OPEN-IRRIGATED ABLATION CATHETER WITH TURBULENT FLOW

摘要

According to an embodiment of a method for cooling an open-irrigated ablation electrode, pressurized fluid is delivered from a fluid lumen of a catheter body into an ablation electrode. Fluid flow in the fluid lumen is generally laminar. The generally laminar fluid flow is transformed from the fluid lumen into a turbulent fluid flow within the ablation electrode. The pressurized fluid with turbulent fluid flow is delivered through irrigation ports of the ablation electrode.
