1. An indeflator for inflating a therapeutic balloon to a desired pressure comprising:
a barrel having an interior surface defining an interior chamber configured to receive fluid, and an outlet in fluid communication with the interior chamber; a plunger sealingly engaging the interior surface of the barrel, wherein the plunger is selectively movable linearly within the interior chamber for dispensing fluid through the outlet of the barrel; a coarse inflation control assembly including a coarse inflation actuator selectively rotatable about a coarse rotational axis to impart linear movement of the plunger in the interior chamber for dispensing fluid through the outlet of the barrel, wherein the coarse inflation control assembly has an inverse coarse inflation rate defined as a ratio of angular displacement (degrees) of the coarse inflation actuator about the coarse rotational axis to linear displacement (mm) of the plunger in the interior chamber imparted by the angular displacement of the coarse inflation actuator; and a fine inflation control assembly including a fine inflation actuator selectively rotatable about a fine rotational axis to impart linear movement of the plunger in the interior chamber for dispensing fluid through the outlet of the barrel, wherein the fine inflation control assembly has an inverse fine inflation rate defined as a ratio of angular displacement (degrees) of the fine inflation actuator about the fine rotational axis to linear displacement (mm) of the plunger in the interior chamber imparted by the angular displacement of the fine inflation actuator, wherein the inverse fine inflation rate is greater than the inverse coarse inflation rate. |
