摘要： A medical device includes a shaft including a central lumen configured to direct a flow of fluid through the shaft, and an electrode positioned at a distal portion of the shaft. The electrode includes an electrode lumen in fluid communication with the central lumen, and the electrode lumen is configured to receive the flow of fluid from the central lumen. The electrode also includes one or more channels angled relative to the electrode lumen, and the one or more channels are in fluid communication with the electrode lumen to receive the flow of fluid from the electrode lumen. The one or more channels are configured to divert the flow of fluid from the electrode lumen toward one or more outlets laterally offset from the electrode lumen.
