摘要： According to one aspect, an instrument may include a sheath having a distal end. The instrument also may include a fluid cannula at the distal end of the sheath. The instrument also may include a cutting electrode at the distal end of the sheath. At least one of: (i) an exterior surface of the fluid cannula, and (ii) a cutting electrode surface that faces the exterior surface, is longitudinally slidable along the other of the exterior surface and the cutting electrode surface during movement of at least one of the cutting electrode and the fluid cannula relative to the other of the cutting electrode and the fluid cannula.

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.
