Abstract
Systems, methods, and devices allow intravascular or percutaneous mapping, orientation and/or ablation, in bodily cavities or lumens. A device includes elongate members, moveable between an unexpanded configuration and an expanded or fanned configuration. The elongate members form a stack in the unexpanded configuration to fit through a catheter sheath. The elongate members follow respective arcuate or curvilinear paths as advanced from the sheath into the bent or coiled stack configuration, adopting volute, scroll or rho shapes, and may be nested. The elongated members are fanned or radially spaced circumferentially with respect to one another into the expanded or fanned configuration. Transducer elements carried by elongate members sense various physiological characteristics of or proximate tissue, and/or may apply energy to or proximate tissue. The elongate members are rotatable in groups or as a group in the expanded configuration. The device is retractable.
