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...)

Cryomesh System for Long Term Pancreatic Islet Storage

Researchers at the University of Minnesota developed a cryopreservation system that allows for long-term pancreatic islet cold storage. Islets can be implanted in patients with diabetes, and can even be curative in this context, but the technique has been hampered by a lack of techniques to store donor islets beyond 24-72 hours. This latest techniq (Read more...)

Magnetic Tentacle Robot Travels Deep into Lungs

Researchers at the University of Leeds in the UK have created a magnetic “tentacle robot” that is just 2 mm in diameter, which they hope will be able to navigate through some of the smallest airways in our lungs. At present, a bronchoscope is used to investigate the lungs, but this cannot pass into very […]

MRI-Guided Magnetic Seeds Heat and Destroy Tumors

Scientists at University College London have developed a highly targeted anti-tumor treatment. The approach involves guiding ferromagnetic thermoseeds to the site of a tumor using the magnetic fields generated by an MRI scanner. The magnetic seeds can then destroy the tumor through localized heating that is induced by an MR-compatible thermoablativ (Read more...)

Laparoscopic Robot Performs First Autonomous Surgery

Researchers at Johns Hopkins University developed and now successfully tested the Smart Tissue Autonomous Robot (STAR), a self-guiding surgical robot that can perform challenging laparoscopic procedures in gastrointestinal surgery, including intestinal anastomosis. The robot can adjust its surgical plan in real time, just as a human surgeon would, (Read more...)

Robotic Spinal Replica for Surgical Planning

A team at Florida Atlantic University has developed a 3D-printed replica of a portion of the human spine, based on patient CT data. The patient-specific construct can be attached and articulated by a robotic platform, and a soft magnetic sensor allows the researchers to gauge intervertebral loads as the spine assumes different postures. The model [ (Read more...)

Maestro Laparoscopy Assistance Platform: Interview with Anne Osdoit, CEO of Moon Surgical

Moon Surgical (formerly MastOR), is a medtech startup based in France. The company has developed the Maestro laparoscopy assistance platform, a two-armed robotic surgical assistant that can hold and manipulate standard laparoscopic instruments. The device is intended to be used at the bedside and provides the surgeon with greater flexibility and co (Read more...)

New Hydrogel Material for Vocal Cord Repair

Researchers at McGill University developed a tough hydrogel that can resist mechanical forces found in the body. However, the material still provides a friendly environment for encapsulated cells to grow and enables the deep perfusion of blood and other tissue fluids. The injectable biomaterial may be useful in repairing tissues that experience con (Read more...)

Catheter-Deliverable Biomaterial Sealants: Interview with Natalie Artzi, Co-founder of BioDevek

BioDevek, a medtech company based in Cambridge, Massachusetts, has developed a biomaterial adhesive that acts to seal internal wounds and incisions. The material is designed to be sprayed through a catheter, and the primary application for the technology so far is to act as a sealant following colonic polyp resection. At present, following polyp re (Read more...)

3D Blood Vessel Map Reveals Location of Stem Cells

Scientists at Johns Hopkins used a combination of molecular labeling and imaging techniques to create a three-dimensional map of the blood vessels in the mouse skull. Their approach also reveals niches where stem cell populations lurk, which could help researchers to understand how blood vessels and cells behave in various states of disease or inju (Read more...)

Voxel-Based Technique to Streamline Bioprinting

At the University of Virginia researchers developed a new bioprinting technique based on voxels. Voxels are 3D cubes that form basic building blocks in computer graphics, similar to what pixels are for 2D, and have been popularized by games such as Minecraft. The new technique involves printing discrete spherical blobs of bioink (as the voxels) [&h (Read more...)

Simple Color Change Test Identifies Wound Infections

Researchers at the University of Bath in the UK, along with outside collaborators, have developed a simple color change test that rapidly indicates whether a wound is infected with harmful bacteria. The test works by detecting virulence factors released by the bacteria, which prompt a simple color change in a solution. The test could help [… (Read more...)
