Abstract:
1. A device for introducing a stent into a hollow organ, comprising: an endorobot including a linear magnet, the endorobot adapted to be freely movable in the hollow organ, wherein a stent, uncoupleable from the outside, is secured to the endorobot in a folded-down state and, at a site of use, is adapted to be opened so as to bear firmly on a wall of the hollow organ; a magnet system which covers an area of treatment of a patient and generates a 3D gradient field for remote-controlled movement and orientation of the endorobot; and a coupling mechanism within the endorobot, the coupling mechanism being configured to release the stent secured to the endorobot, wherein the coupling mechanism includes a coupling magnet and a piezo-stack, the coupling mechanism being connected to a hook configured to hold the stent and the coupling mechanism is configured to release the stent upon receipt of a current pulse acting on the piezo-stack.
