Hugo Campos. Photo credit: Laura A. Oda, San Jose Mercury News Guitar in hand, Hugo Campos launches into a variation of the classic protest song “It Isn't Nice” by Malvina Reynolds. Not a professional singer, his voice is nonetheless calm, not self-effacing, “That's not right / I've told you twice / It isn't nice, it isn't nice...” But Hugo is talking about the...
There are many applications, particularly in the medical space, where ferroelectric RAM, or FRAM, is the memory technology of choice. Unlike EEPROM of flash memory, FRAM doesn’t need a high internal voltage for writing operations, thereby increasing both the writing speed and the endurance of the memory. Also key to medical applications is the fact that the FRAM is resistant to...
  Fans of Android (and people interested in the possible medical applications for the operating system) will want to take note of this interesting post in Wired.com’s GadgetLab blog detailing Google’s attempts to assure the public that the famously open OS will, indeed, remain open.   The new version of Android (which is deliciously known as Honeycomb) still has not been...
It wasn't long ago that we encouraged readers to keep track of FDA's new innovation pathway. We hold to that. But since FDA has been busy creating other paths to market—namely the new Class I Medical Device Data Systems category—it makes sense for folks to keep a close eye on that as well. From FDA's news release:   Medical Device Data Systems are off-the-shelf or...
Three-dimensional technology continues its penetration in the medical device technology market. Hologic has just earned FDA approval of its Selenia Dimensions System, the first 3-D mammography imaging system ever approved by the agency.   "Physicians can now access this unique and innovative 3-D technology that could significantly enhance existing diagnosis and treatment approaches,...
Yesterday I imagined a world in which celebrities endorse medical devices using Tom Brady's torn ACL as an example. But it's not just professional athletes that have these injuries. In fact, children and teens who participate in activities such as football, basketball, soccer, and gymnastics can suffer from torn ACLs as well. This type of injury carries a more severe sting for...
How close is FDA to regulating wireless networks as medical devices? Well, that depends on who answers the question.   FDA received reports of six patients dying and 44 more being injured as a result of IT-related problems last year. These numbers are in addition to 260 reports of malfunctions that had the potential to cause harm. CDRH director Jeffrey Shuren says that these...
A manufacturer of data acquisition systems has expanded its family of LAN-controlled transient recorders to include several high-speed modules that offer sampling speeds of 240 MS/sec or 120 MS/sec at 14-bit or 16-bit vertical resolution. Suitable for medical device testing, the TPCX-24014 and TPCX-12014 series combine the company’s measurement precision, which features vertical and offset...
Another tidbit from the town hall meeting in Irvine, CA: Anette Asher of the LSIT Global Institute said that she is on a team working on a guidance document for IT systems.   "Data sits on some sort of IT system, and our goal is to make sure that data can be trusted by anyone who has to review it, collect it, use it, share it, exchange it, etc. We address things such as security...
A scanning electron microscope image of a complete sensor chip. A polymer-coated microbridge can detect vapor concentrations on chip arrays. The technology could lead to a low-power electronic nose used to sniff out health problems such as asthma, lung cancer, and kidney diseases. Imec (Leuven, Belgium) and Holst Centre (Eindhoven, The Netherlands) have developed the integrated sensing...

  Originally Published MEM Spring 2005   The advent of electronic health records (EHRs) is a major topic of discussion among insurance and physician groups. Much of the focus is on using EHRs to streamline patient records and eliminate redundant data. Some groups just want to get the correct diagnosis code to the insurance carrier or HMO more quickly. At the Health Information...
