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 link member with wear crutch, the linking member including a pair of side arms and at least one integrally formed loop end portion, the inner surfaces of the side arms and loop end portion defining a friction surface, the inner surfaces of the respective side arms diverging from one another away from the loop end portion and the wear crutch including two curved surfaces arranged as an outer and an inner surface, the outer surface to abut a surface of the linking member in a loop end portion and the inner surface presenting a wear surface for the linking member, and whereby the outer and inner surfaces intersect one another at opposite ends of the wear crutch along common edge portions, and a pair of substantially parallel locating arms adapted to abut respective surfaces of the linking member such that said common edge portions each engage an adjacent arm in a substantially flush manner when the wear crutch is seated on the linking member.

Abstract: The invention provides a golf club, generally indicated by reference numeral (10). The golf club (10) includes a shaft (14) and club head (12) connected to the shaft (14). The golf club (10) further includes means defining a reflective surface (16) positioned so that when a user of the golf club (10) addresses a ball an intended target towards which a said ball is to be struck is visible in the reflective surface (16). The golf club also includes level indicators (40, 50), in the form of spirit levels, mounted on the head (12) to permit a user to determine when the head (12) is in a desired horizontal orientation when addressing a ball with the golf club (10). The level indicators (40, 50) is positioned to form an alignment aid, the alignment aid including parallel markings (38) on the reflective surface (16) in register with corresponding ends of the spirit levels (40,50).

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.

Abstract: An athletic shoe sole comprising a midsole and an outsole. The midsole has a longitudinally concave shaped ball portion which is thinnest along a transverse metatarsal line, such that a longitudinal concavity is formed facing downwardly and crossing the entire width of the ball portion of the midsole. The outsole has a longitudinally convex shaped ball portion which is thickest along the transverse metatarsal line, such that a longitudinal convexity is formed facing upwardly and crossing the entire width of the ball portion of the outsole. The longitudinally convex shaped ball portion of the outsole has numerous conical shaped hollow tread members aligned in a plurality of transverse rows, and two longitudinally elongated edgewise non-hollow tread members each having a plurality of transverse grooves.
