  • 3-D Imaging Method Unmasks Secrets of the Beating Heart

    Oh, my beating heart! One day, its image may be captured in 3-D by a high-speed microscope designed by German researchers. Scientists at the Max Planck Institute of Molecular Cell Biology and Genetics in Dresden combined Selective Plane Illumination Microscopy (SPIM) and inventive image processing to reconstruct multi-view movies of the beating heart of a zebrafish.Each movie covered an individual plane of the heart. They then used the correlations between the individual planes to generate...

  • How a Packaging Design Firm Is Reinventing Catheter and Guidewire Dispensing

    The word innovation is often associated with complex new devices that will disrupt current practice. But strategic tweaks or additions to existing products can sometimes have just as significant an impact.The DISK system—which stands for dispenser integrated system kit—is one such example. The bronze winner in the Medical Product Packaging, Graphic Instructions, and Labeling Systems category of the 2014 Medical Design Excellence Awards combines two products—a clipless dispenser for catheters...

  • How Heat-Seeking Missile Technology Can Detect Malaria

    It turns out that technology used in heat-seeking missiles can be leveraged to quickly detect blood borne pathogens such as malaria parasites. Australian researchers took a focal plane array (FPA), used in missiles to detect tanks, and connected it to an infrared imaging microscope and a synchrotron light source. Within a matter of minutes, the FPA can detect the presence of malaria in a single red blood cell.The FPA detectors used in the research were initially developed in the 1990s for use...
  • How Nanotubes Could Improve Cancer Diagnostics

    University of Houston researchers are using nanoscience to extract molecules from live cells without killing or damaging the cells. Their method could lead to new possibilities for diagnosing cancer and other diseases.The scientists used magnetized carbon nanotubes to retrieve molecular information safely from the cells. Nanoengineering allowed them to keep the cells alive and to assess changes in the cells over time, Zhifeng Ren, a physics professor and principal investigator at the university...
  • How to Turn Surgical Robots into Shapeshifters

    A group of U.S. and German researchers think they’ve come upon a materials innovation that could enable deformable surgical robots—and perhaps other types of exotic medical devices.Anette Hosoi, a professor of mechanical engineering and applied mathematics at MIT, and her former graduate student Nadia Cheng, worked alongside researchers at the Max Planck Institute for Dynamics and Self-Organization and Stony Brook University to experiment with phase-changing material built from wax and foam,...
  • How Google and Novartis Might Revolutionize Contact Lenses

    Google’s founders may have recently downplayed the high tech giant’s healthcare plans. But a new partnership with Novartis, announced Tuesday, shows that Google is pretty serious when it comes to one medical device technology: contact lenses.When the news came out in January that Google planned to develop a contact lens that could help diabetics keep track of their blood glucose levels, company officials said they were looking for partners with expertise in bringing such products to market.That...
  • Developing Polyisoprene Materials that Meet USP <381> Guidelines

    By Saman Nanayakkara, Shu Peng, and Gino G. BancoA new grade of polyisoprene compounds complies with USP <381> guidelines for both Type I and Type II elastomeric closures.Natural rubber has been utilized in a variety of general industrial and commercial applications since the mid-1800s. In select applications, it has also found favor in the medical industry. Derived from the latex of the Pará tree, it is composed of long chains of isoprene monomers. However, the recognition that certain...
  • FDA Announces Recall of Manual Resuscitator

    FDA has announced a Class I recall of a manual resuscitator manufactured by Ventlab LLC (Grand Rapids, MI). The reason for the recall, according to FDA, is that the duckbill valve inside the device may stick, preventing air from passing through the valve to the patient. If a patient does not receive oxygen or if treatment is delayed, an inadequate supply of oxygen to the tissues (hypoxia) and too shallow or too slow breathing (hypoventilation) may occur, causing a life-threatening situation....
  • What Medtech Can Learn from Web Software and Neuroscience

  • Magnesium Alloys Perform Disappearing Act in the Knee

    Materials research and development is part of the bread and butter of medical device innovation. Whether you’re making a stent, a wound-care bandage, or an injection septum, the device is only as good as the material it’s made from.For example, researchers at North Caroline A&T are hard at work developing metal alloys for orthopedic implant applications. One target material is magnesium, a metal element that is also an essential body nutrient. However, the researchers face a range of...
  • Why Mexico Is Still Challenging for Medtech Designers

    By Miguel Angel Torres Tello and Carlos Alfonso Rodríguez SierraMexico is recognized as one of the top Latin American markets for medical devices. But globally, there are still plenty of challenges when it comes to meaningful research and development—and medical device design. To start, Mexico is still far behind countries like United States or China.
