Mechanical heart valves are so loud that they cause insomnia

A quarter of patients with mechanical heart valves claim that the valves disturb their sleep, according to a new study. “For some patients, the closing sound of their mechanical heart valve reduces their quality of life, disturbs their sleep, causes them to avoid social situations and leads to depression and anxiety,” said Kjersti Oterhals, a

Artificial intelligence accurately predicts stroke risk

Machine-learning algorithms, a form of artificial intelligence, accurately predicted people’s risk of heart disease and stroke, according to new research from the University of Nottingham. Researchers and computer scientists compared the risk guidelines for heart disease and stroke from the American College of Cardiology with 4 machine-learning algorithms to analyze the risk of a patient

What is catheter (PTCA) treatment?

Asahi Intecc Catheter treatment (percutaneous transluminal coronary angioplasty, or PTCA, treatment) is one of the methods of treatment for diseases such as angina pectoris and myocardial infarctions that are caused by the heart’s blood vessels (coronary arteries) becoming clogged or narrowed by cholesterol. Previously it was common to treat such diseases with medication or, if

Deaths prompt Abbott recall of Thoratec HeartMate II controllers

Brad Perriello, Executive Editor Abbott (NYSE:ABT) is recalling nearly 29,000 controllers for the HeartMate II implantable heart pump made by its Thoratec subsidiary after 26 patients died trying to change out the controllers on their own. The March 29 recall of 28,882 controllers for the HeartMate II left ventricular assist device follows 70 reports of

This could be the battery-free solution for pacemakers

A new energy storage system charges itself using ions from inside the human body – providing an exciting alternative to traditional batteries used in pacemakers, according to researchers at the University of California at Los Angeles and the University of Connecticut. Researchers at the universities developed a bio-friendly energy storage system called a biological supercapacitor;

3D printing is stransforming maxillofacial surgeries: Here’s how

Customized, 3D models for pre-surgical preparations are transforming maxillofacial surgical procedures in the U.K. – thanks to Stratasys’ PolyJet 3D printing. Queen Elizabeth Hospital in Birmingham, U.K. is using Stratasys’ Objet Eden350V 3D Printer and has reported having an up to 93% reduction in surgical planning time that comes with standard anatomical models. They have

Apple Watch detects atrial fibrillation using built-in technology

The Apple Watch can automatically detect atrial fibrillation (AF) using its built-in heart rate sensor and artificial intelligence, according to a new study. The research used a deep neural network that was based on photoplethysmographic (PPG) sensors that are frequently found in smart watches. When paired with an artificial intelligence-based algorithm, Apple Watch’s heart rate

TransEnterix CEO: Robotic surgery has a big problem

Todd Pope has been working in the surgical robotics space for over a decade. As the CEO of TransEnterix, which has developed Senhance surgical assistance device, Pope believes the surgical robotics market is about to explode. But before it can take off, Pope noted that players have to address a really big problem with robotic

Titan Medical CEO wants to up the game in robotic surgery: Here’s how

Titan Medical – the young, upstart Canadian robotic surgery company – is making a comeback this year. Just today, the company announced the completion of initial formative human factors studies for its Sport single port robotic surgical system. The Sport system boasts the ability for a variety of surgical instruments on snake-like arms to be deployed

‘No-touch’ heart bypass surgery reduces strokes

A recent study from the University of Sydney and Sydney Heart and Lung Surgeons has shown that a new “no-touch” beating heart bypass surgery technique has reduced post-operative stroke by 78%. The procedure, known as an OPCABG, also reduced post-operative mortality by 50% compared to traditional coronary artery bypass grafting. It reduced renal failure by

Navtar expands medical tubing portfolio

Natvar, a Tekni-Plex company, has launched thermoplastic microextrusion tubing. The technology is used in neurovascular interventional therapies and surgical applications. Microextrusion tubing offers a replacement for glass and fluoropolymers, and the company promises short development lead time. The new tubing option could help drive innovation in these therapeutic spaces. Microextruded options include monolayer, coextruded, multi-lumen tubing or profiles

North American artificial disc replacement market to reach $614.5 million

The North American artificial disc replacement (ADR) market – which covers Canada, Mexico and the U.S. – is set to more than double from $274.6 million in 2016 to around $614.5 million by 2023, representing a compound annual growth rate of 12.2%, according to research and consulting firm GlobalData. The company’s latest report states that key

Engineered tissue could eliminate radiation for bone marrow transplants

University of California San Diego engineers have created artificial bone tissue that could eliminate the need for radiation before bone marrow transplants. Shyni Varghese, a bioengineering professor at UC San Diego Jacobs School of Engineering, led a team to develop a bone-like implant to eliminate the pre-treatment radiation that kills stem cells in a patient’s bone

Micron Solutions boosts revenues, narrows losses in Q1

Precision medical device components maker Micron Solutions reported improvements with its finances during the first three months of 2017–even as it faced challenges related to validation requirements. “We have made several improvements in quality systems, capacity and our ability to meet customer requirements.
