Amsterdam-based Wright Medical Group NV agreed to acquire Alpharetta, Georgia-based Cartiva Inc., a private orthopedic company focused on thhe treatment of osteoarthritis of the big toe. Wright will acquire 100% of Cartiva's outstanding equity on a fully diluted basis for $435 million in cash.
Marlborough, Massachusetts-based Boston Scientific has agreed to acquire Fremont, California-based medical devices manufacturer Veniti in a deal valued at $160 million – an investor in Veniti since 2016, Boston Scientific has 25% stake in the company, paying $108 million for the remaining stake. Company officials agreed to pay up to $52 million after U.S. FDA approval of the Vici stent system. In June 2018, the company submitted a pre-market approval (PMA) application to the FDA; presently, the system is an investigational device in the U.S.
Carmel, Indiana-based Nanovis completed a $5.5 million funding round brokered by Commenda Securities. Key investors include Elevate Ventures, 1st Source Capital Corporation, Purdue’s Foundry Investment Fund, Commenda Capital, and Ellipsis Ventures.
Minneapolis, Minnesota-based Starkey Hearing Technologies' hearing aid with integrated sensors and artificial intelligence – Livio AI – tracks brain and body health, and has a natural user interface with tap control, language translation, and advanced environmental detection. The first device to track physical activity and cognitive health as measured by hearing aid use in social situations, the launch also includes a mobile app – Thrive Hearing; and three wireless accessories – the Starkey Hearing Technologies TV, the Remote, and the Remote Microphone +. With the Remote Micorophone+, Livio AI is also the first hearing aid featuring Amazon Alexa connectivity.
Toronto, Ontario, Canada-based Titan Medical, a medical device company focused on the design and development of a robotic surgical system for application in minimally invasive surgery (MIsS), has been granted U.S. Patent No. 10,058,396, "System and Apparatus for Insertion of an Instrument Into a Body Cavity for Performing a Surgical Procedure." The patent covers technology that advances the ease of use and positioning of robotic surgical systems, including single-port robotic surgical systems such as the company's SPORT Surgical System. The technology was developed internally at Titan and was led by Dr. Perry Genova, the company's senior vice-president of R&D.

Jeff Wills graduated from Stevens Institute of Technology in 2013 with a Bachelor’s in Mechanical Engineering. During this time he also worked at the Institute Machine Shop helping design, machine, and assemble projects for his fellow students. Following graduation, Wills gained industry experience at a small company designing and manufacturing industrial machinery for the plastics industry. From there he joined Schunk in 2016 and works in the Toolholding department focusing on custom engineered solutions using Schunk’s hydraulic expansion technology.
Brooklyn, New York - The worldwide market for 3D-printed parts is a $5 billion business with a global supply chain involving the internet, email, and the cloud – creating a number of opportunities for counterfeiting and intellectual property theft. Flawed parts printed from stolen design files could produce dire results: experts predict that by 2021, 75% of new commercial and military aircraft will fly with 3D-printed engine, airframe, and other components, and the use of AM in the production of medical implants will grow by 20% per year over the next decade.
A team at NYU Tandon School of Engineering has found a way to prove the provenance of a part by employing Quick Response (QR) codes in an innovative way for unique device identification. The researchers describe a method for converting QR codes, bar codes, and other passive tags into three-dimensional features hidden in such a way that they neither compromise the part's integrity nor announce themselves to counterfeiters who have the means to reverse engineer the part.
Materials researcher Nikhil Gupta, an associate professor of mechanical engineering at NYU Tandon; Fei Chen, a doctoral student under Gupta; and joint NYU Tandon and NYU Abu Dhabi researchers Nektarios Tsoutsos, Michail Maniatakos and Khaled Shahin, detail how they exploited the layer-by-layer AM printing process to turn QR codes into a game of 3D chess. Gupta's team developed a scheme that "explodes" a QR code within a computer-assisted design (CAD) file so that it presents several false faces – dummy QR tags – to a micro-CT scanner or other scanning device. Only a trusted printer or end user would know the correct head-on orientation for the scanner to capture the legitimate QR code image.
"By converting a relatively simple two-dimensional tag into a complex 3D feature comprising hundreds of tiny elements dispersed within the printed component, we are able to create many 'false faces,' which lets us hide the correct QR code from anyone who doesn't know where to look," Gupta said.
The team tested different configurations – from distributing a code across just three layers of the object, to fragmenting the code into up to 500 tiny elements – on thermoplastics, photopolymers, and metal alloys, with several printing technologies commonly employed in the industry.
Chen, the study's lead author, said that after embedding QR codes in such simple objects as cubes, bars, and spheres, the team stress-tested the parts, finding that the embedded features had negligible impact on structural integrity.
"To create typical QR code contrasts that are readable to a scanner you have to embed the equivalent of empty spaces," she explained. "But by dispersing these tiny flaws over many layers we were able to keep the part's strength well within acceptable limits."
Tsoutsos and Maniatakos explored threat vectors to determine which AM sectors are best served by this security technology, a step that Gupta said was crucial in the research.
"You need to be cost efficient and match the solution to the threat level," he explained. "Our innovation is particularly useful for sophisticated, high-risk sectors such as biomedical and aerospace, in which the quality of even the smallest part is critical."
