An inflation syringe configured to allow a medical practitioner to selectively provide a desired amount of inflation pressurization during a medical procedure to inflate a medical instrument, the inflation syringe comprising: a barrel defining an inner lumen and being adapted to hold a desired inflation pressure; a plunger configured to be received within the inner lumen of the barrel to increase pressurization within the barrel; a sensor apparatus for sensing inflation pressurization within the barrel; and a display linked to the sensor apparatus, to display the inflation pressurization detected by the sensor apparatus within the barrel, wherein the display includes a numeric display which is adapted to provide a numeric indication of a current inflation pressurization within the barrel and a plurality of non-numeric indicia (24, 51) which are actuatable to provide a non-numeric representation of the current inflation pressurization, characterized in that: the display is mounted to the exterior of the barrel and is linked to the sensor apparatus when the display is mounted to the barrel; and wherein the plurality of non-numeric indicia are actuatable in a progressive manner such that non-numeric indicia representing values less than the current inflation pressurization value remain actuated as the pressurization increases; and wherein the non-numeric indicia are adapted to simultaneously provide a non-numeric representation of a second pressurization value that is different from the current inflation pressurization value and wherein the second pressurization value may correspond to any of the non-numeric indicia. a barrel defining an inner lumen and being adapted to hold a desired inflation pressure; a plunger configured to be received within the inner lumen of the barrel to increase pressurization within the barrel; a sensor apparatus for sensing inflation pressurization within the barrel; and a display linked to the sensor apparatus, to display the inflation pressurization detected by the sensor apparatus within the barrel, wherein the display includes a numeric display which is adapted to provide a numeric indication of a current inflation pressurization within the barrel and a plurality of non-numeric indicia (24, 51) which are actuatable to provide a non-numeric representation of the current inflation pressurization, characterized in that: the display is mounted to the exterior of the barrel and is linked to the sensor apparatus when the display is mounted to the barrel; and wherein the plurality of non-numeric indicia are actuatable in a progressive manner such that non-numeric indicia representing values less than the current inflation pressurization value remain actuated as the pressurization increases; and wherein the non-numeric indicia are adapted to simultaneously provide a non-numeric representation of a second pressurization value that is different from the current inflation pressurization value and wherein the second pressurization value may correspond to any of the non-numeric indicia. the display is mounted to the exterior of the barrel and is linked to the sensor apparatus when the display is mounted to the barrel; and wherein the plurality of non-numeric indicia are actuatable in a progressive manner such that non-numeric indicia representing values less than the current inflation pressurization value remain actuated as the pressurization increases; and wherein the non-numeric indicia are adapted to simultaneously provide a non-numeric representation of a second pressurization value that is different from the current inflation pressurization value and wherein the second pressurization value may correspond to any of the non-numeric indicia.
