The manipulator also includes an adjuster that is configured to slide in the U-shaped channel. The adjuster includes a first wheel which on rotation translates a guidewire positioned in the adjuster along an axis of the guidewire, and a second wheel which on rotation rotates the guidewire positioned in the adjuster about the axis of the guidewire. The adjuster also includes a port, distal to the first and the second wheel, that is configured to accept a tubular balloon and the guidewire. ## Claims ### Claim 1 A guidewire, comprising: (a) a plastic tube forming a lumen, the plastic tube being configured to be inserted into a nasal sinus and having a length; (b) a braid incorporated into the plastic tube; and (c) a metal wire located in the lumen along the length of the plastic tube, the plastic tube including a first plastic tube cemented to a second plastic tube, the lumen being common to the first plastic tube and the second plastic tube, and the first and second plastic tube having different thicknesses and a same outside diameter along the length of the plastic tube. ### Claim 2 (depends on 1) The guidewire according to claim 1, the first and second plastic tubes having differing flexibilities. ### Claim 3 (depends on 1) The guidewire according to claim 1, the braid including stainless steel. ### Claim 4 (depends on 1) The guidewire according to claim 1, the braid including a polymer. ### Claim 5 (depends on 1) The guidewire according to claim 1, the braid being embedded within the plastic tube. ### Claim 6 (depends on 1) The guidewire according to claim 1, further comprising a position sensor disposed within the lumen at a distal end of the plastic tube. ### Claim 7 (depends on 6) The guidewire according to claim 6, the position sensor including a coil configured to interact with an alternating magnetic field to output a data signal indicative of a position and an orientation of the coil relative to the nasal sinus. ### Claim 8 (depends on 7) The guidewire according to claim 7, further comprising one or more wires disposed within the lumen, the one or more wires being coupled with the coil and configured to transmit the data signal to a processor. ### Claim 9 (depends on 7) The guidewire according to claim 7, the coil being wound around a tube, the tube defining a bore, and the metal wire being positioned within the bore. ### Claim 10 (depends on 1) The guidewire according to claim 1, further comprising a cement plug coupled with a distal tip of the plastic tube. ### Claim 11 (depends on 1) The guidewire according to claim 1, the plastic tube defining a longitudinal axis and the metal wire being positioned on the longitudinal axis. ### Claim 12 (depends on 1) The guidewire according to claim 1, the braid being embedded within the plastic tube and forming a cylindrical shape; and the braid and the plastic tube being coaxial. ### Claim 13 (depends on 1) The guidewire according to claim 1, the metal wire including a distal portion and a proximal portion and the distal portion of the metal wire being bent relative to the proximal portion of the metal wire. ### Claim 14 A guidewire, comprising: (a) a flexible tube including a proximal end and a distal end, the flexible tube forming a lumen, the flexible tube being configured to be inserted into a nasal sinus the flexible tube defining a longitudinal axis, the flexible tube having a same outside diameter along a length of the flexible tube and the proximal end having a greater thickness than the distal end; (b) a braid being incorporated coaxially embedded within the flexible tube relative to the longitudinal axis; and (c) a support wire being disposed in the lumen. ### Claim 15 (depends on 14) The guidewire according to claim 14, the flexible tube including a first portion axially adjoined with a second portion and the lumen being common to the first portion and the second portion. ### Claim 16 (depends on 15) The guidewire according to claim 15, the first and second portions of the flexible tube having differing thicknesses. ### Claim 17 (depends on 14) The guidewire according to claim 14, further comprising a position sensor disposed within the lumen at the distal end of the flexible tube. ### Claim 18 (depends on 14) The guidewire according to claim 14, further comprising a coil being wound around a sensor tube, the sensor tube defining a bore, and the support wire being positioned within the bore. ### Claim 19 A guidewire, comprising: (a) a flexible tube configured to be inserted into a paranasal passageway, including: (i) a proximal tube portion defining a proximal end, and (ii) a distal tube portion defining a distal end, the proximal and distal tube portions being axially adjoined and defining a lumen therethrough from the proximal end of the proximal tube portion to the distal end of the distal tube portion and the proximal tube portion and distal tube portion having differing flexibilities; and (b) a support braid being embedded within the flexible tube from the proximal end to the distal end, the flexible tube having a same outside diameter in both the proximal tube portion and the distal tube portion, the proximal tube portion having a proximal inner diameter, the distal tube portion having a distal inner diameter, and the proximal inner diameter being smaller than the distal inner diameter, and the proximal tube portion having a greater thickness than the distal tube portion. ### Claim 20 (depends on 19) The guidewire according to claim 19, further comprising a support wire being disposed in the lumen.
