Abstract: Embodiments of systems, methods, and catheters for delivery of treatments to a blood vessel (e.g., fistula formation) using one or more catheters. Embodiments of the catheter or catheter system may include a first catheter including a first body, an electrode mounted to the first body, and a first array of magnets mounted to the first body, and a second catheter including a second body, a second array of magnets mounted to the second body, and a flexible backstop extending longitudinally along the second array of magnets. In embodiments, the presently disclosed catheters and catheter systems may provide endovascular fistula formation treatment that provide improved catheter flexibility.

Abstract: A catheter for use in a system for forming a fistula, the catheter including a catheter body, and a segmented backstop coupled to the catheter body and configured to receive a fistula-forming element, wherein the segmented backstop comprises at least a proximal segment and a distal segment, independently articulable relative to one another.

Abstract: Energy infrastructure systems are contemplated with a raceway with first and second rails or other rows of multiple connection points, first and second cover plates positionally affixed with respect to the first and second rails, a buss extending along at least a portion of the raceway. A first and second current carrying structure is electrically coupled to the buss, where each is configured to carry electrical current through a passageway in a cover plate. A method for updating an electrical infrastructure system, comprising affixing a second distribution hub to the second cover plate, coupling the second distribution hub to draw power from the buss, and moving or replacing the first cover plate with a third second cover plate, such that the third cover plate occupies a different position or length along the raceway. Extruded aluminum modules and hubs for such systems are further contemplated.

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: An apparatus for performing a medical procedure and, in particular, an aortic valvuloplasty, in a vessel for transmitting a flow of fluid. The apparatus comprises a shaft, an inflatable perfusion balloon supported by the shaft and including an internal passage for permitting the fluid flow in the vessel while the perfusion balloon is in an inflated condition, and a valve for controlling the fluid flow within the passage. The valve may be connected to the shaft, or may comprise an elongated tube partially connected to the balloon. The balloon may comprise a plurality of cells in a single cross-section, each cell including a neck, and the valve may be positioned in a space between the shaft and the necks for controlling the fluid flow within the passage. A connector may also be provided to control the position of the valve.

The apparatus includes an inflatable perfusion balloon including an internal passage for permitting the fluid flow in the vessel while the perfusion balloon is in an inflated condition, the balloon including a plurality of cells in a single cross section and a covering for at least partially covering the cells. A valve associated with the balloon controls the fluid flow within the passage, the valve being arranged external to the passage. The valve may form a tubular extension of the covering, or may be separate from the covering, and may comprise flaps. A spiral covering may also form the valve.

Abstract: Improvements in a modular electric charging apparatus are disclosed. The modular electric charging apparatus provides a universal base system that can be used to install an electrical power system. The universal base system allows cabinets provided from different manufacturers to be connected by electrical wiring into their unique cabinets. A below grade structure of an open frame structure is used for setting and casting concrete around the open frame. The open frame is set at a level with a desired finished surface with a trench canal and the concrete can be poured into both sides of the open frame. The modular electric charging apparatus also uses a canal that extends from a base of the cabinet. The canal is easily cut to a length or multiple canals can be placed in series for extending the length. Buss bars are set and are secured in an insulated spacer within the canal for use in connecting to a plurality of above ground charging stations.

Abstract: A valve prosthetic implant for treating a vein or other blood vessel includes a tubular, expandable anchoring frame extending from a proximal end to a distal end of the implant, a valve seat formed at or near the middle of the anchoring frame, an expandable ball disposed within the lumen of the anchoring frame, and a ball retention tether attached to the expandable ball and to the valve seat and/or the anchoring frame. The anchoring frame may include a cylindrical proximal portion at the proximal end, a cylindrical distal portion at the distal end, an inwardly angled inlet portion between the cylindrical proximal portion and a middle of the anchoring frame, and an inwardly angled outlet portion between the cylindrical distal portion and the middle of the anchoring frame.
