The spines further comprising a first surface being outward from the longitudinal axis; one or more contact pads affixed to a portion of the first surface of the spine; and one or more flexible circuits disposed over respective ones of the one or more contact pads, the one or more flexible circuits each comprising an electrode and an inductive coil as one unit.

Abstract: Various examples of an ablation end effector are shown and described with two balloons independently inflatable so that a distal balloon can be used to ensure stability of the second balloon for electrical ablation in a beating heart. Methods and techniques to operate the ablation end-effectors are also described.

Abstract: The distal end of the catheter can be constructed to include one or more features to provide strain relief to wiring of multiple single axis sensors. In some examples, the multiple single axis sensors and associated wiring can be manufactured over a flexible tube that can be placed over a movable support member. In some examples, wiring can be wound an increased number of consecutive traverse turns on a distal and/or proximal side of a single axis sensor, and a shrink sleeve may be positioned over the traverse turns. In some examples a wire shield transition point can be positioned on a straight portion in a proximal direction to the distal portion of the catheter.

Abstract: A heavy duty, high efficiency jumper cable system designed to deliver 250 to 3,800 amps with minimal loss by transmitting current from a source through a cable/terminal connector through a heavy duty cable to a second cable/terminal connector and then to a discharge point. The cable/terminal connectors include an electrical harness that minimizes power loss by direct contact between the cable delivering current to the cable connector and a pair of electric contacts, each member of which is positioned in an end of a support. The system is uniquely, but not specifically adapted for use with electrical systems associated with diesel powered vehicles and equipment.
