Scientists have developed a first-of-a-kind "steerable" catheter that takes inspiration from insects to safely navigate the brain's arteries and blood vessels, which could open up new possibilities for treating hard-to-reach aneurysms.

Scientists have developed a new type of smart stent that can help prevent some of the complications these implants bring. The stent is coated in a substance that minimizes the inflammatory response, while promoting tissue repair.

Heart failure often requires a transplant of the whole organ. Now scientists at EPFL have developed an artificial aorta that can help pump blood, taking some of the pressure off the heart to reduce or even eliminate the need for a transplant.

Blood clots can be dangerous, and blood thinning drugs aren’t always enough to clear them out. Now, researchers at North Carolina State University have demonstrated an ultrasonic “drill” that can break clots apart with the help of tiny nanodroplets.

Scientists in China and Switzerland have teamed up to produce an implantable medical device that mimics the primary function of blood vessels, but goes a number of steps further than its natural counterparts.

Heart attack patients often need replacements for damaged arteries. In a new proof-of-concept study, scientists knitted a prototype graft out of hybrid synthetic and biological yarn, helping the patients own cells grow and repair the artery.

First responders don’t have the same tools that emergency rooms do. Now, Harvard scientists have developed a new blood-clotting material that’s portable and easy to store, potentially helping injured patients survive long enough to reach a hospital.

Studies have seen physical activity slow age-related vision loss, but it hasn’t been clear how causal that relationship has been. New research is now offering the first evidence to show how exercise can directly slow, or prevent, macular degeneration.

New research from the University of Colorado Boulder has offered some of the clearest evidence to date showing how the gut microbiome produces a metabolite that, over time, contributes to age-related declines in cardiovascular health.

A study is offering the first evidence of a causal link between gut bacteria and neurovascular disease. It suggests a microbial metabolite can travel through the bloodstream, reach blood vessels in the brain and expedite the development of lesions.

When a damaged blood vessel has to be replaced, it's important that the replacement be well-tolerated by the body. And while bioprinted blood vessels are one possibility, French scientists are now working on weaving the things out of collagen yarn.

Fighting cancer can sometimes feel like a game of Whack-A-Mole – even after a primary tumor is removed the disease can crop up again in other organs. Now, researchers have developed a drug that can prevent cancer from spreading.
