    摘要： Systems and methods support arrays of multiple electrodes in asymmetric pattern, either radially, or axially, or both. Radial asymmetry makes it possible provide localized density of electrodes. Axial asymmetry makes it possible to locate electrodes in a pattern that closely conforms to the irregular contours of an interior body cavity, like the heart. In a preferred embodiment, the systems and methods operate the multiple electrode arrays to form continuous lesion patterns.

    摘要： Structures having asymmetric mechanical properties provide enhanced ability to support therapeutic or diagnostic elements in contact with tissue in an interior body region. The support structure includes a first region, which exhibits a first mechanical property affecting tissue contact, and a second region spaced from the first region about the axis, which exhibits a second mechanical property, different than the first mechanical property, affecting tissue contact. In a preferred embodiment, the first and second mechanical properties correlate with stiffness of the respective first and second regions, with the first region being more flexible (i.e., less stiff) than the second region. The first region, due to its greater flexibility, is more conformal to tissue than the second region. The less flexible (i.e., more stiff) second region imparts greater force against the tissue to urge the more flexible first region toward intimate tissue contact. In a preferred embodiment, the more flexible first region carries at least one therapeutic or diagnostic element.

    摘要： Multiple electrode support structures have asymmetric geometries, either axially, or radially, or both. The asymmetric support structures are assembled from spline elements that extend between a distal hub and a proximal base. In one embodiment, the spline elements are circumferentially spaced about the distal hub in a radially asymmetric fashion, creating a greater density of spline elements in one region of the structure than in another region. In the same or another embodiment, the spline elements are preformed in an axially asymmetric fashion along their lengths, creating a different geometry in their distal regions than in their proximal regions.
