Patent attributes
An inflation device useful for inflating a balloon provided with a surgical instrument, such as a balloon sinus dilation instrument. The inflation device includes a syringe, a connector, and mechanical pressure indicator. The syringe includes a plunger slidably disposed within a barrel. The connector is configured to fluidly connect an outlet of the syringe with a surgical instrument balloon in establishing a closed inflation system between the syringe and an interior of the balloon. The pressure indicator is associated with the syringe and is configured to transition from a non-alert state to an alert state when a pressure of the inflation system has reached a predetermined level. In some embodiments, the inflation device is characterized by the absence of a pressure gauge.
