Soft Robot Biodegrades Inside Body

Researchers at the City University of Hong Kong have developed a magnetic soft millirobot that can grab and release objects, and move around by rolling. The device can be controlled using magnetic fields, and consists of a biodegradable gelatin and iron oxide microparticles. The technology has significant potential as a minimally invasive drug deli (Read more...)

Granular Hydrogels for Improved Bioinks

Researchers at Penn State have developed a granular hydrogel that contains both hydrogel microparticles and self-assembling nanoparticles, and which could be highly suited for bioprinting purposes. The concept involves the nanoparticles becoming adsorbed onto the hydrogel microparticles and reversibly adhering the microparticles together, providing (Read more...)

Smart Socks Help Prevent Falls Among At-Risk Patients

Researchers at the Ohio State University Wexner Medical Center have tested the PUP (Patient is Up) Smart Socks, developed by a medtech company called Palarum, in their ability to reduce falls among at-risk patients. The socks contain pressure sensors that alert caregivers when a patient is attempting to stand up. This can include situations such [& (Read more...)

AR Headset Helps Surgeons Place Implants: Interview with Louie Vogt of Enovis Surgical

Enovis, a medtech company based in Delaware formerly known as DJO, recently announced the launch of ARVIS (Augmented Reality Visualization and Information System), an augmented reality technology that is designed to assist surgeons during implant placement in the hip and knee. The hands-free technology consists of an eyepiece that is mounted on a s (Read more...)

Tough Ultrasound-Controlled Bioadhesives

Scientists from McGill University in Canada created a technique of using ultrasound-mediated cavitation to make bioadhesives better stick to body’s tissues, including wet surfaces that are typically challenging for such materials. The new method involves ultrasound to create microbubbles within the adhesive. The bubbles burst, which then temp (Read more...)

Bacterial Microrobots Deliver Drug Payload to Tumors

Scientists at the Max Planck Institute for Intelligent Systems in Germany have developed tumor-targeting microrobots using bacteria. The team exploited the tendency of bacteria to naturally gravitate towards areas of low oxygen and low ph, which both tend to occur in the vicinity of a tumor. Once near the tumor, the bacteria aggravate the immune [& (Read more...)

TORdx LUNG Test for Donor Lung Assessment: Interview with Eric Brouwer, Chief Scientific Officer at SQI Diagnostics

SQI Diagnostics, a medtech company based in Canada, is developing the TORdx LUNG Test. The technology is intended to assist clinicians in assessing donor lungs in their suitability for transplantation. At present, clinicians typically assess donor lungs using qualitative variables, such as donor health and lung size. One of the most important facto (Read more...)

Improving Transplant Survival with Organ Preservation Tech: Interview with Dr. Anderson, CEO of Paragonix

Paragonix Technologies, a medtech company based in Massachusetts, created the SherpaPak, an FDA organ transportation device that is intended to keep donor organs safe and viable on their journey to a transplant recipient. As the viability of a donor organ can mean life or death for the receiving patient, it makes sense to take exceptional [… (Read more...)

Soft Bioresorbable Implant Controls Pain by Cooling Nerves

A team of engineers at Northwestern University led by John Rogers, the person responsible for many advances in flexible electronics, created a drug-free implant that can control pain by cooling nerves. The soft implant is intended to be wrapped around a nerve during surgical procedures that would typically involve opioid-based analgesia afterwards. (Read more...)

Magnetic Steering System for Guidewires

Percutaneous coronary intervention is an incredibly useful technique to minimally invasively investigate and treat cardiac issues, such as blockages in the coronary arteries, but it requires a significant amount of skill to perform safely and effectively. Manipulating a guidewire through the tortuous vasculature is not for the faint hearted, with t (Read more...)

One-Step Manufactured Meta-Bots with Medical Potential

Engineers at the University of California Los Angeles have developed “meta-bots,” which are fingernail sized robots that can move, sense, and navigate their environment. Strikingly, the robots are essentially ready for use when they emerge from the 3D printer, and consist of piezoelectric actuators that can respond to or generate electr (Read more...)

Perfusion Machine Restores Donor Liver for Transplant

Clinical researchers at the University of Zurich in Switzerland have created a perfusion machine to store donor livers before transplant. We originally reported on the machine back in 2020, but now the team has announced that they stored and treated a damaged liver in the machine, which would ordinarily not be suitable for transplantation. After [& (Read more...)

Tiny Robot Crab to Perform Tasks Inside Body

Engineers at Northwestern University have developed a tiny remote controlled crab robot. The device is just half a millimeter wide, and can perform a variety of impressive tasks, including jumping, twisting, bending, turning, and walking. The tiny devices do not require electricity and instead are powered through heating using a laser. The shape-me (Read more...)

New Antimicrobial Surface for Implantable Devices

Researchers at the University of California Los Angeles have created a zwitterion polymer coating for in-dwelling medical devices, such as urinary catheters, that prevents microbes from adhering and creating troublesome biofilms. Recurrent infection and biofouling are a serious problem for such devices, leading to the overuse of antibiotics and the (Read more...)

Glucose Fuel Cell to Power Medical Implants

Scientists at MIT created a glucose fuel cell that is small and powerful enough to conceivably power medical implants using the sugar present in our blood. The ultrathin device relies on a ceramic material as an electrolyte and platinum anodes/cathodes. The researchers were able to place just over 150 fuel cells onto a chip and […]

Cryoablation for Treatment of Heavy Menstrual Bleeding: Interview with Ric Cote, CEO of Channel Medsystems

Channel Medsystems, a medtech company based in California, created the Cerene cryotherapy device for the treatment of heavy menstrual bleeding. Heavy menstrual bleeding can affect quality of life for many women, and the condition can be associated with abdominal pain, cramping, and tiredness.     The Cerene technology aims to provide (Read more...)

Wireless Implant for Anti-Cancer Photodynamic Therapy

Researchers at Texas A&M University created a wireless device that aims to illuminate and destroy residual tumor cells left after cancer resection. The device can be used by surgeons to illuminate the tumor bed after resection. It works in combination with a photosensitizer drug that is administered before the procedure and accumulates in tumor (Read more...)
