A patient at Hammersmith Hospitals NHS Trust has become the first in the UK to receive an artificial heart pump inserted without the need for surgery. Doctors at Hammersmith Hospital successfully placed the world’s smallest heart support system, a 4mm-wide device, into the patient’s heart, by inserting it into an artery in the groin and passing it up into the heart. The pump, implanted on Thursday (November 28) and removed a day later, assisted the patient’s heart in the crucial few hours after coronary artery bypass surgery. The device offers hope for patients previously considered too ill to be operated on, by providing temporary support for the heart muscle during the critical period after a heart attack or surgery.
“This new impeller pump technology which can be put into the heart without invasive surgery will revolutionise the way we deal with heart disease,” comments Mr Peter Smith, consultant cardiac surgeon at Hammersmith Hospitals NHS Trust and lead surgeon. “The ease of using these pumps, particularly in patients with very diseased or damaged hearts, means that we can now successfully treat patients that we otherwise would have been unable to.“
The “Impella Recover® LP 2.5 left ventricle percutaneous placement” pump, manufactured by the German company Impella Cardiosystems, sits in the left ventricle, the largest chamber of the heart. Dr Kevin Beatt, one of the cardiologists assisting the procedure, explains “The pump sits inside the heart, and despite its tiny size can pump up to 2.5 litres of blood every minute. Because it is so small, it can be put in place without the need for any surgery. A tiny hole is made in the artery in the groin, and using guide wires, the pump is advanced through the artery until it sits in the right place.” X-rays are used to check the pump is in the right place. The pump uses an electrical motor connected to a 3mm wire which extends out of the patient, where it is connected to a battery and control pack the size of a small laptop computer.

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.
Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...
Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.
"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...
The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.
Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.
Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
