We construct a generalization of the Conley index for flows. The new index preserves information which in the classical case is lost in the process of collapsing the exit set to a point. The new index has most of the properties of the classical index. As examples, we study a flow with a knotted orbit in ${R}^3$, and the problem of continuing two periodic orbits which are not homotopic as loops.
