This required: - advanced optics solutions to be able to see vessels through an opaque layer of tissue - precision manufacturing to machine micrometer scale features in our needles to make them reliably pierce through the tough dural membrane - and rigorous testing to prove it would all work before we ever tried it in a human for the first time Very proud of our whole team for executing on such a difficult and important problem- but there are many more challenges left to solve, and we're hiring brilliant engineers across the stack to help! no biomed background needed!
