  • Patent number: 8882762
    Abstract: A transmural ablation device is provided to achieve endocardial and epicardial ablation at the same site but directed from the inner and outer surfaces of the heart to create a transmural lesion. By ablating from both sides of the heart tissue, it is possible to increase the depth of the lesion created and to increase the likelihood of a transmural lesion. Embodiments pertain to techniques to align the endocardial and epicardial ablation elements and techniques to position and move the endocardial and epicardial ablation elements along a predefined linear, curvilinear, or circular path. The ability to bring the epicardial and endocardial elements more closely or firmly with the underlying tissue is important in creating optimal lesions. Magnetic force attracts the epicardial and endocardial elements.
