It is amazing to think how medical care has advanced over the years. One way to observe this is in the decreasing size of many implantable devices. The world’s first implantable pacemaker, for example, weighed in at around 180g, whereas modern cardiac resynchronization devices are often about 30g and are a similar size to the one-euro coin.
But that’s nothing compared to some recent developments in stent design. On the US market, there is a stent designed for unblocking particularly small blood vessels that is just 2mm in length.
