Abstract
Medical devices that provide for selected curve deflection in multiple planes such that three-dimensional shapes can be formed in the medical devices by placing a pull wire extending through the catheter in tension, as well as methods of manufacturing and using the medical devices. The medical devices may include selected portions in which the location of the pull wire changes circumferentially and/or radially to provide for the selected curve deflection. The medical devices may include, in addition to, or in place of changes in pull wire location, selected portions having exhibiting changes in rigidity to provide for the selected curve deflection.
