University of Minnesota researchers have developed a blood vessel replacement made of biological materials in a lab. The lab-grown vessels have no living cells at implantation and could be used as a graft for kidney dialysis patients. The lab-engineered blood vessel replacement is the first nonsynthetic, decellularized graft that is repopulated with cells using the […]
University of Minnesota researchers are taking 3D printed organ models to the next level: They look and feel like the real thing, and integrated sensors help surgeons train. There’s even the potential that such artificial models may someday become the real deal – “bionic organs” used to replace damaged biological organs. The Minnesota researchers published […]
Recent months have seen a host of important cardiology research breakthroughs related to new cardio devices and diagnostics, tissue engineering and the overall understanding of heart disease and its treatment. For example, a customizable robotic heart sleeve – developed at Harvard University and Boston Children’s Hospital – has demonstrated advantages over other heart assist devices […]
People who have lost feeling in their limbs or have lost the ability to move them may soon have those sensations restored thanks to a slew of recent brain-controlled device innovations. While we are moving toward less invasive methods like electrode-filled caps on the head, there are still more invasive implants that are benefiting those […]
University of Minnesota researchers 3D printed tiny stretchable electronic sensory devices that could enable bionic skin for surgical robots – or a new class of wearables directly printed onto human skin. Their work appeared May 5 in the journal Advanced Materials. “This stretchable electronic fabric we developed has many practical uses,” said Michael McAlpine, a […]
A University of Minnesota–led research team has successfully warmed large-scale animal heart valves and blood vessels that were previously preserved at low temperatures. The discovery of this rewarming process is pivotal for organs and tissues that are left in storage for transplantation for extended periods. “This is the first time that anyone has been able […]
Researchers at the University of Minnesota aim to research epilepsy using non-invasive brain scans taken immediately following, rather than during, a seizure.
"This is the first-ever study where new non-invasive methods were used to study patients after a seizure instead of during a seizure," says University of Minnesota biomedical engineering professor and senior author Bin He. "It’s really a paradigm shift for research in epilepsy."
MASSDEVICE ON CALL — A catheter-based procedure to close holes in patients’ hearts proved no better at preventing recurrent strokes than medication alone, according to a study published today in the New England Journal of Medicine.
Researchers compared use of NMT Medical’s StarFlex septal closure system with drug therapy against drug therapy alone, concluding that there were no statistically significant differences in stroke prevention between the 2 options for patients with patent foremen ovale, a hole between the upper chambers of the heart.
