Regenerating heart valves
The human heart beats approximately 35 million times every year, pumping blood into the circulation via four different heart valves. In more than four million people each year, heart valves fail for different reasons, including birth defects, age-related deteriorations and infections. At present, clinicians use either artificial prostheses or fixed animal and cadaver-sourced tissue to...
Ultra-Strong Flexible Biomaterials
Hydrogels are already being developed for use as scaffolds for tissue engineering, vehicles for drug delivery, actuators for optics and fluidics, and models for biological studies of tissue-supporting material called the extracellular matrix. But these water-rich polymer gels are weak; they rupture if stretched just a little, and they break easily compared with resilient biological...
Soft exosuits offer a new way to assist the elderly in maintaining or restoring their gait, in rehabilitating children and adults with movement disorders due to Stroke, Multiple Sclerosis and Parkinson’s Disease, or to ease the physical burden of soldiers, firefighters, paramedics, farmers and others whose jobs require them to carry extremely heavy loads.For decades...
Improving Balance and Gait Control
Balance in humans relies on complex feedback from the senses that govern the body’s mechanical stability. Wyss Institute and Boston University researchers have discovered that random vibrations, too gentle to be felt, can improve the sensory feedback system and may restore stability through a mechanism known as “stochastic resonance”. By incorporating vibrating elements in insoles...
Preventing Infant Apnea
Clinicians and engineers at the Wyss Institute and the University of Massachusetts Medical School have developed a unique and proprietary system that reduces the onset of neonatal apnea in low birth-weight infants in a clinical trial at Beth Israel Deaconess Medical Center. The system makes use of the concept of Stochastic Resonance to reset the...
Mechanically-Activated Drug Targeting Nanotechnology
The Wyss team has developed a novel drug targeting nanotechnology that is activated locally by mechanical forces, either endogenous high shear stresses in blood created by vascular occlusion or mechanical energy applied locally using low-energy ultrasound radiation. Today, vascular blockage is the leading cause of death and disability in United States and Europe. Current therapies...
