  The structure and energy of saddle point (SP) states in 2D superconducting
film of finite width $w$ with transport current $I$ are found in the framework
of Ginzburg-Landau model. We show that very near depairing current $I_{dep}$
the SP state with a vortex does not exist and it transforms to 2D nucleus
state, which is a finite region with partially suppressed order parameter. It
is also shown that for slightly lower currents the contribution of the vortex
core energy is important for SP state with a vortex and it cannot be neglected
for $I\gtrsim 0.6 I_{dep}$. It is demonstrated that in the film with local
current concentration near the bend the energy of SP state may be much smaller
than one in the straight film and it favors the effect of fluctuations in such
a samples.
