High-precision microriveting joins complex medical devices

Admedes Schuessler, Germany, has developed a superflat micro-riveting process technology for clinical applications that may require complex combinations of engineering materials. It is designed for tantalum and gold markers, and provides superior process features, such as high precision with minimum crevice formation, and super-flat 3D contouring. The process is scalable and flexible, and can be used with all types of radiodense materials.

Bose Electroforce electrodynamic test system features nanometer resolution

Bose ElectroForce, Eden Prairie, Minn., introduces two high-accuracy test systems: the ElectroForce 3200 Series III and the ElectroForce 3330 Series II test instruments. They achieve the highest measured displacement resolution and accuracy for electrodynamic test systems. With measurement resolution of a nanometer and accuracies in the range of microns, these systems extend the range of testing, providing an order of magnitude improvement in displacement measurement at low amplitudes.

Burpee specializes in stents and stent-like devices of Nitinol and other materials

Burpee Materials Technology, Eatontown, N.J., specializes in high-yield, high-quality manufacturing of stents and stent-like devices and components. Expertise ranges from fine neurovascular and coronary devices to large AAA/TAA and valve components fabricated from Nitinol, cobalt-chrome, stainless steel, and other biocompatible metals.

Flexinol shape memory alloy actuator springs withstand millions of cycles

Dynalloy, Tustin, Calif., offers state-of-the-art shape-memory Flexinol alloy actuator technology. Flexinol actuator springs are designed for applications with low force and high travel requirements. These springs can contract and relax multiples of their length. When Flexinol actuator springs are used within the correct range, repeatable motion from the springs for millions of cycles is reasonable.

Fort Wayne Nitinol wires exceed ASTM chemistry requirements

Fort Wayne Metals, Ind., manufactures wire products from several grades of Nitinol commonly used in medical applications, as well as Nitinol alloys for other applications. Each medical grade is comprised of near-equal atomic weight percentage of nickel and titanium. Our most common medical grade, NiTi#1, exceeds chemistry requirements set forth by ASTM F2063 for surgical implants. All grades are available in either the cold worked (CW) condition ready for heat treatment, or as straightened super-elastic (SE) wire.
