  We study the properties of the kappa meson in the nuclear medium, starting
from a chiral unitary model of S-wave, I=1/2 K-pi scattering, which describes
the elastic K-pi phase shifts and generates a pole in the amplitude. Medium
effects are considered by including pion and kaon selfenergies. We explore the
changes in the kappa pole position and in the K-pi scattering amplitude at
finite density, with two different models for the kaon selfenergy.
