Abstract
An integrated inflation/deflation device provides easy, precise delivery of a small amount of fluid for proper inflation of a low volume surgical balloon and similarly provides easy and fast deflation of the balloon. A preferred embodiment includes a low volume syringe and large syringe mounted together within a housing. A port in the low volume syringe is in communication with the large syringe barrel. The low volume syringe plunger is controlled by a knob disposed on the housing. The large syringe is used to prime the surgical balloon system, including a catheter, and the low volume syringe delivers a precise, predetermined volume of fluid to inflate the balloon. The low volume syringe is also used to deflate the balloon. Preferably, indicia on the housing adjacent the knob direct the required rotation of the knob to deliver the correct volume of fluid to be injected to match a balloon of a given size and shape so that the balloon is properly inflated.
