Abstract: A method of limiting an inflation system pressure for dilating a region of a patient’s nasal sinus passageways. The method includes grasping an inflation device. The inflation device includes a syringe including a plunger slidably disposed within a barrel, a connector for fluidly connecting an outlet of the syringe with a surgical instrument balloon, and a mechanical pressure indicator associated with the syringe, the mechanical pressure indicator including a housing and an indicator body disposed within the housing. The method also includes delivering the surgical instrument balloon to a patient’s paranasal sinus target area, operating the plunger within the barrel of the syringe to deliver pressurized fluid to the surgical instrument balloon, and transitioning the indicator body to extend outside of the housing when a predetermined inflation pressure of the surgical instrument balloon is reached.

Abstract: A stent (100) that is sleeved and radially expandable, and which in an expanded state provides a breathable, generally tubular structure sized and shaped for residence in a sinus or nasal cavity or passage, and in an unexpanded state has a cross-sectional diameter suitable for insertion into such cavity or passage. The sleeve limits expansion and outward pressure exerted by the stent and thereby can prevent or reduce the incidence of headache in patients, and can provide increased surface area for improved elution of drugs to nearby mucosal tissue.

Abstract: Aspects of the disclosure relate to pledget stimulation/recording electrode assemblies that are particularly useful for automatic periodic stimulation. Embodiments are compatible with nerve monitoring systems to provide continuous stimulation of a nerve during surgery. Disclosed embodiments include an electrode assembly having one or more electrodes rotatably supported by and positioned within a pledget substrate. The flexible pledget substrate conforms and fixates to bioelectric tissue to secure the electrode assembly in position, wrapped around the target tissue. In some embodiments, the pledget substrate includes two bodies, each including at least one electrode, the two bodies being selectively separable so that the bodies can be repositioned with respect to one another. The electrode assembly further includes a lead wire assembly including at least one insulating jacket positioned around a wire core.

Abstract: A sinus dilation instrument useful with a navigation system and including a handle, a rigid probe, a balloon, and an identifier device. The probe extends from the handle, forms a curved segment, and carries the balloon. The identifier device is programmed to generate a signal indicative of an instrument identification assigned to the instrument, and is a frontal, maxillary or sphenoid sinus instrument. The signal is formatted to be recognized by an IGS. Once connected, the IGS recognizes the instrument and can retrieve information indicative of a spatial location of the balloon, for example via an instrument tracking device. A surgeon can “plug and play” the sinus dilation instrument with the IGS to perform a procedure.

A trialing adaptor receives the proximal end of the lead and is removable when a trialing period is completed. A sheath encloses at least a portion of the lead and covers the fixation member. The sheath is configured to remain in place over the lead during the trialing period.

Abstract: Implants are placed in turbinate mucosal tissue using a surgical device having a proximal grip portion and a distal hollow sharp needle portion that is manipulated using the grip portion and inserted submucosally into mucosal turbinate tissue. One or more biodegradable, drug-eluting solid implants are disposed within the needle.

An actuator disposed within the device is used to deliver one or more of the implants from the needle into the mucosal turbinate tissue and submucosally bury at least one such tissue-engaging feature therein.
