摘要： Device, system and method for evaluating the effectiveness of tissue ablations of a heart of a patient. The tissue is clamped between a pair of opposing jaws. A portion of the tissue is ablated at a first generally linear position on the tissue by applying ablative energy to two of a plurality of elongate electrodes, each of the two of the plurality of elongate electrodes being coupled in opposing relationship to each other and the pair of opposing jaws, respectively. An effectiveness of the ablation is sensed at a second generally linear position on the tissue with at least one of the plurality of elongate electrodes positioned on one of the pair of opposing jaws. The second linear position on the tissue is laterally distal to the first linear position on the tissue with respect to the atrium of the heart.

摘要： Some embodiments of the invention provide a system for occluding a left atrial appendage of a patient. Some embodiments of the system can include a ring occluder that can be positioned around the left atrial appendage and a ring applicator to position the ring occluder with respect to the left atrial appendage. One embodiment discloses a method of accessing endocardial surfaces of the heart through the atrial appendage. Additional embodiments of the invention provide a clip occluder that can be positioned around the left atrial appendage. A clip applicator can position the clip occluder with respect to the left atrial appendage.

摘要： An example system for use in ablating target tissue includes memory configured to store anatomical and/or physiological information of a patient and processing circuitry communicatively coupled to the memory. The processing circuitry is configured to, based on the anatomical information and/or the physiological information, determine ablation parameters, the ablation parameters including a suggested positioning of at least energy delivery element of at least one catheter and/or an amount of energy to be delivered via the at least one energy delivery element to the target tissue during ablation. The processing circuitry is configured to output, for display, a representation of at least one of a suggested positioning of the at least one energy delivery element during the ablation, a representation of the target tissue, or a representation of the predicted tissue volume that will be ablated after delivery of ablation energy.
