  • Patent number: 9962530
    Abstract: A dilation catheter system 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, a dilator, a guide catheter, and an inflator. The dilation catheter may be positioned between the dilator and the inflator. The guide catheter is configured to guide the dilator into the affected passageway. The inflator may then be actuated to transfer fluid from the inflator, through the dilation catheter, and into the dilator. The transfer of fluid may inflate the dilator to an expanded state to open or dilate the affected passageway. The inflator may include a body, a plunger assembly, and locking features 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.

  • Publication number: 20180049767
    Abstract: A surgical instrument including a shaft including a distal portion and an articulatable portion is disclosed. The articulatable portion, positioned proximal to the distal portion, includes a plurality of joint members. A first articulation cable extends through each first channel of each of the plurality of joint members and a second articulation cable extends through each second channel of each of the plurality of joint members to the distal portion. The first and second articulation cables are transitionable between: (i) an unlocked state, where the first and second articulation cables are free to translate distally and proximally and the plurality of joint members are slidable relative to one another to pivot the distal portion away from a longitudinal axis, and (ii) a locked state, where translation of the first and second articulation cables is locked, causing a position of the distal portion relative to the longitudinal axis to be locked.
