Light-reflecting balloon catheter for non-invasive heart repair
Certain Congenital Heart Defects (CHD) called Atrial Septal Defect (ASD) and Ventricular Septal Defect (VSD) occur when openings in the septum that divides the upper and lower heart chambers causes oxygen-rich blood from the upper chamber to mix with oxygen–poor blood from lower chamber. According to the Centers for Disease Control and Prevention, ASD alone... -
Tough Gel Adhesives
A Band-Aid® adhesive bandage is an effective treatment for stopping external bleeding from skin wounds, but an equally viable option for internal bleeding does not yet exist. Surgical glues are often used inside the body instead of traditional wound closure techniques like stitches, staples, and clips because they reduce the patient’s time in the hospital... -
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... -
Pop-Up MEMS
Recent decades have seen rapid development in the manufacture of microelectromechanical systems (MEMS) at the micrometer scale, mostly based on silicon wafer processing techniques, with characteristic length scales of millimeters to nanometers. However, standard MEMS techniques are often inappropriate for producing machines with complex 3D topologies and varied constituent materials at the mesoscale, at sizes...

Video/AnimationMORPH: A new soft material microfabrication processWhat has the ability to move and show its colors, is made only of silicone rubber and manufactured at the millimeter scale? A soft robotic peacock spider. Researchers have combined three different manufacturing techniques to create a novel origami-inspired soft material microfabrication process that goes beyond what existing approaches can achieve at this small scale.... -
Video/AnimationTough Gel AdhesivesInspired by the mucus secreted by the Dusky Arion slug, researchers at the Wyss Institute have developed a surgical adhesive that can adhere to wet and dynamic surfaces inside the body, including the heart, lung, tendons, cartilage, and bone. Coupled with a novel tough hydrogel, which can undergo huge amounts of deformation without breaking, this...

Video/AnimationThe milliDelta RobotDelta Robots are comprised of three articulating arms connected to an output stage. They are extremely precise and agile, and can be used for “pick & place” and 3D Printing. Researchers at the Wyss Institute and Harvard SEAS have developed a millimeter-scale delta robot, the “milliDelta.” Possible applications at this scale include microassembly, micromanipulation, and... -
