1. A balloon catheter, comprising:
- a proximal handle assembly;
a catheter attached to the handle assembly and configured to receive inflation fluid from the handle assembly; and
a balloon at the distal end of the catheter and configured to receive inflation fluid from the catheter;
wherein the handle assembly comprises;
a first assembly including an actuator connected to a reservoir for releasing pressurized fluid from the reservoir; and
a second assembly having an inflation fluid chamber, the second assembly being connected to the first assembly to receive pressurized fluid from the first assembly and connected to the catheter to deliver inflation fluid to the catheter in response to receipt of pressurized fluid,wherein the actuator is configured to (a) move from a first position to a second position causing release of pressurized fluid from the reservoir and (b) move from the second position to the first position to stop flow of the pressurized fluid from the reservoir.

Abstract
An apparatus and method for ejecting fluid from a fluid delivery system. The fluid delivery system has a pneumatic assembly that when triggered injects gas into a hydraulic assembly, which in turn ejects fluid through an external interface. An electronic interface displays various measurements, for example, how much fluid has been ejected and if the hydraulic system is closed the pressure of the system. The pneumatic assembly can also be depressurized such that fluid can reenter the hydraulic assembly through the external interface.
