The present invention is related to a stretchable tubular device (1) comprising at least one layer (Lx) of a stretchable polymer, a power supply (2) and a set of electrodes (3a, 3b) connected to said power supply (2). The power supply can supply at least a first level of voltage (V1) to the electrodes so as to modify the natural force (F0) of the stretchable layers to a modified force (F1). The present invention also covers a process for manufacturing such a tubular device and its use as a medical implant.
