In this paper, we study exhaustions, referred to as rho-restrictions, of arbitrary nonelementary Kleinian groups with at most finitely many bounded parabolic elements. Special emphasis is put on the geometrically infinite case, where we obtain that the limit set of each of these Kleinian groups contains an infinite family of closed subsets, referred to as rho-restricted limit sets, such that there is a Poincare series and hence an exponent of convergence delta(rho), canonically associated with every element in this family. Generalizing concepts which are well known in the geometrically finite case, we then introduce the notion of rho-restricted Patterson measure, and show that these measures are non-atomic, delta(rho)-harmonic, delta(rho)-subconformal on special sets and delta(rho)-conformal on very special sets. Furthermore, we obtain the results that each rho-restriction of our Kleinian group is of delta(rho)-divergence type and that the Hausdorff dimension of the rho-restricted limit set is equal to delta(rho).
