We’ve all seen or heard commercials from the American Stroke Association (ASA) encouraging people who suspect they might be having a stroke to call 9-1-1 right away, because “time lost is brain lost.”. Stroke is the No. 5 cause of death in the United States, killing nearly 130,000 people a year. That’s one in every 20 deaths, according to the ASA. But even if you survive a stroke, you are not even close to being out of the woods.
Before he was an “Outdoor Man” marketing sporting goods in the Rocky Mountains as the Last Man Standing, Tim (“The Tool Man”) Taylor did most of his work indoors — on a little show called Home Improvement. Fortunately for the often accident-prone know-it-all, he had a competent sidekick in the mild-mannered Al Borland, who often knew a better way to get things done properly.
When incorporating human factors into medical device development, conducting user testing and gathering feedback from the device’s target end users is critical. To do this properly, the end user groups must be appropriately defined.
The process for launching a product with an injection-molded component has continuously developed over decades. Prototype tooling plays an important role in this process.
Many new health care technologies have advanced over the past decade to enable doctors to perform more procedures in their offices over hospital only settings. However, hysteroscopy — used to identify or treat problems of the uterus — has been slower to respond to this shift.
Combining the sense of smell with rapidly evolving virtual reality (VR) technology — enabling medical applications including helping soldiers with post-traumatic stress disorder (PTSD)— is the mission of OVR Technology, a startup in Burlington, Vt.
When designing parts for injection molding, you may need to consider finishing options, which can help improve a part’s mechanical properties, enhance surface finishes, facilitate the final assembly process, or just further customize your part or parts.
Developing medical device parts is a high-stakes process, and material choice is an important decision. Five strong contenders include PEEK, PEI, and PPSU; polycarbonates; medical-grade liquid silicone rubber; and 3D-printed titanium and ABS-like WaterShed XC 11122.
Medical device design and development is the cyclical process of creating a device for a specific task or set of tasks, and then continuously reevaluating its effectiveness and improving upon it until the device reaches obsolescence. Design and development begins with ideation and the creation of a concept that, if found to be both fiscally and clinically viable, is then designed, engineered, and prototyped. This preclinical period includes bench testing — accomplished through simulated use of the product — and animal testing, along with any necessary redesign work.
Throughout the process, the proposed medical device, and the process by which it will be manufactured, is examined for flaws that may negatively impact the device’s safety, market viability, regulatory acceptance, customer satisfaction, usability, or profitability. Any shortcomings are corrected, and the improvements applied to the final design. Due to the wireless connectivity capabilities of many modern medical devices, cybersecurity and interoperability also must be incorporated into the design. Clinical testing is conducted, using human subjects, to further expose flaws and confirm product strengths. Once both the product design and the manufacturing process have been validated and approved by the U.S. Food and Drug Administration (FDA), production and commercialization of a device may begin.
Each year, nearly 800,000 people in the U.S. experience a stroke, and almost 90 percent of those are ischemic strokes in which a clot cuts off blood flow to part of the brain. To prevent further injury, blood flow to the brain must be restored as quickly as possible.
Empatica Inc has received clearance from the FDA for Embrace, its award-winning smart watch. Embrace uses AI (advanced machine learning) to monitor for the most dangerous kinds of seizures, known as "grand mal" or "generalized tonic-clonic" seizures, and send an alert to summon caregivers' help.
For the first time, researchers have fabricated sensing elements known as fiber Bragg gratings inside optical fibers designed to dissolve completely inside the body.
A team of scientists from the National University of Singapore (NUS) has developed a way to wirelessly deliver light into deep regions of the body to activate light-sensitive drugs for photodynamic therapy (PDT).
Extremely fine porous structures with tiny holes - resembling a kind of sponge at nano level - can be generated in semiconductors.
Tyndall and Sanmina Corporation have announced a research collaboration, which will focus on the development of a novel wireless technology for a commercial wrist-worn health-monitoring platform.
When studying diseases or testing potential drug therapies, researchers usually turn to cultured cells on Petri dishes or experiments with lab animals, but recently, researchers have been developing a different approach: small, organ-on-a-chip devices that mimic the functions of human organs, serving as potentially cheaper and more effective tools.
Cells communicate with each other through a number of different mechanisms. Some of these mechanisms are well-known: in animals, for example, predatory threats can drive the release of norepinephrine, a hormone that travels through the bloodstream and triggers heart and muscle cells to initiate a "fight-or-flight" response.
Each year 40,000 babies in the U.S. are born with a congenital heart defect, often caused by a defective heart valve, which is estimated to account for 8,000 to 13,000 new cases in the U.S. alone.
A team of researchers at DGIST has recently developed a technology which enables to acquire a high resolution mass spectrometry imaging in micrometer size of live biological samples without chemical pretreatment in the general atmospheric pressure environment.
