Cath lab procedure could replace major heart surgery in some patients
The Hospital of the University of Pennsylvania (HUP) is participating in a nationwide clinical trial of a new valve repair device that could replace major heart surgery in some patients. A tiny clip – delivered by a catheter and deployed in the heart to repair a malfunctioning and leaking mitral valve – is building a favorable safety and feasibility profile as the EVEREST Phase I clinical trial nears completion.
Severe mitral valve regurgitation (MR) is a debilitating condition that causes shortness of breath, fatigue and palpitations. In the United States, about 250,000 people develop significant MR each year, with almost 50,000 requiring surgery. The clip is designed to secure the valves leaflets near the center of the valve so that blood leakage is minimized and the heart pumps more efficiently. This new device could decrease a patients hospital stay, result in fewer complications, provide a quicker recovery time, and significantly reduce health care costs. "In my most recently treated patient, we utilized two clips to reduce his MR from severe to mild. It has been six months since his procedure, and he has no symptoms whatsoever," says Howard C. Herrmann, MD, Director of Interventional Cardiology & the Cardiac Catheterization Laboratory at Penn, and principal investigator for HUPs component of the EVEREST Trial.

The more electronics steer, accelerate and brake cars, the more important it is to protect them against cyber-attacks. That is why 15 partners from industry and academia will work together over the next three years on new approaches to IT security in self-driving cars. The joint project goes by the name Security For Connected, Autonomous Cars (SecForCARs) and has funding of €7.2 million from the German Federal Ministry of Education and Research. Infineon is leading the project.

A research team led by physicists at the Technical University of Munich (TUM) has developed molecular nanoswitches that can be toggled between two structurally different states using an applied voltage. They can serve as the basis for a pioneering class of devices that could replace silicon-based components with organic molecules.
The development of new electronic technologies drives the incessant reduction of functional component sizes. In the context of an international collaborative...
At the LASYS 2018, from June 5th to 7th, the Laser Zentrum Hannover e.V. (LZH) will be showcasing processes for the laser material processing of tomorrow in hall 4 at stand 4E75. With blown bomb shells the LZH will present first results of a research project on civil security.
At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...
There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?
At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...
