It is a well-known result of T. Kato that given a continuous path of square matrices of a fixed dimension, the eigenvalues of the path can be chosen continuously. In this paper, we give an infinite-dimensional analogue of this result, which naturally arises in the context of unitary spectral flow. This provides a new approach to spectral flow, which seems to be missing from the literature. It is the purpose of this paper to fill in this gap.
