On this episode of The Pulse, a device that helps train the brain to turn sounds into images, detecting cancer by imaging the consumption of sugar, biomedical applications for a new hydrogel, and a nanofiber mesh that treats tumors with both thermotherapy and chemotherapy.
Half a millennium after Johannes Gutenberg printed the bible, researchers printed a 3D splint that saved the life of an infant born with severe tracheobronchomalacia, a birth defect that causes the airway to collapse. While similar surgeries have been preformed using tissue donations and windpipes created from stem cells, this is the first time 3D printing has been used to treat tracheobronchomalacia—at least in a human.
A new study suggests that CPAP therapy reduces nightmares in veterans with post-traumatic stress disorder and obstructive sleep apnea. Results show that the mean number of nightmares per week fell significantly with CPAP use, and reduced nightmare frequency after starting CPAP was best predicted by CPAP compliance.
The vOICe sensory substitution device is a revolutionary tool that helps blind people to use sounds to build an image in their minds of the things around them. A research team, led by Dr Michael Proulx, from the University's Department of Psychology, looked at how blindfolded sighted participants responded to an eye test using the device.
To unlock the potential of more frequent therapy, medical devices must move out of the doctor’s office and travel with patients to their homes and offices. But, this great opportunity is not without its challenges. The same patient who stands to reap great benefit from a home medical device may instead endanger themselves by applying the device incorrectly.
Long-term hearing loss from loud explosions, such as blasts from roadside bombs, may not be as irreversible as previously thought. Using a mouse model, the study found that loud blasts actually cause hair-cell and nerve-cell damage, rather than structural damage to the cochlea.
As Parker sees it, the three biggest obstacles to [design] success for patient care products, such as oxygen concentrators and ventilators, are portability, battery life, and reliability. To make home care products more portable, Parker has reduced the size of some valves up to 75%.
Is it possible, that in 2-3 years Brits, Germans, Scandinavians, and Russians will undergo cancer treatment, orthopaedic, or cardiac surgery procedures in Polish medical facilities more often? Treat teeth and get implants in dental clinics; take a cure in Polish sanatoriums?
Important new insights into how the brain compensates for temporary hearing loss during infancy, such as that commonly experienced by children with glue ear, are revealed in a research study in ferrets. The Wellcome Trust-funded study at the University of Oxford could point to new therapies for glue ear and has implications for the design of hearing aid devices.
The antibacterial effects of silver are well established. Now, researchers at Yonsei University in Seoul, Republic of Korea, have developed a technique to coat glass with a layer of silver ions that can prevent growth of pathogenic bacteria including Escherichia coli, Salmonella typhimurium and Campylobacter jejuni. The technology could be used to protect medical equipment.
With the 3rd Edition of IEC 60601-1 impacting U.S. design engineers in June, it is critical they are aware of the implications to their medical device designs. For home healthcare devices, there is a collateral standard that will have a specific effect. This article focuses in on powering these products and the items in the standard of significance for that aspect.
The firm received complaints of "cuff leak" or "cuff deflation" occurring when the inflation valve cap is inappropriately removed (pulled off, instead of snapped-off sideways). This requires the physician to re-inflate or replace the deflated tube to ensure the continued breathing support of the patient. Use of this recalled product can result in serious adverse health consequences, including death.
In the near future, a buzz in your belt or a pulse from your jacket may give you instructions on how to navigate your surroundings. Think of it as tactile Morse code: vibrations from a wearable, GPS-linked device that tell you to turn right or left, or stop, depending on the pattern of pulses you feel. Such a device could free drivers from having to look at maps, and could also serve as a tactile guide for the visually and hearing impaired.
Using the sensitive ears of a parasitic fly for inspiration, a group of researchers has created a new type of microphone that achieves better acoustical performance than what is currently available in hearing aids. The scientists will present their results at the 21st International Congress on Acoustics, held June 2-7 in Montreal.
One of the most interesting things about my position is seeing the changes in one of the most dynamic industries around—the medical device industry (and, in a broader sense, the healthcare industry). In my 13+ years of reporting on this industry, I’ve seen many changes and technological advances. It truly is remarkable to think about how far certain sectors of the industry have come in what is really a very short period of time.
Cochlear Americas Receives FDA Approval for the First and Only Ear Level Accessory for Waterproof Hearing with Cochlear ImplantsMay 31, 2013 1:07 pm | by PR Newswire | News | Comments
Cochlear Americas, the global leader in implantable hearing solutions, announced today that the US Food & Drug Administration (FDA) has approved a one-of-a-kind Aqua Accessory compatible with the Cochlear Nucleus 5 Sound Processor. The Aqua Accessory is a custom cover with a double zip lock seal designed to hold the processor and coil inside, and can be worn behind the ear in the normal position.
New research from the University of Southampton shows that copper and copper alloys will rapidly destroy norovirus - the highly-infectious sickness bug. The virus can be contracted from contaminated food or water, person-to-person contact, and contact with contaminated surfaces, meaning surfaces made from copper could effectively shut down one avenue of infection.
Men Who Want to Stay Active, Feel Younger, and Remain Socially and Professionally Engaged Should Address Hearing Loss, BHI AdvisesMay 23, 2013 4:18 pm | by PR Newswire | News | Comments
WASHINGTON, May 23, 2013 /PRNewswire/ -- Hearing health affects a man's lifestyle, and if he wants to stay active, feel younger, and remain socially and professionally engaged, he should address any hearing loss he may be experiencing. This is the overriding message that the...
Frequent heartburn was positively associated with cancers of the throat and vocal cord among nonsmokers and nondrinkers, and the use of antacids, but not prescription medications, had a protective effect, according to data published in Cancer Epidemiology, Biomarkers & Prevention, a journal of the American Association for Cancer Research.
New research from the University of Southampton has shown that blind and visually impaired people have the potential to use echolocation, similar to that used by bats and dolphins, to determine the location of an object. The study, which is published in the journal Hearing Research, examined how hearing, and particularly the hearing of echoes, could help blind people with spatial awareness and navigation.
A new study looking at sleep-disordered breathing and markers for Alzheimer's disease risk in cerebrospinal fluid and neuroimaging adds to the growing body of research linking the two. But this latest study also poses an interesting question: Could AD in its "preclinical stages" also lead to SDB and explain the increased prevalence of SDB in the elderly?

Scientists at Princeton University used off-the-shelf printing tools to create a functional ear that can "hear" radio frequencies far beyond the range of normal human capability. The researchers' primary purpose was to explore an efficient and versatile means to merge electronics with tissue.
WASHINGTON, May 1, 2013 /PRNewswire/ -- In recognition of Better Hearing and Speech Month, the Better Hearing Institute (BHI) is encouraging people with questions about their hearing to take advantage of the warm days of spring and go out and "window shop" by visiting a...
The manufacture of hearing aids has traditionally involved a time-consuming, manual process that limited the amount of production that could be achieved by a single technician. However, with the implementation of rapid prototyping technology alongside CAD/CAM solutions, this process has been sped up exponentially. This article looks at the changing trend for the production of hearing aids.
