Devices, systems and methods are disclosed for the formation of an arteriovenous fistula. Embodiments include catheter apparatus including an ablation element for creating and/or modifying the fistula. The devices, systems and methods can be used to treat patients with one or more numerous ailments including chronic obstructive pulmonary disease, congestive heart failure, hypertension, hypotension, respiratory failure, pulmonary arterial hypertension, lung fibrosis and adult respiratory distress syndrome.

An intervertebral connection system wherein the bone anchor has a helical configuration.

A system for improving the efficiency of a belt-driven system is provided. The system is particularly adapted for retrofitting tensioners onto existing belt-driven machines or to incorporate a tensioner into an the existing design of a belt-driven machine with limited changes to the specifications of the existing design. The system includes a motor driving a belt that drives a pulley. The pulley drives a shaft or other element of the system. A tensioner is provided for tensioning the belt to impede slippage between the belt and the pulley. The tensioner is connected to the motor and a frame of the system via a mounting bracket that includes a first leg and a second leg having a plurality of mounting holes adapted to cooperate with mounts on the motor and a connector of the tensioner. In one embodiment, the mounting holes of the second leg are laterally offset from one or more mounting holes of the first leg. Additionally, in one embodiment, the mounting bracket is configured so that the mounting holes in the first leg are positioned to form an array of rows and columns, and the mounting holes in the second leg are positioned to form a separate array of rows and columns.

A stabilization system for the spine that includes an elongated member, preferably an elastic cord, and a plurality of attachment mechanisms, preferably lamina hooks. The stabilization system is configured to extend across a plurality of spinal motion segments to dynamically couple the motion segments in a manner that places the system in tension to apply a compression force to the posterior of the spine. The system and method may have particular application after a laminectomy or laminoplasty procedure.

The present invention relates to a ratcheting unit enabling for securing cargo particularly for tightness in order to secure a load of cargo quickly and safely. Typically these ratcheting straps feature a first end with one length of strap secured to the first end via a bolt, and the other length of strap is fed through a ratcheting cylinder. The ratchet allows the user to hook the straps on the distal ends to a secure anchor point, i.e. the side of a trailer. The straps are pulled taught, the loose strap is fed through the ratcheting cylinder and the ratchet handle is used to tighten the slack in the strap, bringing the strap to a higher tension than what one could easily achieve without the aid of a ratchet to hold the tension and provide leverage for taking in further slack.

An improved vehicle is provided that has an excellent obstacle overcoming ability, including stair climbing. The apparatus comprises a frame, and a pair of endless track units positioned on opposite sides. Each track unit has a plurality of telescoping rollers in contact with the inner track surface configured to guide the track around a track pathway, and move vertically when navigating over obstacles. Each track unit further comprises a drive assembly in contact with the track, and movable between a raised position and a lowered position, such that movement of the drive assembly also operates to provide track tension.

The configuration comprises a carrier equipping an ejection plate on the front for ejecting the bundled-paper sheet material P and equipping a plurality of cutout parts, which are open in their top parts, at a predetermined interval on both the left and right sides; and a drive transmission unit being equipped by a plurality of drive rollers, each of which comprises a plurality of bosses in a predetermined interval on a single circumference around the rotation center thereof, in a predetermined interval on both the left and right sides of the bundled-paper sheet material transport path, wherein a drive force is transmitted by allowing bosses of each drive roller, which rotates by receiving a drive force from a drive source, engage in the respective cutout parts of the carrier sequentially, thereby allowing the carrier travel in the front and back directions of the bundle transport path.

A system for forming a looped suture is provided. The system includes a suture supply assembly configured for supplying thread, a flipper gripping assembly configured for forming a loop in the thread, a carriage assembly configured for advancing the thread through the forming process, and a welding assembly configured for securing the loop in the thread.

A meshless foil stencil frame removes all the components of mesh mounted frames and associated issues and mechanically attaches the foil to an aluminum frame by way of pre-cut tabs. Tension is applied by either pulling on all four sides of the frame and then placing a spacer at each corner to maintain the displacement of each frame member or locking the corners and placing a displacement insert between frame and foil. This displacement in turn applies pressure on a foil which is held firm at each of the four edges and therefore creates tension on the foil.

The device is comprised of a generic cushioned shock absorbing type material orthotic support structure attached to the brace layer. The orthotic support structure comprises a raised midsole that tapers at the anterior end and transitions into a heel cushion which surrounds the bottom of the wearer's heel at the posterior end. The orthotic support structure continues to the heel, where it provides a cup to form to the shape of the heel.

An arrangement of fenders nested together for compact storage, the fenders including two or more cylindrical bodies having a cavity accessed through the fender top, the fenders being similar shape but graduated in size such that the cavity of a larger fender tensionally receives the next smaller sized fender, the outer diameter of the smaller fender equal to the inner diameter of the larger fender cavity. A fender has a rigid inner core surrounded by a compressible shell made of foam or similar material. The inner core has attachment points for a rope or line. The smallest nesting fender in the set has a cavity diameter sized to fit a commercially-available, off-the-shelf fender. The fenders may be separated and deployed at individual locations on a vessel, or kept together and deployed as a single fender capable of absorbing a greater impact than any of the fenders individually would absorb.
