Growing human hearts: The answer is spinach leaves?

We could soon be using spinach to grow human hearts, thanks to new research from the Worcester Polytechnic Institute, the University of Wisconsin-Madison and Arkansas State University. One of the problems that researchers have faced is how to create a vascular system that can deliver blood deep into developing tissues. There hasn’t been much success

The top medtech stories of early 2017

The new Trump administration and Republican Congress – and all the accompanying change and uncertainty –is the major story for the medical device industry. But there are many other medtech stories worth noting from the first quarter of 2017. There was an FDA warning over Abbott’s Absorb bioresorbable stent, a continued spate of M&A deals, a

MR Solutions offers MRI imaging solution for cardiologists

MR Solutions has created 9.4 tesla cryogen-free, preclinical scanners that are ideal for use among cardiologists. The new helium-free Flexiscan and Powerscan scanners are powerful and have multi-modality by integrating PET and SPECT capabilities. The Flexiscan doesn’t need a specialist to operate and can be used by running pre-defined settings. The SPECT image system works by

Disposable lead wires market to reach nearly $1 billion

Use of disposable lead wires is growing globally, and sales are expected to reach $999.4 million by 2025. As reported by Grand View Research, a key factor driving growth is the rising incidence of hospital-acquired infections. North American hospitals are by far the largest sector of disposable lead wire adopters. Care centers with remote monitoring

9 cardiology breakthroughs you need to know

Cardiology breakthroughs couldn’t come soon enough because heart disease is the No. 1 killer of men and women in the U.S. About 610,000 Americans die of heart disease per year, and an additional 735,000 Americans suffer from a heart attack. The statistics terrify. High blood pressure, high cholesterol and smoking are some of the top

Nanoengineers 3D-print biomimetic blood vessel networks

University of California San Diego researchers have 3D-printed a functional blood vessel network that they believe could someday be used in artificial organs and regenerative medicines. The team’s work was published in Biomaterials. Previous work in the field has yielded simple and costly structures, the researchers said, that are not capable of integrating with the body’s own

Aortic stenosis test for open heart surgery is inaccurate

An approved exercise test that determines whether people with aortic stenosis need open heart surgery has only 60% accuracy, according to a new study by the University of Leicester. Cycling on a stationary bike typically determines whether a person needs surgery. If the patient becomes breathless while cycling, it is typically recommended to have valve

Medtronic: Certain stent grafts may confuse during implantation

Some Endurant and Endurant II bifurcated stent graft systems could fool doctors into thinking a more serious endoleak is taking place during the implant procedure, causing the doctors to take unnecessary extra interventions, Medtronic is warning in a letter to health providers published in Europe. The voluntary recall announcement, posted today on the website of

Blood test could accurately diagnose heart disease

A simple blood test could accurately diagnose heart disease in 2 hours, according to new data published by life science company Prevencio. Prevencio researchers and the Massachusetts General Hospital collaborated to develop a clinical and multi-protein blood test that could diagnose obstructions in coronary arteries, leading to the prevention of a heart attack. The blood test, known

Gore’s Viabahn VBX: The very model of a modern major product launch

The Viabahn VBX built by Gore is the first and only balloon expandable stent graft with an iliac indication. It is a balloon-mounted, ePTFE-coated, stainless-steel stent. To deploy a physician accesses the artery and blows up the balloon, forcing the device to expand. The balloon provides radial strength while the stent it deployed, but also

This 3D heart tissue beats—and is made from multiple cardiac cell types

Scientists at Toronto’s York University have created 3D heart tissue that has a synchronized beat. They think the tissue could improve understanding of cardiac health as researchers develop new treatments. Muhammad Yousaf, a York University chemistry professor, and his graduate student team stuck three types of cardiac cells together to get a 3D heart tissue

Turns out unneeded ICD shocks have costs

A Stanford University School of Medicine–led team of researchers has discovered that implantable cardioverter defibrillators that administer shocks unnecessarily could actually do more harm than good. Those who have had a ventricular arrhythmia, heart attack, survived sudden cardiac arrest and have a congenital heart disease typically have an ICD implanted, according to the American Heart

Bard announces ePTFE encapsulation services for OEM customers

C.R. Bard announced today it is making its expanded polytetrafluoroethylene (ePTFE) encapsulation services available to OEM customers. Bard originally developed the ePTFE encapsulation services its own branded stents. Bard OEM customers will now have access to the material and processes needed for encapsulating their own component or device. Such ePTFE encapsulation is especially suited for

Growing heart muscle cells: 2 breakthroughs you need to know

Host animal hearts and 3-D printed scaffolds—both appear to be showing promise when it comes to growing heart tissue to restore damaged hearts. Researchers at Johns Hopkins University recently reported that they’ve had success using host animal hearts to grow mature and viable heart muscle cells from stem cells. Meanwhile, a 1-micron-resolution scaffold made with a 3-D printer

BioSig taps Minnetronix to develop new cardio display system

BioSig Technologies has contracted with Minnetronix to develop the first version of its Pure EP system, according to a letter to shareholders disclosed Friday. BioSig, based just outside Minneapolis, is developing a cardiac signal acquisition and display system which is designed to assist electrophysiologists in making clinical decisions for patients with abnormal heart rates and rhythms, including
