3-D printed electronic membranes to prevent heart attacks


An Ultra-thin membrane, specially customised and 3-D printed to exactly match the patient's heart shape. Tiny sensors embedded in a grid of flexible electronics measure pulse, temperature, mechanical strain and pH level with far greater accuracy and detail than was possible using previous methods. Doctors can determine the heart's overall health in real-time and predict an impending heart attack before a patient has any physical signs – intervening when necessary to provide therapy. The device itself can deliver a pulse of electricity in cases of arrhythmia.

This electronic membrane can be installed in a relatively non-invasive procedure, by inserting a catheter into a vein beneath the ribs and then opening the mesh like an umbrella. At present, it is restricted to the exterior surface of the heart. However, new and more advanced versions are now being developed that will go directly inside the heart to treat a variety of disorders – including atrial fibrillation, which affects 2.5 million U.S. adults and 4.5 million people living in the EU, accounts for one-third of hospitalisations for cardiac rhythm disturbances and is a major risk factor for stroke.
Great progress is now being made in the monitoring, diagnosis and treatment of heart disorders, thanks to this and other breakthroughs emerging at this time, all of which are contributing to a rapid decline in mortality rates. By the 2040s, deaths from cardiovascular disease will reach negligible levels in some nations.
