Heart valve invented in Minnesota allows new kind of heart treatment

Inaugurating a potential blockbuster medical device category, a wire-and-mesh medical device invented in Roseville, Minn., has become the first catheter-delivered implant to get European approval to replace the heart’s mitral valve without open-chest surgery. European approval of Abbott Laboratories’ Tendyne Transcather Mitral Valve is “a very important first step” toward gaining U.S. approval, which would open a device category potentially […]

New technology allows control of gene therapy doses

Scientists at Scripps Research in Jupiter have developed a special molecular switch that could be embedded into gene therapies to allow doctors to control dosing. The feat, reported in the scientific journal Nature Biotechnology, offers gene therapy designers what may be the first viable technique for adjusting the activity levels of their therapeutic genes. The lack of such a basic […]

Experts call for halt to CRISPR editing that allows gene changes to pass on to children

Remember the global outrage four months ago at world-first claims a researcher had used the gene editing tool CRISPR to edit the genomes of twin girls? The molecular scissors known as CRISPR (CRISPR/cas9 in full) allow scientists to modify DNA with high precision and greater ease than previous technologies. Now researchers from the USA, Europe, China and New Zealand have […]
