htcfuze Remote Wound Management With Help of Smart PhonesWound patients typically get lots of care at home, either from visiting nurses or from home care providers. Now technology is coming to even this forgotten medical market. And not surprisingly, it is mobile phone technology with backing from a big gun: AT&T. What we know is that the Wound Technology Network, a telehealth-based wound management service, is giving out HTC smart phones equipped with iVisit software to many of its providers for sending images back to specialists for remote analysis:

Under a two year agreement with AT&T, Wound Technology Network will equip its clinical staff including physicians, nurse practitioners and physician assistants across South Florida and Southern California with HTC FUZE™ smart mobile devices when providing care in patient’s homes. Clinical staff will use the devices to access an application developed by iVisit which creates videoconferencing tools for mobile devices and PCs and speak live with a wound care specialist at Wound Technology Network’s tele-health center who will assist them to assess the patients’ wounds and perform the necessary treatment. To aid in the treatment process, clinical staff will also capture images of the patient’s wounds using the HTC FUZE™ and transmit the images to the wound care specialists to upload onto an electronic medical record which is immediately faxed to the patient’s primary care physician.

Flashback: Camera Phones to Interpret Visible World for Blind

There’s a new hope for treatment of patients with completely blocked coronaries. BridgePoint Medical out of Plymouth, MN has announced winning the European CE Mark of approval for its Chronic Total Occlusion (CTO) Crossing System that consists of the Stingray® and CrossBoss™ catheters. The package, which has yet to receive FDA clearance, is designed to cross chronic total coronary occlusions in arteries, and reinstate myocardial blood flow through these difficult vessels.
From the press release:

“We have seen many attempts to implement new tools for the treatment of chronic coronary occlusions over the years, but until now none of them have provided any advantage over the current treatment of using specialty guidewires,” said Gerald Werner M.D. Ph.D., Professor at the Klinikum Darmstadt in Darmstadt, Germany. “This system is the first to provide a new option for the frequent situation when our guidewires do not reach the vessel beyond the occlusion. The BridgePoint system makes it possible to find the true vessel lumen and conclude the treatment successfully…”
In a prospective clinical trial conducted in the European Union and a post-market registry conducted primarily in South America the BridgePoint System was 67%-85% successful in placing an interventional guidewire beyond a chronic total coronary occlusion. Complications with the system were similar to general PCI and stenting.

  • The Stingray™ CTO Re-Entry System has two components: The Stingray™ CTO Orienting Balloon Catheter and The Stingray™ CTO Re-Entry Guidewire
  • Familiar coronary balloon catheter and guidewire designs are enhanced with custom features for CTO crossing without changing routine practice
  • Flat shape of the Stingray™ CTO Orienting Balloon Catheter is intended to orient one exit port automatically toward the vessel true lumen upon low pressure inflation (4atm)
  • The Stingray™ CTO Re-Entry Guidewire’s distal probe is designed for exit port selection and re-entry into the vessel true lumen
  • crossboss BridgePoints Chronic Total Occlusions Crossing System Gets EU Green Light

  • Bi-directional rotation of the proximal torque device with the FAST SPIN Technique is designed to aid in advancement of the CrossBoss™ CTO Catheter
  • A 3.0F atraumatic rounded tip is designed for passage through the CTO
  • The device is intended to cross directly through the CTO or bypass the obstruction via a subintimal path
  • We bet that cardiac surgeons, who are already straining from an assault of Plavix and stents, don’t want to know about these little cath trinkets.

    jjrwer1234 A Review of The Latest in Plasma MedicineAn interdisciplinary team of European scientists has been studying the potential value of low-temperature atmospheric plasma for applications in medicine. One particular example is a device developed at Max-Planck Institute for Extraterrestrial Physics in Garching, Germany that can sterilize equipment by showering it with atoms stripped of their electrons. Unlike commonly known plasma, the low-temperature variety uses only a small number of stripped atoms to create the wanted effect.
    Here’s the abstract from New Journal of Physics of a recent review of plasma applications in medicine:

    This introductory review on plasma health care is intended to provide the interested reader with a summary of the current status of this emerging field, its scope, and its broad interdisciplinary approach, ranging from plasma physics, chemistry and technology, to microbiology, biochemistry, biophysics, medicine and hygiene. Apart from the basic plasma processes and the restrictions and requirements set by international health standards, the review focuses on plasma interaction with prokaryotic cells (bacteria), eukaryotic cells (mammalian cells), cell membranes, DNA etc. In so doing, some of the unfamiliar terminology—an unavoidable by-product of interdisciplinary research—is covered and explained. Plasma health care may provide a fast and efficient new path for effective hospital (and other public buildings) hygiene—helping to prevent and contain diseases that are continuously gaining ground as resistance of pathogens to antibiotics grows. The delivery of medically active ‘substances’ at the molecular or ionic level is another exciting topic of research through effects on cell walls (permeabilization), cell excitation (paracrine action) and the introduction of reactive species into cell cytoplasm. Electric fields, charging of surfaces, current flows etc can also affect tissue in a controlled way. The field is young and hopes are high. It is fitting to cover the beginnings in New Journal of Physics, since it is the physics (and non-equilibrium chemistry) of room temperature atmospheric pressure plasmas that have made this development of plasma health care possible.

