Arterys Cardio DL Application for Cardiac MRI Ventricle Segmentation FDA Cleared

Thu, 19 Jan 2017 18:17:10 +0000

Arterys, a San Francisco firm, won FDA clearance, following recent European CE Mark approval, to introduce its Arterys Cardio DL software that automates the process of segmenting ventricles on cardiac MRI imaging scans. Arterys claims that in a clinical setting the application is able to perform segmentation as accurately as experienced docs doing it manually, […]

Electrospun Nanofibers as Orthopedic Scaffolds Help Bones Heal, New Implants Settle In

Thu, 19 Jan 2017 18:03:19 +0000

Chemists at the University of Helsinki have created a method of using nanofibers and thin-film biomaterials as orthopedic scaffolds to help regenerate bones and to help implants settle into their new home. The nanofibers are made of electrospun hydroxyapatite, a naturally occuring mineral form of calcium apatite. The team developed a new, needleless twisted wire, method […]

ATTYS Open-Source Biosignal Acquisition Device Helps Developers Build Wearable Gadgets

Wed, 18 Jan 2017 23:17:44 +0000

Glasgow Neuro Ltd, a young Scottish firm, has released an open-source data acquisition device for wearable health monitoring applications. It can amplify electrocardiography (ECG), electromyography (EMG), and electroencephalography (EEG) signals for processing by external devices such as tablets and smartphones. The ATTYS is able to transmit raw, uncompressed signal data at 24 bits wirelessly via Bluetooth. Apps […]

Proclaim DRG Dorsal Root Ganglion Neurostimulator for Chronic Pain Released in Europe

Wed, 18 Jan 2017 20:10:39 +0000

St. Jude Medical, now a part of Abbott, is making available in Europe its Proclaim DRG Neurostimulation System. The implant features 4-ports and 16-channels to help control chronic neuropathic pain by electrically stimulating the dorsal root ganglion (DRG), a body of neurons responsible for managing pain signals moving up the spine. Of note, St. Jude so far […]

Fast Method for Printing Biocompatible Implantable Microscopic Medical Devices

Wed, 18 Jan 2017 17:51:25 +0000

Tiny implantable medical devices with moving parts and drug chambers are a part of the future of medicine. Researchers at Columbia University have made a big step towards that by developing a new method for creating millimeter scale mechanisms out of hydrogels. Hydrogels are biocompatible, but they’re difficult to work with. The Columbia team developed […]

New Technique Improves Electric Vagus Nerve Stimulation to Treat Chronic Inflammation

Wed, 18 Jan 2017 17:06:47 +0000

Electric stimulation of the vagus nerve stimulation is a powerful emerging technique for managing a number of conditions, including chronic inflammatory diseases. Yet, while targeting biophysical mechanisms involved in inflammation, one can stimulate others that manifest in unpredictable side effects. Researchers at Georgia Tech have invented a way of delivering electrical stimulation in a more […]

Penile Implant for Erectile Dysfunction Erects Itself When Heated

Tue, 17 Jan 2017 19:47:42 +0000

Researchers at University of Wisconsin-Madison recently reported on a new penile implant designed to help men with erectile dysfunction. The device relies on nitinol, a memory alloy composed of nickel and titanium that was developed at the now defunct Naval Ordnance Laboratory. The metal responds to temperature changes by changing its shape, and the implant takes a […]

Temporary Graphene Tattoo Measures Vitals

Tue, 17 Jan 2017 18:04:18 +0000

IEEE Spectrum is reporting that researchers, Deji Akinwande and Nanshu Lu at the University of Texas at Austin, have developed a bio-integrated health sensor that can be applied to the skin like a temporary “tattoo” to take measurements of vitals signs. Utilizing graphene, the tattoo has a significantly smaller form factor than conventional sensor equipment.  […]

Adaptive PCR, a New Powerful Technique to Speed Up Genetic Analysis

Tue, 17 Jan 2017 15:57:30 +0000

Researchers at Vanderbilt University have developed a new way of performing PCR (polymerase chain reaction), or amplifying DNA so there’s enough of it to perform genetic analysis. The technique is called adaptive PCR and it relies on using only left-handed DNA (L-DNA), which is the mirror of normal DNA, to help regulate and monitor PCR. […]
