We show thatK-homologous dierential operators on an oriented, Riemannian manifold M can be connected by a \controlled path" of operators. The analytic properties of these paths allows us to measure a winding number (in the sense of de la Harpe and Skandalis). To aid in the exposition we develop a variant of Baum's (M;E;f) model for K-homology. Our model removes the need for Spin c structures in the description of geometric K-homology.
