Abstract: A catheter sheath device may include an elongate member and a moveable member. The elongate member may include a first lumen, and the moveable member may include a second lumen. The moveable member may be physically coupled to a portion of the elongate member to permit relative movement therebetween. A first relative movement between the moveable member and a portion of the elongate member may cause the second lumen to be positioned at a first location that permits delivery of at least a portion of a catheter into the second lumen but not into the first lumen from the second lumen. A second relative movement between the moveable member and the portion of the elongate member may cause the second lumen to be positioned at a second location that permits delivery of the at least the portion of the catheter through both the second lumen and the first lumen.

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.

Abstract: Medical systems are disclosed which may include an elongate shaft member and a plurality of steering lines operable to cause bending of the elongate shaft member via movement of at least one of the steering lines. A respective second end portion of a first proximal steering line may terminate at a first proximal termination portion of the elongate shaft member, and a respective second end portion of the first distal steering line may terminate at a first distal termination portion of the elongate shaft member. The elongate shaft member may be formed of materials of different hardness to provide preferential bending in desired directions.

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.
