  • Using Nitinol and Lasers to Make Articulated Endoscopic Tool Tips

    In minimally invasive and natural-orifice transluminal endoscopic surgery, doctors require articulation in surgical tool tips to improve dexterity and gain access to hard-to-reach areas. Because surgical tool tips generally afford only straight-line access, articulation adds an extra degree of freedom. While as much as 90° of articulation is desirable, assembling conventional hinged joints at this scale is challenging. To overcome the difficulty of creating endoscopic tool tips affording the...

    The British press has lately been all a-buzz with the story of Craig Gerrand, MD, consultant orthopedic surgeon at Newcastle-upon-Tyne Hospitals NHS Trust  (Newcastle-upon-Tyne, Northumberland, UK) who used a 3-D printer to replace a large section of a man's pelvis.Craig Gerrand shows off a pelvis model.The unnamed patient, in his 60s, was suffering from chondrosarcoma, a rare form of cancer. Gerrand told Ben Farmer, reporting for The Telegraph (Chatham, Kent, UK), “Since this cancer does...
  • Stretching the Old Biomaterial Paradigms

    Do new biomaterials require new paradigms, or does their introduction to the market create paradigms? It is almost hard to believe that some of the most prominent resorbable biomaterials today have been in use in medical devices since the 1960’s. Although the sum total of human knowledge on material properties and their interactions with human tissues has increased greatly since those days, the final devices used in patients have taken little if any advantage of this new data.Why is that?Most...
  • How Mobile Health Is Changing MedTech—Or Not

    Some say mobile health could make half of existing medical devices obsolete. Some say even more.And while there is plenty of debate on this subject, many say a change is gonna come to the medtech industry.“Perhaps the bottom line is the device market of the future will be markedly different than the past,” says Brian Baum, founder and CEO of Baltimore–based health data startup vitaTrackr Inc.People might call it by different names: mobile health, telehealth, connected health, or iHealth. But...
  • Could Digital Health Make Most Medical Devices Obsolete?

    Don't say you weren't warned about the coming mobile health tidal wave.A recent keynote address at MD&M West suggested that digital health technology could end up displacing half of traditional medical devices. That figure might even be an underestimate, says regulatory expert George Samaras of Samaras & Associates Inc. (Pueblo, CO). In an email, which we have posted below, Samaras stressed the importance of first distinguishing between sales numbers or the number of types of medical...
  • Are You RoHS Ready?

    For the medical device industry, complying with the Restriction of Hazardous Substances (RoHS) directive is anything but simple. The directive, which requires medical device makers to stop using lead and five other hazardous substances from products sold in Europe by July 2014, has lead to growing concerns about tin whiskers in solders. For years, the primary solder used in the device industry was tin-lead—the latter metal helps slow the growth of tin whiskers, small hair-like crystalline...
