MediValve, a company based in Kibbutz HaMa’apil, Israel, just received 510(k) clearance from the FDA to bring to the U.S. its acWire guidewire. The device is primarily designed to position transcatheter prosthetic heart valves with greater precision than many current delivery systems allow.
The advantage of the acWire is that once its active components are moved past the diseased valve, it’s opened up like a flower and drawn back to the valve, aligning itself snugly just past the valve opening. Three radiopaque markers on the petals help the physician visualize how the device is positioned before placing the valve.
ResMed has released its new AirFit P10 nasal pillows mask for positive airway pressure therapy, that weighs only 1.6 ounces (45 grams) and features the company’s new venting technology, called QuietAir, that reduces exhaust noise by 50% compared to its predecessor model. So not only will the patients benefit, but their bed mates will also be thankful for a bit more peace at night. Additionally, the headgear was designed for a quick and secure fit to get to bed quickly and to be sure the mask stays on throughout the night.
ResMed even claims that in its own internal research, people using the P10 mask received an average of 40 minutes of extra sleep per night compared to the company’s older, comparable model.
Huge networks like Google and Facebook inspire many scientists to model interactions between people. Posts can go ‘viral’ and grow to pandemic proportions in a few hours; today’s infectious diseases spread faster through social media than in real life. These networks can also help with real diseases and to that end Google monitors the internet for flu-like symptoms and publishes its data in Google Flu Trends, the results of which several scientists confirmed the correlation with reality in scientific journals. Lada Adamic from Facebook Data Science, took it a bit further and studied the evolution of memes and how they adapt to different communities. Memes can be ideas, political statements, and thoughts, and people post them on their timeline to inspire their connections. Friends copy the meme but sometimes change it slightly so it better fits their own audience. In that way Facebook posts develop and change over time, the best memes survive and get copied, some mutations are less fruitful and slowly fade away. It seems almost an analog to Darwin’s survival of the fittest and Dawkins’ selfish gene theory. For the research, Adamic used the following statement that was posted by 470,000 Facebook users in exactly the same way:
“No one should die because they cannot afford health care, and no one should go broke because they get sick. If you agree, post this as your status for the rest of the day”.

Zensorium, a Singapore-based startup was showing off at CES in Las Vegas its iPhone pulse oximeter called Tinké, that provides continuous blood oxygen level monitoring. Along with measuring oxygen levels, Tinké also tracks the heart rate, respiratory rate, and heart rate variability. The device, which weighs .4 oz (10.7g), works with a companion iOS app that displays the different cardiac metrics measured. The app displays a Vita index that is a fitness score computed from the user’s heart rate, blood oxygen level and respiratory rate. The app also displays a Zen score based on the heart rate variability data, and is a supposed measure of the user’s state of relaxation.
In order to use the Tinké , it is first connected to the dock connector of the iPhone. The user needs to wait untill a red light appears on the device, after which the user is required to place his or her thumb over the two holes on top of the unit and the reading is taken. The iOS app automatically registers and tracks daily readings and helps users track their cardiac metrics over an extended time.
(MedPage Today) — Programs aimed at boosting mental performance in older people showed some benefits after 10 years in objective tests and participants’ self-ratings, but not in performing real-world tasks, researchers found.
iHealth Launches New Wristworn Pulse Oximeter, Ambulatory Heart and Blood Pressure Monitors at CES 2014
iHealth (Mountain View,CA), a subsidiary of China-based Andon Health, launched a new wristworn pulse oximeter, an ambulatory heart monitor, and an ambulatory blood pressure monitor at CES 2014. The pulse oximeter continuously measures blood oxygen saturation (SpO2) and pulse rate at the finger tip, and is connected to a wrist strap that has an LED display showing the readings. The device also syncs via Bluetooth to the iHealth iOS app to display and track blood oxygen levels over time. Like other pulse oximeters, the device works by projecting two light beams, one red and the other infrared, onto the blood vessels in the finger. Oxygenated blood absorbs more infrared light and allows more red light to pass through, whereas deoxygenated blood absorbs more red light and allows more infrared light to pass through. A photodetector opposite the light emitters measures the ratio of red to infrared light received and from that calculates the amount of oxygen in the blood.
The second device unveiled by iHealth is an ambulatory heart rhythm monitor that is attached to the user’s chest using an adhesive patch. The monitor syncs with an iOS device using Bluetooth connectivity and displays a complete ECG on the user’s phone.
