We define some rings of power series in several variables, that are attached to a Lubin-Tate formal module. We then give some examples of $(\varphi, \Gamma)$-modules over those rings. They are the global sections of some reflexive sheaves on the $p$-adic open unit polydisk, that are constructed from a filtered $\varphi$-module using a modification process. We prove that we obtain every crystalline $(\varphi, \Gamma)$-module over those rings in this way.
