摘要： Improved mapping and ablation procedures and corresponding devices are provided. A variety of methods and apparatuses can be used for the treatment of cardiac arrhythmias by identifying the location of an arrhythmia source and ablating that source. The methods and apparatuses can provide an improved means of electrical mapping of the heart to identify the location of the arrhythmia source and advancing an ablation electrode to that location so that it may be ablated.

摘要： Various catheters with expandable and contractible fluid pathways extending therethrough, and methods of use, are provided herein. In an exemplary embodiment, a catheter is provided with an elongate body having an electrode at the distal end thereof. One or more expandable members or wings can extend between the electrode and the distal end of the elongate body. The catheter can also include an actuator extending therethrough and coupled to the electrode such that movement of the actuator is effective to advance and retract the electrode, thereby moving the one or more expandable members between a collapsed configuration and an expanded configuration. The catheter can also include a fluid sealed lumen formed therein and configured to receive fluid and to deliver fluid to one or more pathways formed in the electrode. The actuator can extend through the fluid sealed lumen, however it can be fluidly separated from the lumen. The fluid sealed lumen can be configured to expand and collapse with movement of the electrode, while allowing movement of the actuator therethrough.

摘要： Various catheters are provided herein for recording, mapping, and/or ablating target tissue to reduce or eliminate unwanted electrical impulses. In one embodiment, a catheter can have a handle, an elongate body, and an end effector. The end effector has expanded and contracted configurations and can rotate about the elongate body. A plurality of electrodes can also be disposed on the end effector for recording, mapping, and/or ablating target tissue surrounding the catheter. The handle can guide the end effector through transitioning between the configurations and rotating about the elongate body.

摘要： Improved ablation procedures and exemplary catheters for use with such procedures are provided. In one example, high quality homogenous lesions with well-defined borders can be created by introducing into a patient body a catheter that includes an electrode that is mounted on a distal end of the catheter, positioning the electrode to be in contact with tissue to be ablated such that at least 65 percent of an exposed distal surface area of the electrode is in contact with the tissue to be ablated, and applying electrical energy to the electrode sufficient to create an ablation lesion in the tissue.
