Pressure relief for a catheter balloon device
An inflation device for selectively inflating a balloon of a surgical instrument including a syringe, a connector, a mechanical pressure indicator, and a relief port. The syringe includes a plunger slidably disposed within a barrel. The connector fluidly connects an outlet of the syringe with a surgical instrument balloon to establish a closed inflation system between the syringe and an interior of the balloon. The mechanical pressure indicator is associated with the syringe and configured to transition from a non-alert state to an alert state when a pressure of the inflation system has reached a predetermined level. The relief port is associated with the mechanical pressure indicator and configured to relieve a pressure of the inflation system when the system at least reaches the predetermined level.
