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 the 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 or ablation, or combinations thereof in bodily cavities or lumens. A device includes a plurality of elongate members which are moveable between an unexpanded configuration, a bent or coiled stack configuration and an expanded or fanned configuration. The elongate members form a stack arrangement 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. Transducers carried by elongate members may sense various physiological characteristics of or proximate tissue, for instance temperature, and/or may apply energy to or proximate tissue, for example to perform ablation. The device is retractable.

Abstract: A medical device system may include transducers and a structure on which the transducers are located. The structure may include at least a first portion of each elongate member of a plurality of elongate members. Each respective set of a plurality of sets of one or more of the transducers may be located on a respective one of the plurality of elongate members. The structure may be selectively moveable between a delivery configuration in which the structure is sized to be percutaneously deliverable to a bodily cavity and a deployed configuration in which the structure is sized too large to be percutaneously deliverable to the bodily cavity. The second portion of each elongate member of the plurality of elongate members may be arranged in a helical configuration or a twisted, non-helical configuration including at least 360 degrees of rotation when the structure is in the delivery configuration.
