SERDANG, 14 November – Rapid advances in modern materials-processing technologies are reshaping the future of medical device manufacturing, particularly in the production of cardiovascular stents used to treat heart disease.
Experts say these breakthroughs are set to significantly enhance safety, durability and treatment outcomes for millions of patients worldwide.
For decades, the manufacturing sector relied on traditional machining methods such as turning, milling and drilling to produce high-precision components. However, as medical devices evolve towards more complex geometries, the limitations of conventional techniques have become increasingly apparent.
Today, cutting-edge approaches including laser machining, abrasive jet machining and laser-based additive manufacturing—especially Selective Laser Melting (SLM), which is emerging as catalyst for a new era in medical device innovation.
Universiti Putra Malaysia (UPM) Deputy Vice-Chancellor (Industry and Community Relations), Prof. Dr. Ir. Hang Tuah Baharudin, said SLM technology is playing a pivotal role in shaping the next generation of cardiovascular stents, as it enables the creation of finer, more flexible lattice structures that are fully compatible with human blood vessels.
He added that the cobalt-chromium-molybdenum (CoCrMo) alloy used in the process offers superior strength, corrosion resistance and enhanced biocompatibility.
“With the combination of SLM and CoCrMo, stents can be designed to match a patient’s specific anatomy. This not only reduces the risk of restenosis, but also supports better tissue healing,” he said.
The medical industry is also experiencing accelerated progress in three key areas: personalised and patient-specific device design, development of biocompatible materials and bio-fabrication, and integration of automation and robotics in manufacturing.
The use of medical imaging data, such as CT and MRI scans, now enables devices to be customised to individual patient needs. At the same time, bioprinting technologies are opening new frontiers for the development of artificial implants, tissues and organs. Automation and robotics are further enhancing precision, reducing errors and speeding up production cycles.
Prof Hang Tuah noted that the convergence of these modern technologies is expanding opportunities for innovation while elevating the overall quality of care.
“Rapid advancements in materials-processing technologies have the potential to completely transform the landscape of medical device manufacturing, delivering significant benefits to patients and to the global healthcare system,” he said.
