Why Adjusted Risk Likelihood Should Displace The Risk Priority Number
While the RPN primarily represents a risk event’s severity, perhaps a more important attribute to focus on is the risk event’s likelihood of occurrence. In this provocative article, Mark Witcher, Ph.D., proposes an adjusted risk likelihood rating approach that emphasizes a risk event’s likelihood of occurrence.
The transition to the U.K.’s new regulatory regime has officially begun as of Jan. 1, 2021. All medical devices on the U.K. market must be registered with the MHRA. Discover the 10 actions you should take to prepare for the U.K. Conformity Assessment process.
The first article in this two-part series covered details associated with economic operator responsibilities, overall QMS considerations, and common challenges during implementation of the EU’s Medical Device Regulation (MDR) and the EU’s In Vitro Device Regulation (IVDR). This article focuses on typical challenges experienced during the technical documentation assessments conducted by the notified bodies.
Application of artificial intelligence (AI) and machine learning (ML) in medical devices is making possible AI/ML-driven diagnostics and personalized treatments. By digesting the different jurisdictional AI/ML regulatory frameworks that have been released (draft or enforceable), along with personal experience with the agencies, John Giantsidis, president of CyberActa, Inc., identifies the common denominators crucial to success.
The transition to the EU’s Medical Device Regulation (MDR) and In Vitro Diagnostic Regulation (IVDR) is not an easy undertaking. This first article in a two-part series highlights the sections that need close attention regarding economic operator responsibilities, overall QMS considerations, and common challenges during implementation. Ensure a smooth transition and avoid pitfalls!
WHITE PAPERS & CASE STUDIES
Manufacturing Process: Tools For A Successful Startup
Medbio offers a number of tips to follow for a successful startup in designing and producing injection-molded parts.
Injection molding has numerous key parameters that must tie together in order to make a repeatable molding process. Medbio offers a solution that utilizes cavity pressure curves, key process parameter tolerances, and automation to automatically reject parts that do not make the cut in in the molding process.
Designing a product with consideration for the manufacturing process can reduce production times and costs, as well as simplify development of transport, storage, and protection solutions.
A global medical device company came to Donatelle for help perfecting a silicon seal component to meet the new ISO 27186:2010 standard. In this case, a seal with micro-features is needed to reliably isolate the four-pole electrical contacts between the pacemaker and defibrillator and fit inside the 6.3 mm medical device.
Devices such as introducer sheaths, delivery catheters, endoscopes, and neurovascular microcatheters aim to minimize trauma during insertion and removal, reduce tissue inflammation, enable maneuverability through tortuous blood vessels, and improve patient comfort. Surface properties should promote smooth movement between certain device components.
Noninvasive Optical Sensors Provide Real-Time Brain Monitoring After Stroke2/21/2018
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.
Embrace Becomes First FDA-Cleared Seizure-Monitoring Smart Watch2/5/2018
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.
Researchers Create Fiber Optic Sensors That Dissolve In The Body2/5/2018
For the first time, researchers have fabricated sensing elements known as fiber Bragg gratings inside optical fibers designed to dissolve completely inside the body.
NUS Researchers Develop Wireless Light Switch For Targeted Cancer Therapy1/30/2018
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).
TU Wien Develops New Semiconductor Processing Technology1/22/2018
Extremely fine porous structures with tiny holes - resembling a kind of sponge at nano level - can be generated in semiconductors.
Tyndall, Sanmina Partner To Develop Sub-GHz Wearable Health Monitoring Platform1/10/2018
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.
An Organ-On-A-Chip Device That Models Heart Disease1/2/2018
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.
Nanowire Device Holds Promise To Detect Cancer With A Urine Test12/26/2017
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.
Developing The First Pediatric Heart Valve Designed To “Grow” With The Child12/20/2017
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.
Mass Spectrometric Imaging Technique Makes Diagnosis Easier And Smarter12/17/2017
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.