    New%20Probe%20062009%20%28Custom%29 ProUroScan Uses Mechanical Sensoring to Visualize ProstateProUroCare Medical out of Eden Prairie, MN has filed an application with the FDA to receive approval for the firm’s prostate analysis tool. The ProUroScan device uses what’s known as “elasticity imaging technology” to measure the stiffness of the prostate by applying pressure to the organ and feeling the physical resistance through a sensor.
    CompactSystem%20%28Custom%29 ProUroScan Uses Mechanical Sensoring to Visualize ProstateHere’s more from the company about its technology:

    During a procedure similar in nature to the digital rectal examination for men, the clinician inserts the tip of the system’s probe into the patient’s rectum and palpates the prostate. Sensitive sensors on the head of the probe collect a sequence of pressure patterns when the probe is pressed against the prostate. The device consequently measures the prostate’s elasticity. Each scan produces an image of the prostate and compares elasticity measurements across the gland.
    u323nnnj ProUroScan Uses Mechanical Sensoring to Visualize ProstateUsing a sophisticated positioning system and complex mathematical algorithms, the ProUroScan technology is able to assemble the individual images it generates into a composite image, or “map” of the prostate. Tissue exhibiting comparatively less elastic properties is identified by darker colors on the map, similar to how areas of precipitation are displayed on a weather radar map.

    h234lkjj GlucoTrack Ear Lobe Non Invasive Glucometer
    Amy Tenderich of DiabetesMine recently met a representative of Integrity Applications, an Ashkelon, Israel firm that has developed the GlucoTrack non-invasive blood glucose monitor. The device, which we profiled about four years ago when it was still in prototype stage, uses ultrasound, conductivity and heat capacity in an ear clip sensor to take glucose readings in a matter of seconds. Integrity recently received European approval for the GlucoTrack and is now waiting for FDA’s blessings to market in the US.
    From DiabetesMine:
    tttytytyt GlucoTrack Ear Lobe Non Invasive Glucometer

    But even on the existing non-continuous model, the key question of course is how accurate is it? That’s the deal-breaker, because who’s going to switch to something less accurate than what we already have? The bottom line is that right now, Integrity’s data show that GlucoTrack is more accurate than other non-invasive technologies, but not as consistently accurate as current fingerstick meters.
    “We’re working to improve that. Our technology uses three different measurements simultaneously, and then correlates and averages the results for more precise readings,” Avner tells me.
    “Fine,” I reply, “But the big advantage of a device like this is doing away with the need for test strips. That only works if you’re accurate enough so people (who take insulin!) don’t need to do fingersticks alongside the ear measurements.”
    Naturally they’re feverishly gathering data. Even with improved numbers, they cannot predict whether the FDA would move GlucoTrack out of the “adjunctive therapy” category (a device to be used for extra information only).

    nn23432l Barco Unveils Two New Grayscale Diagnostic Screens
    At the RSNA Annual Meeting in Chicago this week, Barco will be showing off two new medical monitors that it has just announced. The Coronis Fusion 10MP is a 30 inch display that can also work as two independent side-by-side 5 megapixel panels. The Nio 5MP sports a 2096 x 2800 resolution and comes with Barco’s MediCal QAWeb online calibration system for consistent visualizations.

    With the Coronis Fusion 10MP, Barco continues the legacy of its leading Coronis products and introduces several new, unprecedented features that make the system particularly competent for grayscale diagnostic imaging. One of these innovations is a proprietary ‘SmoothGray’ technology which assures a more precise DICOM curve, thereby improving the visibility of subtle details. Furthermore, Coronis Fusion 10MP includes Barco’s proprietary Uniform Luminance Technology (ULT), which provides consistent brightness over the entire 30-inch screen surface.
    This new product will inherit the ergonomic, modern and widely acclaimed design from the successful Coronis Fusion 6MP DL. Just like the 6MP, the new 10MP will come as a complete, plug and play product bundle, featuring an ultra-fast display controller and the latest version of the MediCal QAWeb solution for worry-free Quality Assurance.

    jk2j3j4 Barco Unveils Two New Grayscale Diagnostic Screens

    One of the main advancements that have raised the diagnostic accuracy of the new Nio 5MP to the next level is the integration of a brand-new LCD panel based on IPS (In-plane switching) technology. Thanks to this new panel, grayscale images are presented with more brightness, improved contrast and better black uniformity, under any ambient light condition. Furthermore, the new panel sets itself apart with its extra high resolution of 2096 x 2800, while at the same time still supporting the 2048 x 2560 standard.
    Besides more brightness, contrast and resolution, the new Nio 5MP also scores high on luminance uniformity. Responsible for this is the integrated uniformity correction function, which spreads the luminance more evenly over the entire screen.
    The new Nio 5MP comes as a turnkey solution, including a high-speed display controller and an online system for calibration and Quality Assurance.

     iPhone CPR App Analyzes, Helps Improve Chest Compressions
    ZOLL Medical Corporation has released a new iPhone application designed to help in assisting people perform cardiopulmonary resuscitation. Of course because it has no FDA approval (see our recent post on the regulatory environment for mobile medical apps), it is being marketed as a training tool to learn the process of doing CPR. With the help of iPhone’s built-in accelerometer, it actually provides guidance regarding the quality of compressions.

    Using Real CPR Help®, the same proprietary technology found in all ZOLL defibrillators and AEDs, PocketCPR for iPhone provides CPR training with real-time feedback on the rate and depth of compressions. The app provides clear visual and audio step-by-step instructions and feedback to guide CPR practice and also reinforces the American Heart Association and International Liaison Committee on Resuscitation (AHA/ILCOR) recommendations on CPR.
    With practice on a manikin or resilient foam cushion, the iPhone’s internal accelerometer measures the movement of the user’s hands as simulated chest compressions are delivered. The visual and audio feedback helps to guide the user to the AHA/ILCOR recommended rate of 100 compressions per minute and depth of 1½ to 2 inches.
    Features:

  • Clear visual and audio step-by-step instructions on CPR performance, including initial steps for the Chain of Survival
  • Option to go straight to chest compressions for those who are familiar with the initial Chain of Survival steps
