Claim of US Patent No. 9,826,999

1. A device for dilating an ostium of a paranasal sinus of a human or animal subject, the device comprising:
(a) a handle comprising a proximal end and a distal portion;
(b) an elongate guide shaft extending distally from the handle, wherein the elongate guide shaft defines a guide shaft lumen,
said elongate shaft comprising a proximal portion and a distal end, wherein the distal end comprises a preformed fixed bend;

(c) a guidewire slidably positioned within the guide shaft lumen;
(d) a dilator configured to transition between a non-expanded configuration and an expanded configuration, wherein the dilator
is configured to fit in an ostium of a paranasal sinus in the non-expanded configuration, wherein the dilator is longitudinally
slidable relative to the elongate guide shaft and relative to the guidewire; and

(e) a first slide member coupled with the dilator, wherein the first slide member is located between the proximal end and
the distal portion of the handle, wherein the first slide member is slidable relative to the handle, wherein the first slide
member is operable to slide the dilator longitudinally relative to the elongate guide shaft past the preformed fixed bend
to a position that is distal of a tip of the elongate guide shaft without dilating the dilator, wherein the preformed fixed
bend is configured to not change shape as the dilator moves past the preformed fixed bend.
