Catholic Church has even developed an own ritual for the exorcism.
The Roman Rites Register dated 1614 is a classical guide for exorcism that is still applied today. It contains prayers, bible recitations ,litanies and formulas of banishment. Demons as well as angels are invisible for the human eye. But Both can assume a shape or slip into the body of an animal or a man. When the demon has taken possession of a man, then it will be spoken of a demonic possession. The expulsion of demons out of a man is called exorcism and is spread throughout all religions.
Exorcism belongs to the tasks of shamans and medicine men.
