongate body, wherein the balloon is in fluid communication with the inflation lumen of the elongate body, wherein the balloon is configured to transition between a deflated configuration and an inflated configuration, wherein the balloon comprises an asymmetrical profile relative to a plane extending through a central axis of the distal portion of the elongate body.
