  • Publication number: 20140114405
    Abstract: Medical devices and delivery systems for delivering medical devices to a target location within a subject. In some embodiments the medical devices can be locked in a fully deployed and locked configuration. In some embodiments the delivery systems are configured with a single actuator to control the movement of multiple components of the delivery system. In some embodiments the actuator controls the independent and dependent movement of multiple components of the delivery system.

  • Publication number: 20140058197
    Abstract: A tissue electrode assembly includes a membrane configured to form an expandable, conformable body that is deployable in a patient. The assembly further includes a flexible circuit positioned on a surface of the membrane and comprising at least one base substrate layer, at least one insulating layer and at least one planar conducting layer. An electrically-conductive electrode covers at least a portion of the flexible circuit and a portion of the surface of the membrane not covered by the flexible circuit, wherein the electrically-conductive electrode is foldable upon itself with the membrane to a delivery conformation having a diameter suitable for minimally-invasive delivery of the assembly to the patient.
