A meta-analysis of five randomized controlled trials found that performing endovascular therapy with stent retrievers was safe and effective in managing acute ischemic stroke and led to a significant improvement in functional clinical outcomes compared with standard therapy.

Medtronic agreed to acquire Lazarus Effect, a medical device company with an acute ischemic stroke product that is approved in Europe but not in the U.S. The deal, which is subject to customary closing conditions, is an all-cash transaction valued at $100 million.
