摘要： A catheter for anchoring an electrode in a coronary sinus includes an elongate catheter body adapted to be inserted into a coronary sinus and at least one electrode on the catheter body. The elongate catheter body also includes at least one anchor movable between an undeployed configuration and a deployed configuration. When the anchor is in the undeployed configuration, the catheter may be introduced into and removed from the coronary sinus. When the anchor is in the deployed configuration, the anchor engages a tissue surface of the coronary sinus to inhibit movement between the catheter body and the coronary sinus, preferably without completely occluding the coronary sinus. The anchor may be a section of the catheter body having an expandable axial cross-section, an expandable member mounted on the catheter body, one or more wire anchors, or a flexible section of the catheter body.

摘要： A system for providing irrigation fluid during ablation of tissue includes a catheter, an electrode assembly, at least one thermal sensor adapted to be connected to the catheter, and a control system. The electrode assembly is adapted to be connected to an ablation generator. The thermal sensor is adapted to be operatively connected to an electronic control unit (ECU). The ECU receives as an input temperature measurement data from the thermal sensor; determines a power delivery rate value for the ablation generator responsive to the temperature measurement data; and outputs the power delivery rate value. The control system also delivers irrigation fluid to the irrigated catheter at a first flow rate in a first time period and at a second flow rate in a second time period that is temporally after the first time period. The second flow rate is at least half of the first flow rate.

摘要： Ablation electrode assemblies having a longitudinal axis include an electrode core member; an electrode shell; and an irrigant distribution element. The electrode core member comprises a thermal insulator and has a first end; a second end; and at least one irrigation passageway. The electrode shell comprises an electrically conductive material, defines an inner volume, and has a first end; and a second end. The second end of the electrode shell is configured for connection to the first end of the electrode core member. The electrode shell is sufficiently flexible for deflection of the distal end of the electrode shell relative to the longitudinal axis of the ablation electrode assembly. The irrigant distribution assembly comprises a first end; and a second end, wherein the second end of the irrigant distribution element defines a circumferential irrigation port between the irrigant distribution element and the electrode core member.
