Elongate instruments, e.g. medical tubes, catheters, cannulas or needles, may be equipped at the front with the extremely small linear motor for generating vibrations or mechanical vibrations of the low-frequency range. It is then possible in a gentler way, including selectively in different foci, also to reach deep into the body for endotherapy, in order to use the linear motor, for example in the large bile duct, even in combination with a nozzle head and also by a fluid such as physiological saline solution, for vibration purposes in this duct even over a fairly long period of time in order to promote flow of bile or to expel stones. The linear motor with its piston and the device for the microfocal generation of mechanical vibrations of the low-frequency range can be used as a valve for the nozzles of a nozzle head, and, if the front part of the piston is appropriately designed, as a tool which can also be removed from the nozzle head from the proximal side for further medical purposes.
