In this paper we study closed inflationary universe models by means of a tachyonic field. We described a general treatment for created a universe with Ω > 1 in patch cosmology, which is able to represent General Relativity, GaussBonnet or RandallSundrum patches. We use recent data from astronomical observations to constrain the parameters appearing in our model.
