Sacrificial Ink Writing Technique for 3D Printed Organs

Researchers at Harvard have developed a way to 3D print vascular channels in large matrices composed of stem cell-derived organ building blocks. The technique could pave the way for 3D-printed organs. Creating human organs using 3D printing would help to address the current shortfall in available transplants. However, to date, this has proved to be (Read more...)

Injectable Hydrogel for Transcatheter Intravascular Embolization: Interview with Dr. Rahmi Oklu, Founder of Obsidio

Obsidio Inc., a medical device company based in Columbia, South Carolina, has developed an embolic hydrogel (called a gel embolic material: GEM) designed to be delivered minimally invasively through a clinical catheter for blood vessel occlusion. Applications include controlling blood flow in vascular injuries and aneurysms, reducing tumor blood su (Read more...)

Edwards ForeSight Brain Oxygenation Sensors FDA Cleared to Pair with Hemosphere Monitor

Edwards Lifesciences won FDA clearance to integrate its ForeSight brain tissue oxymetry sensors with the HemoSphere monitoring platform. While the clearance is really for a connecting cable, the capability allows anesthesiologists to monitor the oxygen saturation of the brain during surgeries and to correlate it with hemodynamic parameters in real- (Read more...)

Cold Plasma to be Tested as Killer of Cancer Cells

Cold plasma is an unusual gaseous substance in which only the electrons are heated to thousands of degrees, with the rest of the material remaining at room temperature. Purdue University researchers have advanced this field and have helped to make it ready for clinical applications, since cold plasma has the ability to kill target cells […]

Neurons Grow on Crosslinks of Carbon Nanotubes

Carbon nanotubes have a host of interesting properties. They are biocompatible and electrically conductive, so have been investigated as a possible material for growing nerve tissues. To make carbon nanotubes cooperate as desired, novel forms are required and researchers at SISSA (International School for Advanced Studies) and University of Trieste (Read more...)

Biomaterial Tricks Immune System to Grow New Blood Vessels

Researchers from Harvard’s Wyss Institute have developed a new biomaterial that can activate T cells to promote vascularization of ischemic tissues. Their work demonstrates that the biomaterial results in local blood vessel development, increased perfusion, and new muscle growth after ischemia. Various compounds have been tested to try to imp (Read more...)

Magnetically Controlled Soft Robots to Operate on Human Body

Although a myriad of robots is already used in a variety of industries, including medicine, they’re almost exclusively rigid devices using conventional mechanics. To best work with the pliability of the human body, it may be advantageous for medical robots to be soft and not include gears, motors, and metal cables. Researchers at North Caroli (Read more...)

3D Printed Cardiac Components

Researchers at Carnegie Mellon University have developed a method to 3D print collagen and cells to form organ components, potentially paving the way for full organ printing in the future. The technique, called Freeform Reversible Embedding of Suspended Hydrogels (FRESH), involves printing collagen layer-by-layer in a bath of support gel, which all (Read more...)

PrisMax for Continuous Renal Replacement Therapy FDA Cleared

Baxter won FDA clearance for its PrisMax system and accompanying TherMax blood warmer. The system is designed for delivery of continuous renal replacement therapy to treat those with acute kidney injury and some autoimmune diseases. The system is an evolution of the company’s Prismaflex technology that has been available for a few years, and (Read more...)

Tiny Robots Aim to Work Inside Our Bodies

If we’re to have robots that work inside our bodies to find and cure diseases, they must be very small. To help make the dreams of futurists a reality, researchers at Georgia Tech have now created a robot that weighs only five milligrams and is no taller than the side of a US penny. The […]

Using Microparticles to Measure Oxygen in Tissues

The field of tissue engineering is rapidly progressing, in large part thanks to hydrogel scaffolds that provide a comfortable home for new cells. A major issue that researchers bump against is tracking how well oxygen reaches freshly grown cells within such scaffolds, which can indicate how well the new cells are generally functioning. Now, researc (Read more...)

Smart Bandage Pulls Skin Together to Speed Healing

Wounds on the skin are usually treated with bandages that protect the area and keep it moist, but which don’t actively help to promote healing. Researchers at Harvard and McGill universities have now created a mechanotherapy bandage that actually works to close the wound, keeps it protected from microbes, and speeds up healing much faster [&h (Read more...)
