Having rotated off the board of directors a number of years back, I find myself able to participate in the sessions in a more robust way than previously. There are new technologies, existing ones that are iteratively improved, emerging concepts for classic diseases, and many other topics that continue to come to the fore.For the entirety of my career, I've watched neurointerventional (NI) surgery grow in strength, scope, and power.
