Abstract
A power injection catheter for high flow rate delivery of fluids. The power injection catheter may include a pressure relief mechanism for preventing overpressurizing within the lumen of the catheter. The pressure relief mechanism may be configured to prevent sudden pressure build-up inside the catheter lumen by absorbing, buffering or releasing pressure inside the lumen during pressure spikes. The power injection catheter may also take the form of a multi-lumen catheter capable of simultaneous infusions of a single fluid through two or more of the lumens in the catheter.
