INFLATOR FOR DILATION OF ANATOMICAL PASSAGEWAY

A dilation catheter system (10) is provided to dilate the ostium of a paranasal sinus or some other anatomical passageway (e.g. within the ear nose or throat etc.). The system may include a dilation catheter (20) a dilator (22) a guide catheter (30) and an inflator (40). The dilation catheter (20) m...

Beschreibung
Zusammenfassung:	A dilation catheter system (10) is provided to dilate the ostium of a paranasal sinus or some other anatomical passageway (e.g. within the ear nose or throat etc.). The system may include a dilation catheter (20) a dilator (22) a guide catheter (30) and an inflator (40). The dilation catheter (20) may be positioned between the dilator (22) and the inflator (40 1150). The guide catheter (30) is configured to guide the dilator (22) into the affected passageway. The inflator (40 1150) may then be actuated to transfer fluid from the inflator through the dilation catheter (20) and into the dilator (22). The transfer of fluid may inflate the dilator to an expanded state to open or dilate the affected passageway. The inflator (40 1150) may include a body (1160) a plunger assembly (1200) and locking features (1230 1231) that selectively secure the position of the plunger assembly relative to the body by moving along a path that is transverse to a longitudinal axis defined by the plunger assembly.
