Black holes with accretion rates that exceed the Eddington rate eject powerful radiatively-driven winds. The photons of the strong radiation field produced by the inner disk inject momentum to the particles of the wind. These particles reach semi-relativistic velocities and interact with the companion star in X-ray binaries. If the black hole rotates, the radius of the innermost stable orbit can be lower than six gravitational radii, and the relativistic effects become quite relevant. In this talk we will present preliminary results of our model for a relativistic treatment of super accreting black holes, taking into account the mass loss via the ejection of winds.
