components Medical technology More efficiency in the manufacture of cardiovascular products Since its foundation in 1970, Aerotech has developed into a reliedupon partner of the medical industry. Their medical business unit has long been one of the strongest in terms of innovation and turnover of motion con trol and positioning systems. The steadily growing portfolio includes laser welding and stent cutting solutions as well as purpose-built motion systems and components that can increase throughput while maintaining maximum precision. Over the years, Aerotech has become one of the main suppliers of motion control systems for the manufacture of implantable interventional cardiovascular devices. “Aerotech’s commitment to quality and performance has always been a perfect fit for the needs and requirements of the medical industry. So it was natural for us to focus more on this industry,” says William Land, business development manager for Aerotech, Inc. and responsible for the medical device market segment. Even more than other industries, medical technology requires a deeper technical understanding of the applications and manufacturing requirements. “Working closely with partners and customers on an ongoing basis has given us the industry insight we need to provide valuable, future-proof automation solutions to medical OEMs for nearly 50 years,” he says. First and foremost, it is a matter of understanding the needs and developments of the market. Another important task is to keep up to date and closely observe which medical technology developments the industry is focusing on. “We must always be pushing our capability developments to realise the desired medical technologies of the future,” William Land continues. William Land, business development manager at Aerotech, Inc.: “Working closely with partners and customers on an ongoing basis gives us exactly the industry insights we need to provide valuable and future-proof automation solutions to medical OEMs for nearly 50 years” Integration and automation partner Aerotech was involved in the development of some of the first lathes for cutting intraocular lenses and has been supplying specialist products to the interventional cardiovascular industry since the early 1970s. As a result, Aerotech has world-renowned tube laser machining systems that are relied upon by the largest medical OEMs and device manufacturers in the world. “We are able to manufacture fully integrated machines for custom applications,” asserts William Land, business development manager at Aerotech, Inc. 42 no. 1, March 2022

components Precise laser processing at maximum speed In the field of interventional cardiovascular device manufacturing, Aerotech is one of the main suppliers of motion control systems and has been for many years. “We manufacture custom-built linear and compact rotary servo systems that are critical to the manufacture of stents and many other trans-catheter devices and their delivery systems,” explains William Land. “Our mature technology enables precise laser processing of catheters and stents at speeds that make them economical for the market.” Fewer machines for the same number of stents For example, the fully-integrated VascuLathe motion system combines automated material handling functions with direct-drive linear and rotary motion. “Because of the throughput a truly integrated design offers, medical device manufacturers need fewer machines to produce the same number of stents compared to conventional production methods,” William Land says of the benefits. However, due to its flexibility, the VascuLathe can also be used, for example, to meet an increased and varying production demand on the existing production area. Precise microlaser processing is particularly in demand in medical technology; the AGV3D laser scanner is optimally designed for this, but is also used in additive processes Innovations for the entire industry “As experienced developers and automation partners, we can keep pace with the very short innovation cycles in the industry,” emphasises Simon Smith, European director at Aerotech. “This future-oriented, constructive cooperation at eye level is very much appreciated by our customers.” The stent manufacturing solution is also merely a continuation of the successful high-performance motion systems and components for medical technology and life science applications. Other examples from the medical technology solution range include stent, guidewire, and catheter cutting, pacemaker and catheter laser welding systems, intraocular lens (IOL) and contact lens manufacturing, DNA and blood sequencing, X-ray machines, MRI scanners and CAT scanners. VascuLathe: innovative cutting system for precise stent production at high throughput Automated material handling As a complete motion and material handling subsystem, Vascu - Lathe includes an automated, pneumatically-activated ER collet assembly and an optional combined bushing/tube feed mechanism. This enables the sequential, fully automated produc - tion of various products from tube material of any length. Also a wet cutting configuration is available for applications that require cooling fluid during the cutting process. Advanced control architecture As a platform, the VascuLathe is available with a powerful, yet simple and intuitive Aerotech controller. Users can optimise current, speed and position servo loops for maximum performance without much programming. Additional functions such as multi-block lookahead minimise geometry errors even at the smallest radii by “anticipating” tracking errors. With the “position synchronized output” (PSO) function, laser pulses can be controlled synchronously in order to maintain optimal laser power coupling at variable cutting speeds. Customer-focused integration One of Aerotech’s focuses is to provide exactly as much integration as the customer needs. “Many medical OEMs have in-house automation and machine-build groups or preferred integration partners,” specifies William Land. “Aerotech is considered the first point of contact and subject matter experts for precision motion control subsystem integration for these teams.” In other cases, medical OEMs were looking for a partner to help them manufacture the entire manufacturing cell for a specific process. “We are able to produce fully integrated machines and manufacturing systems for individual application areas,” assures William Land. “In every case, we ensure that the systems we have in operation at our customers’ facilities, whether individual components or complete machines, operate at full capacity and deliver high-quality results.” And Simon Smith emphasises in conclusion: “Manufacturers of cardiovascular products gain a competitive advantage in the highly competitive market of medical device manufacturing with our high-precision motion systems and components.
