Wearable VR system guides coronary artery surgery

Maksymilian Opolski of the Cardinal Wyszynski Institute of Cardiology used a VR system combining a custom app and Google Glass to clear a blocked coronary artery. The patient had chronic total occlusion, which  is difficult to clear with catheter-based percutaneous coronary intervention.   Surgeons often cannot visualize the blockage with CTA imaging. The system provided 3D reconstructions of the artery during the procedure, […]

Ingestible sensor continuously monitors heart, breathing rates

MIT researchers are developing ingestible sensors that measure heart  and breathing rates from within the gastrointestinal tract using sound waves. This type of sensor could make it easier to assess trauma patients, monitor soldiers in battle, perform long-term evaluation of patients with chronic illnesses, or improve training for professional and amateur athletes, the researchers say. […]

Phone tracks health with out wearable sensors

Javier Hernandez Rivera of Rosalind Picard‘s Affective Computing Group at MIT is developing a health monitoring phone that does not require a wearable.  BioPhone derives biological signals from a phone’s accelerometer, which the team says captures small body movements that result from one’s heart beating and chest rising and falling. Hernandez said that BioPhone is meant […]

Chip uses ECG to monitor heart, improving wearable accuracy

Samsung’s  Bio Processor uses ECG  to continuously measure the electric activity of the heart, improving its accuracy.  It must be worn on the skin near the heart, and includes built-in flash memory and Bluetooth for connecting to one’s phone.  The chip can also monitor PPG, ECG, skin temperature, GSR and body fat. The company describes this as a breakthrough […]

Toward a 3D printed heart

Carnegie Mellon‘s Adam Feinberg is developing 3D printing techniques that could in the future be used to repair the heart.  This work is aimed at alternative solutions for the 4,000 Americans currently waiting to receive a heart transplant. Feinberg described his progress:  “We’ve been able to take MRI images of coronary arteries and 3-D images […]

Optogenetics used to regulate heartbeat

Oxford’s Gil Bub and and Stony Brooks’ Emilia Entcheva have used optogenetics, a method used to control neurons, to regulate heartbeat. Arrhythmia patients currently use pacemakers or drugs to control heart rhythm.   These approaches can stop or start waves, but cannot provide fine control over wave speed and direction. In the Bub and Entcheva study, […]

Device detects heart attacks with one drop of blood

UCLA’s Chi On Chui has developed a device that brings lab quality bio-molecular assessments to point-of-care settings, such as clinics, ambulances or homes. SELFA (Semiconductor Electronic Label-Free Assay) could reduce emergency room time for heart attack patients by hours. Similar to a diabetic glucose sensor, SELFA uses a single drop of blood, taken wherever symptoms occur, […]

Faster, personalized, 3D printed heart models for surgery planning

MIT and Boston Children’s Hospital researchers are converting heart MRI scans into 3D printed physical models,  for surgical planning,  in 3-4 hours.  Previously, the process took 10 hours. The project, which limits human input to increase accuracy, is led by Professor Polina Golland.  Physicist Medhi Moghari enhanced the precision of the MRI, decreasing the dependence on generic models, […]
