Fluid management system for coronary intervention
First Claim
1. An injection system, comprising:
- a first power-actuated injector adapted to inject a first fluid through a first fluid line having a distal end;
a second power-actuated injector adapted to inject a second fluid through a second fluid line having a distal end;
a fitting having first and second inputs and an output, the distal ends of the first and second fluid lines being connected to the first and second inputs of the fitting, respectively; and
a medical device connected to the fitting output.

Abstract
A fluid injection system is disclosed. The system is adapted to employ first and second injectors which may sequentially, or simultaneously, inject first and second fluids into a patient via a catheter. The first and second injectors may be power actuated. The actuation of the injectors may be controlled via a controller of the system. The user may be provided with an operator interface module to enable the control of the system to be affected during operation. A separate waste line may be provided to drain the system effectively and efficiently. A pressure sensor may be provided proximate the catheter to reduce pressure signal wave dampening and fluid waste.
