Lasers & photonics 76 Light show


The use of lasers across medicine is well-known – but they’re just as important in the manufacturing space too. Yet not all lasers are created equal. Andrea Valentino talks to experts across the sector to understand more about the advantages of so-called femtosecond devices, why they’re particularly helpful in crafting a new generation of intricate medical technology, and whether they’re necessarily appropriate for every factory floor.

Filtration & fluid control 83 Tubes transformed


Used to ventilate the middle ear and drain fluid or enable the delivery of antibiotics, tympanostomy tubes have remained largely unchanged in their design for 50 years or more, though they are known to have shortcomings. That is now changing thanks to a new study by Harvard’s Wyss Institute, the John A. Paulson School of Engineering and Applied Science, and the Massachusetts Eye and Ear (MEE) teaching hospital. Jim Banks speaks to MEE investigator Dr Aaron Remenschneider about a new approach to designing fluid-transporting implantable medical conduits.

Materials 92 Polymers rise


As one of the largest categories within the advanced material industry, polymers continue to grow within the medical devices market. Thanks to their versatility, they can be used to construct medical scaffolds, drug delivery carriers, implants, and bone cement, the success of which is due to their biocompatibility. Scientists continuously research polymers to uncover their potential for medical devices and biomimetic applications. Allison DeMajistre speaks to Eric Appel, associate professor of materials science and engineering at Stanford, and Joseph Kennedy, professor of polymer science and chemistry at The University of Akron, to discover the latest polymer developments for medical devices.

104 Mixing metals


Choosing the right material is crucial in the medial device industry, as infection or failure is a major issue for healthcare. Patrick McGuire speaks to Amit Bandyopadhyay, Boeing distinguished professor at WSU’s School of Mechanical and Materials Engineering, and Indranath Mitra, postdoctoral research fellow of physiology and biomedical engineering at the Mayo Clinic, about the importance of material selection to better control infection.

107 Improved integration Poor osseointegration and implant failures are still common occurrences in healthcare due to the lack of contact between the implant and bone. To improve this, implant surfaces are of particular interest for researchers in developing implant materials. Monica Karpinski speaks to Guillermo Ameer, professor of Biomedical Engineering and Surgery at Northwestern University, and Jessica Bertrand, professor and head
