4 . The method of claim 2 , wherein applying the heat source to at least a portion of the polymeric tube comprises:
applying the heat source adjacent the distal end of the guide wire to secure the electromagnetic sensor to the distal end of the guide wire.
5 . The method of claim 1 , further comprising:
potting the electromagnetic sensor in an epoxy.
6 . The method of claim 1 , positioning the electromagnetic sensor at the distal end of the guide wire comprises:
securing the electromagnetic sensor to the distal end of the guide wire via a radio frequency tipping die.
7 . The method of claim 1 , further comprising:
positioning a camera at the distal end of the guide wire.
8 . The method of claim 1 , further comprising:
applying a lubricious coating to the guide wire.
9 . A method of treating a sinus cavity of a subject, the method comprising:
(a) inserting a distal portion of a guide wire system into a lumen of a balloon dilation catheter, wherein the guide wire system includes:
(i) a guide wire having a distal end and a proximal end,
(ii) a first connector positioned at and coupled to the proximal end of the guide wire, and
(iii) a second connector coupled to the guide wire between the distal end and the proximal end;
(b) coupling the second connector of the guide wire system to the balloon dilation catheter such the distal end of the guide wire is fixed with respect to a distal end of the balloon dilation catheter;
(c) directing the distal end of the guide wire and the distal end of the balloon dilation catheter to the sinus cavity; and
(d) inflating a balloon.
10 . The method of claim 9 , wherein the guide wire system further comprises:
an electromagnetic sensor coupled to the distal end of the guide wire.
11 . The method of claim 10 , wherein directing the distal end of the guide wire and the distal end of the balloon dilation catheter to the sinus cavity comprises:
directing the distal end of the guide wire and the distal end of the balloon dilation catheter simultaneously to a drainage pathway of the sinus cavity using data received from the electromagnetic sensor.
12 . The method of claim 11 , wherein the drainage pathway of the sinus cavity comprises a frontal recess of a frontal sinus cavity.
13 . The method of claim 10 , wherein the guide wire system further comprises:
a polymeric tube surrounding at least a portion of the guide wire and at least a portion of the electromagnetic sensor.

an inner guide member including the lumen.
15 . The method of claim 14 , wherein the balloon dilation catheter further includes a movable shaft coupled to the balloon and mounted on the inner guide member, and wherein the method further comprises:
allowing the movable shaft to move along the inner guide member, while preventing the movable shaft from rotating around the inner guide member.
16 . The method of claim 9 , further comprising:
re-positioning the distal end of the balloon dilation catheter based at least in part on a determined location of the distal end of the guide wire with respect to the sinus cavity.
17 . The method of claim 16 , further comprising:
prior to re-positioning the distal end of the balloon dilation catheter, deflating the balloon; and
re-inflating the balloon once the distal end of the balloon dilation catheter is re-positioned.
18 . The method of claim 9 , wherein the first connector comprises a pin connector, and wherein the second connector comprises a bayonet connector, and wherein the method further comprises:
coupling the guide wire system to the balloon dilation catheter via coupling the bayonet connector of the second connector to a complementary bayonet connector of the balloon dilation catheter.
