The paper aims to investigate the diffusion process of two competing innovative technologies in the health care sector. Novelties in cardiovascular surgery will serve as an example. Using a rather simple modeling approach for the decisions of adopters and suppliers we simulate the evolution of a new market and discuss the effects network externalities and individual learning unfold in different scenarios. Increasing returns to adoption may lead to situations of technological lock in.
