Thanks for the article. But then it points to the Betacel, USA 1970s (60 pacemakers implanted by 1973). https://en.m.wikipedia.org/wiki/Betacel https://en.m.wi

Thanks for the article. But then it points to the Betacel, USA 1970s (60 pacemakers implanted by 1973). https://en.m.wikipedia.org/wiki/Betacel https://en.m.wikipedia.org/wiki/Betacel I’m not trying to dismiss a wonderful invention, I just want journalistic integrity. It’s not a first if someone already made a product in 1973.
