Abstract: Systems, methods, and catheters for endovascular treatment of a blood vessel are disclosed. In one aspect, a catheter for endovascular treatment of a blood vessel. The catheter comprises a housing. The catheter further comprises a treatment portion. The catheter further comprises a fistula forming element. And the catheter further comprises an intravascular ultrasound imaging device.

Abstract: A system for forming a fistula, including a catheter including a catheter body, an electrode, one or more arrays of magnets, and a plurality of biasing rails. The one or more arrays of magnets are arranged longitudinally along the catheter body. The plurality of biasing rails extend along a length of the catheter body and are configured to radially arch away from the catheter body between a proximal point positioned proximal a first end of at least one array of magnets and a distal point positioned distal to a second end of the at least one array of magnets. The plurality of biasing rails bias the working site and the one or more arrays of magnets against a blood vessel wall. The plurality of biasing rails are joined by a connecting rail that laterally extends between the plurality of biasing rails.

Abstract: A delivery assembly includes a console including a vial containment region and a vial engagement mechanism extending from the console within the vial containment region. The engagement mechanism is configured to engage a vial assembly. The delivery assembly further includes a sled assembly removably coupled to the console at the vial containment region and a safety shield removably coupled to the console over the vial containment region such that the vial engagement mechanism and the sled assembly are encapsulated within the safety shield when the safety shield is coupled thereto. The sled assembly, the vial assembly, and the safety shield are configured to inhibit radioactive emissions from within the vial containment region.

Abstract: In the present disclosure, embodiments of dual-stage syringes are disclosed along with delivery systems incorporating the dual-stage syringes. Embodiments of the dual-stage syringes described herein include sleeved dual-stage syringes, turn-key dual-stage syringes and dual-stage syringes including one or more one-way valves.

Abstract: A pulsed welding regime includes a peak phase in which energy is added to an electrode and a weld puddle, and a molten ball begins to detach from the electrode, followed by a dabbing phase in which current is significantly reduced to place the ball in the weld puddle with addition of little or no energy. The resulting short circuit clears and the system proceeds to a background phase. The current in the dabbing phase is lower than the current during the background phase. The process may be specifically adapted for particular welding wires, and may be particularly well suited for use with cored wires. The dabbing phase allows for lower energy to be transferred to the sheath of such wires, and resets the arc length after each pulse cycle.

Abstract: An encoded clip generator comprises an input interface (402) for receiving source raw audio/video data from a media source (30). The source data comprises a series of complete video frames and a corresponding series of audio frames. The generator also includes an editor interface for receiving a clip start position and a clip end position. The generator includes a processor (410) and a memory (420) containing instructions for controlling the operation of the processor (410).

Abstract: Media objects such as film clips that have been stored for subsequent retrieval are represented in a display. In order to apply metadata tags to the objects, a user selects an individual media object from the display, and allocates a designated tag or set of such tags to the selected media object by placing a representation of the selected media object in a region of the display representing the designated tag or set of tags, whereby data relating to the selected media object is stored associating it with the tags so identified.

Abstract: A method and apparatus for the automatic composition of media articles is disclosed. Previous attempts to do this have involved the manual production of a detailed framework listing the types of media elements that might be inserted into the slots specified in that framework and the subsequent selection of media elements for those slots. The present invention improves upon this by associating metadata (51) with the media elements in a content store, which metadata includes relationship data indicating how what is portrayed by that media element relates to what is portrayed by one or more other media elements. Because relationship metadata is included media articles can be generated automatically with the need for the production of a detailed framework describing that media article.

Abstract: A mixing control system for elastomeric materials is described that includes a mixer housing forming a mixing chamber therein for receiving said elastomeric materials; at least one rotatable mixing means in the chamber; a dynamometer coupled to and driving said rotatable mixing means; torque sensing means for detecting torque exerted by the mixing means; said sensing means providing a torque signal level for controlling said mixing means; voltage-to-frequency conversion means for processing signal in which the pulse frequency varies in correspondence to the amplitude of the signal level; pulse counting means for continuously and cumulatively counting the pulses of said pulse signal; display means for displaying the count of said pulse counting means as the value of the integral of said signal level with respect to time; and control responsive means automatically responsive to a predetermined integrated value of said display means for controlling the total mixing energy input to the mixing control system.
