The Ducks announced the deal Tuesday.
Deslauriers spent parts of two seasons from 2008 to 2010 as a backup goalie with the Edmonton Oilers, winning 20 games with a 3.01 goals-against average. The former high draft pick has never reached his NHL potential, spending last season in the AHL.
The Ducks haven't re-signed Ray Emery, who filled in for the injured Hiller during the Ducks' run to the Western Conference playoffs.
The Ducks also acquired speedy center Andrew Cogliano from Edmonton for a second-round draft pick in 2013.
