Gore gains FDA approval for first deep venous stent indicated for the IVC and iliofemoral veins

W. L. Gore & Associates, Newark, Delaware, announced on January 6, 2026 that the U.S. Food and Drug Administration has approved the GORE VIABAHN FORTEGRA Venous Stent for the treatment of deep venous disease in the inferior vena cava (IVC), iliac, and iliofemoral veins. The device is the first stent approved in the United States for the IVC and iliofemoral indication, and previously received FDA Breakthrough Device designation.

The FORTEGRA Venous Stent (formerly the GORE VIAFORT Vascular Stent) consists of an open-structure, self-expanding wire-wound nitinol frame and an expanded polytetrafluoroethylene (ePTFE) polymer lattice. The combination is designed to balance conformability to the natural venous anatomy with compression resistance throughout the entire device length, while the wound nitinol architecture supports fracture resistance under the dynamic mechanical loading characteristic of large-vein anatomy.

Approval was supported by an international pivotal trial that evaluated 89 patients with deep venous disease across the IVC, iliac, and iliofemoral veins. The device met its primary safety and effectiveness endpoints and demonstrated patency, freedom from clinically driven reintervention, and safety performance consistent with a first-line venous stent indication.

W. L. Gore & Associates is a privately held global manufacturing company founded in 1958 and headquartered in Newark, Delaware. Its medical products division supplies cardiovascular, vascular, structural heart, and surgical solutions in more than 50 countries and has served the deep venous disease space through prior peripheral and arteriovenous platforms.

One Minute Mentor: Transformation behavior of Austenite

The transformation behavior of retained austenite in M2 steel was examined under varying tempering conditions. The steel was initially subjected to interrupted quenching at 105 °C (225 °F), a process that elevated the retained austenite content to approximately 55 vol %, compared to the typical 25 vol % observed after direct quenching to room temperature. This was followed by tempering at 565 °C (1050 °F), without intermediate cooling. Results indicated that double tempering was significantly more effective than single tempering at transforming retained austenite under these conditions. Furthermore, repeated tempering cycles accelerated the complete transformation of retained austenite, achieving full conversion in a shorter total processing time than single-stage tempering.

NUTEC Bickley secures major contract for advanced ceramic core sintering kiln

NUTEC Bickley, Monterrey, Mexico, announced that it has been awarded a contract to supply a four-car shuttle kiln to a leading global energy technology company. The kiln will support sintering of ceramic cores at the customer’s investment casting facility, with firing cycles ranging from 20 to 80 hours, depending on the core specifications.

The gas-fired shuttle kiln is engineered to operate at temperatures up to 2010°F (1100°C) and features a twin-deck kiln car setting. Each car offers setting dimensions of 47 inches long by 63 inches wide by 34 inches high (1.19m x 1.59m x 0.87m), delivering a total effective load volume of 230 cubic feet (6.55m³) across all four cars. The kiln is designed to handle an average total product weight of 970 pounds (440 kg).

Twelve individually controlled high-velocity nozzle-mix burners—firing in a staggered sequence above and below the load—enable optimal heat transfer and temperature uniformity. Each burner includes automatic ignition and a safety system.

The kiln incorporates NUTEC Bickley’s proprietary IMPS® combustion control system, which provides pulse control across eight independent temperature zones, alternating between high and low fire settings. The system allows programmable excess air levels during different stages of the cycle, enhancing fuel efficiency, process precision, and temperature uniformity without relying on constant excess air. IMPS also includes a cooling mode, introducing air through burners and dedicated nozzles for reduced cycle times.

The kiln’s insulation includes NUTEC’s patented Jointless® ceramic fiber system rated to 2600°F (1425°C), ensuring thermal efficiency and durability. Double-labyrinth refractory and insulation brick seals combined with sand seals reduce heat loss and cold air infiltration.

This project builds on NUTEC Bickley’s longstanding relationship with the customer, which includes the delivery of 15 furnaces and ovens over the past decade to its transformer manufacturing division. The award further underscores NUTEC Bickley’s reputation for delivering advanced thermal processing systems to global leaders in high-tech manufacturing.

Wisconsin oven completes spray quench aluminum solution furnace for the defense industry

Wisconsin Oven, East Troy, Wis. announced the completion of a Horizontal Spray Quench Furnace for C/A Design located in Dover, NH. This furnace will be used for the solution treatment of aluminum. The system is designed to soak the product load at temperature in the furnace and then a pusher mechanism rapidly moves the load into the spray quench. The spray quench offers reduced distortion in comparison to submersion quenching.

The maximum temperature for this system is 1,150°F and it has sufficient capacity to heat a 200 pound aluminum load plus the work grid and product fixture. A temperature uniformity survey was documented for +/-10°F at 985°F to verify the furnace has the capability to meet AMS 2750G, Class 2 furnace and Instrumentation Type D requirements.

The spray quench is located in front of the oven and has vertical-lift, pneumatically operated doors on each end. The spray quench system utilizes fifty (50) fine mist nozzles located above, below, and on each side of the quench chamber to rapidly cool the product from all sides. Each nozzle is independently selectable from the touchscreen HMI and a variable frequency drive allows the pump speed to be adjusted to maintain a constant pressure to each spray nozzle.

One Minute Mentor: Continuous Operating Furnaces for Tool Steel Strips

The continuous heat treatment of tool steel is applied to low- or medium-alloyed carbon steel strips as well as martensitic stainless steels. The described lines produce high-quality strip with respect to uniform structure, flatness, and bright surface finish. Steel grades with 0.4 to 1.2% C, low and high alloyed, can be processed. 

Strip dimensions range between 10 to 750 mm (0.4 to 29.5 in.) wide and 0.05 to 4 mm (0.002 to 0.16 in.) thick. High quenching rates are necessary, especially for plain carbon steels. Cooling gradients of up to 600 K/s are possible in a molten lead-bismuth quench. Because two-stage quenching technology provides considerable advantages over quenching in oil, this method has been adopted worldwide. It is also possible to achieve isothermal transformation to bainite and pearlite using a molten metal quench, so this type of hardening and tempering line is extremely versatile.

One Minute Mentor: Vacuum Furnaces

The demands on vacuum-hardening technology have changed in recent decades. One of the most important considerations that must be met is the accomplishment of highest dimensional stability with optimal microstructural properties and minimal change of the surface of the workpieces. 

Minimizing exposure to air during the heat treatment by reducing the quantity of oxygen in a heat treatment furnace, as with creating a vacuum, is an excellent method for preventing changes in surface appearance and chemical composition.

Suppliers of modern vacuum furnaces are further faced with new demands, such as increasing quenching speed to improve microstructural and mechanical properties by reducing grain size, and enhancing hardness and toughness and/or reducing distortion due to the hardening process. Furthermore, quality standards such as AMS 2750d or North American Die Casting Association (NADCA), which describe temperature homogeneity or quenching speeds and resulting and needed workpiece properties, had a significant effect on furnace design and process control.
