PhonoGraft: 3D Printed Tympanic Membrane Graft
Perforations of the tympanic membrane or “eardrum,” the thin membrane that conducts sound in the ear, can result in severe hearing loss and recurring infections. Worldwide, tympanic membrane perforations occur in about 30 million people, with about four million people in North America and the European Union alone, due to blast and other traumatic injuries,... -
Microrobotic Laser-Steering Medical Device for Minimally Invasive Surgery
Endoscopy has proven extremely useful in many areas of medicine because it can be carried out with relatively few risks in a short time, and be used to diagnose and treat numerous diseases. In gastroenterology, endoscopies of the upper gastrointestinal tract (esophagus, stomach, first part of the small intestine; upper GI endoscopies) and lower gastrointestinal... -
Regenerating Tissues with Sustained Growth Factor Delivery
Millions of people worldwide suffer from traumatic injuries or health conditions that cause damage to soft tissues including nerves, muscles, and blood vessels. The body can heal some of that damage, but more serious cases like the severing of a nerve or sustained oxygen deprivation can lead to permanent loss of movement or sensation in... -
Smart Tools: RFID Tracking for Surgical Instruments
Surgeons can use up to 250 different tools during a surgical procedure to perform tasks like cutting, grasping, cauterizing, suturing, suctioning, and reducing bleeding. Each tool must be manually counted by hospital staff both before and after surgery to ensure that none of them have gone missing, which is a tedious and time-consuming process. This... -
Light-Reflecting Balloon Catheter for 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 for Wound Healing
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...

Video/AnimationPhonoGraft: Programming the eardrum to repair itselfEardrum perforations are a widespread problem affecting millions worldwide. Current standard of care is invasive, involves harvesting an autologous tissue to patch the eardrum, and often requires to revision surgeries, while hearing outcomes remain unsatisfying. What if we could program the eardrum to repair itself after injury? Researchers at the Wyss Institute, Massachusetts Eye and... -
Video/AnimationA Laser Steering Device for Robot-Assisted SurgeryResponding to an unmet need for a robotic surgical device that is flexible enough to access hard to reach areas of the G.I. tract while causing minimal peripheral tissue damage, Researchers at the Wyss Institute and Harvard SEAS have developed a laser steering device that has the potential to improve surgical outcomes for patients. Credit:... -
Video/AnimationOrigami Miniature Surgical ManipulatorResearchers from the Wyss Institute, Harvard SEAS, and Sony have created the mini-RCM, a small surgical robot that can help surgeons perform delicate teleoperated procedures on the human body. Credit: Wyss Institute at Harvard University -
Video/AnimationAlginate Hydrogel for AngiogenesisThis video describes how an alginate hydrogel can be used to trigger the formation of new blood vessels at an ischemic site in the body. Credit: Wyss Institute at Harvard University. -
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...
