Royal Philips (NYSE:PHG) announced today that one-year results of its Define PCI study that reported improved outcomes and less recurrent angina. The Define PCI study assessed the level of residual ischemia found in patients following a percutaneous coronary intervention (PCI) using a blinded instant wave-free ratio (iFR) pullback measurement, … [Read more...] about Philips touts post-stent imaging study results
Research & Development
Company researchers developed cardiac ablation technology that mimics the navigation system of electric fish. Scientists have studied electric fish for decades to determine how and why they discharge electricity. Recently, a couple of biomedical engineers at Boston Scientific realized that the way these fish use their electrical impulses … [Read more...] about How fish physiology is enabling Boston Scientific to help atrial fibrillation patients
Pulsatile durability testing is a time-consuming part of the vascular stent approval process. Accelerated test designs can deliver a high throughput when every specimen counts. Pete Bailey, Instron There are many quality controls applied to the design and release of coronary and other vascular stent devices, but a proof test of pulsatile … [Read more...] about Passing the test with vascular stents
Catheter-related medtech remains an exciting and innovative field — if our sister site Medical Design & Outsourcing's latest list of startups to know is any indication. For example, Neurescue (Copenhagen) touts its aortic occlusion catheter as the first of its type with computer-aided, intelligent safety feedback — and pressure-limited … [Read more...] about These startups are advancing catheter-related medtech
MIT and Brigham and Women’s Hospital researchers say they have a way of splitting ventilators which could address many of the safety concerns — potentially boosting the supply of ventilators amid the COVID-19 pandemic. They have demonstrated their concept’s effectiveness in the lab — but they still caution it should be used only as a last resort … [Read more...] about MIT researchers may have invented a safer way of splitting ventilators
Researchers at the University of Bordeaux in France have engineered human tissue to be woven into blood vessels and treat diseased or damaged blood vessels. Synthetic blood vessel grafts are typically made of woven synthetic polymer yarn and used to replace diseased arteries. However, the body's immune system sometimes recognizes the material as … [Read more...] about How to weave human tissue into new blood vessels
Amid the global crisis caused by the coronavirus pandemic, hospitals and healthcare facilities are reporting shortages of vital equipment that not only keeps the patients safe, but the staffers, too. One important device for which demand has ramped up is ventilators for patients who need assistance with their breathing due to the respiratory … [Read more...] about Could these DIY ventilators stop coronavirus from killing people?
At the Mayo Clinic Glass Shop, scientific glassblowing creates glass tubing and apparatuses for cardiac, transplantation and tissue perfusion research — and more recently, to help fight the COVID-19 pandemic. Steve Anderson is one of only two scientific glassblowers in Minnesota. As a senior scientific glassblower at Mayo Clinic, he has … [Read more...] about How glass tubing supports Mayo Clinic innovation
Medical tubing allows clinicians to administer fluid and or even devices — as well as potentially allow for gas flow. And that's just the beginning. Common applications of medical tubing include ventilators and IVs, but tubing also finds uses supporting access devices and as a delivery method for other devices. For example, tubing can be used to … [Read more...] about What is medical tubing used for?
A new way to replace a patient's damaged blood vessels may be on its way, as researchers in France are figuring out a way to "knit" new vessels with a collagen-based extracellular matrix. Inserm researcher Nicolas L'Heureux and his colleagues at Inserm/Université de Bordeaux's tissue bioengineering unit published a study in Acta Biomaterialia to … [Read more...] about Is it possible to ‘knit’ replacement blood vessels?
