Structures for supporting diagnostic or therapeutic elements in internal body regions
 Elongated spline members are threaded through a hub to form depending spline legs. In one embodiment, the spline members are threaded through a puncturable material on the hub. In another embodiment, the spline members are threaded through a slotted hub, which is then encapsulated by a sealing, elastomeric material. In another embodiment, multiple spline members are looped and woven together beyond a distal end of the hub, and the distal end of the hub serves to exert a force that maintains the woven relationship of the spline members. The spline legs, which radiate from the hub, preferable carry one or more diagnostic or therapeutic elements, such as electrodes. Preferably, a base constrains the terminal ends of the spline legs in a normally expanded geometry between the hub and base.
