Pulse spray catheter. To increase the efficiency of drug thrombolysis, pulse spray catheters are often used. The technique involves embedding the catheter within the clot and intentionally obstructing the catheter end hole with a guidewire. When the fibrinolytic agent is injected, it is forced out through the catheter sideholes in jets and permeates the clot. With this method, a larger surface area of clot is exposed to the fibrinolytic agent.
