Abstract
A coil assembly comprising a coil of a strand-based material retained in a figure-8 configuration, and having an inner layer and an outer layer, where the inner layer of the coil defines a core region of the coil, and where the coil is configured to unwind loop by loop beginning from the inner layer and moving towards the outer layer as the strand-based material is drawn through a payout hole. The coil assembly also comprises a permeable hub configured to reduce payout entanglement of the strand-based material.
