The invention relates to a manufg. process of a flexible conducting film including the following successive stages: to prep. a suspension including of the carbon nanotubes (24) and the chains (26) of a linear polymer, each one of the aforesaid chains carrying a succession of functional groupings (28) of which some at least comprise combined groupings pi (30); and to filter vacuum the first suspension to obtain a film of chains on which the nanotubes by interaction wee are dependent. The invention relates to a device that is to be implanted in vivo and includes a stent (46) surrounded, at least partially, by at least one flexible conductive film (54, 56) contg. chains of a linear polymer, each of which has carbon nanotubes connected thereto via pi-pi interactions. Said film is functionalized by enzymic grafting so as to form an electrochem. bioreactor element. [on SciFinder(R)]
