    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.
