Swiss Scientists Print World’s Smallest Stent

In rare cases, some children, often still in the womb, develop urethral strictures that make it difficult or impossible to empty the bladder. Typically, a surgical procedure is performed to remove the narrowed section of the urethra, with the open ends being sewed together. This is traumatic for the children and can be difficult for […]

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...)

LipoGlo Makes Bad Cholesterol Glow Inside Zebrafish

So-called “bad cholesterol” is a molecular complex of fat and protein. Specifically, the protein is Apolipoprotein-B, or ApoB, and the fat is cholesterol. While ApoB helps fat molecules to move around the blood vasculature, it is also what makes cholesterol stick to vessel walls, forming dangerous plaques that are one of the main causes (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 […]

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...)

Blood Flow Measurement Using Tiny LED Catheter

Measuring blood flow is important during a variety of surgical procedures, as well as in intensive care settings. Typically, this is performed intermittently, so there’s not a lot of temporal detail in the readings. Now, a team of researchers at Flinders University in Australia has developed a proof-of-concept prototype vascular catheter that (Read more...)

Patches Made of Heart Tissue Going to Clinical Trials

Stem cell therapies to heal damaged hearts have proven to be lacking so far, probably because simply injecting new cells into afflicted regions isn’t enough. Researchers from Imperial College London have now created patches made of cardiac tissue to sew over damaged areas of the heart. These patches, which can beat on their own to […]

Philips Unveils IntraSight Multi-Modality Imaging Platform

For years, catheter-based minimally invasive procedures have depended on X-ray imaging to guide physicians toward the treatment site. New tools, including intravascular ultrasound (IVUS) and fractional flow reserve (FFR), which measures blood pressure inside a vessel, are giving physicians additional perspectives. Using these modalities in a single (Read more...)

FDA Approves More Accurate GORE TAG Conformable Thoracic Stent Graft with ACTIVE CONTROL System

Gore just announced winning FDA approval for its GORE TAG Conformable Thoracic Stent Graft with ACTIVE CONTROL System. The thoracic endovascular aortic repair system is based on the Conformable GORE TAG Device, but with a new, more robust control mechanism that helps to position the implant with greater accuracy and confidence. The implant its (Read more...)

World’s First Surgical Vending Machine

Xenco Medical, a company that makes disposable spinal tools and implants, is unveiling a vending machine for tracking and dispensing these devices. Clinicians have a huge touchscreen display to choose what they’d like to retrieve out of the machine. The same display can be used to get some specs on the various devices and watch […]
