Patent ID: 8435261

Claim:
A device for accessing a sinus ostium, comprising: a catheter extending from a proximal end to a distal end, a portion of the distal end includes an arcuate shaped housing, the catheter including a longitudinally-extending lumen and an intersecting side portal located proximal to the distal end; and a probe including a first portion and a second portion separated by a preformed bend, which is adjacent to and consistent with the arcuate shaped housing, the first portion extending from a probe proximal end to the preformed bend and the second portion extending from the preformed bend in a direction toward the probe proximal end; wherein the probe is at least partially nested within the arcuate shaped housing and the longitudinally-extending lumen and a portion of the probe is movable within the lumen such that a probe tip is advanceable out of the intersecting side portal and housing.
