Abstract: A delivery and gathering system for at least one target point inside a target body part of a patient, the system including: a microrobot aimed at navigating towards the at least one target point, a cap aimed at being secured to a securing body part of the patient, the cap including a channel which enables to introduce elements into the target body part, or enables to remove elements from inside the target body part, a wire connected to the microrobot and to the cap, and a control unit configured to communicate with the cap, the control unit including a user interface enabling a user to remotely control and navigate the microrobot. The system further includes a flexible elongated element configured to cooperate, by sliding, with the wire in order to extend, from the cap, towards the target point.

Abstract: A micro-engine including a rotation structure, the rotation structure including a head portion, a rear portion, and a deformable portion connecting both portions. The deformable portion is deformable in elongation or compression along a main axis and includes a spring element displaying a free end. The free end of the spring element includes at least an abutment member. The deformable portion further includes a wheel-platform which displays a first and a second face, being configured to cooperate with the free end of the spring element in order to transform a back-and-forth movement of the at least one spring element into a rotational movement of the wheel-platform.

Abstract: This device includes a propulsion element including at least one portion deformable in elongation/contraction according to a main axis (X2) connecting a front portion and a rear portion. At least two guide elements adapted to generate, under the effect of an energy supply, a rotation of the propulsion element respectively about a first axis of rotation and about a second axis of rotation transverse to each other and to the main axis (X2) of the propulsion element. A control unit configured to actuate a rotation of the propulsion element about at least one axis transverse to the main axis (X2) in a coordinated manner with a deformation of the deformable element of the propulsion element in elongation/contraction according the main axis (X2).

Abstract: A microrobot configured to move in a viscous material, in particular in an organ of a subject such as a brain, the microrobot having a propulsion structure comprising a head portion, a rear portion and a deformable portion connecting the head portion and the rear portion. The deformable portion is deformable in elongation/contraction along a main axis connecting the head portion and the rear portion. The head portion includes at its surface at least one propulsion cilium, one end of the at least one propulsion cilium being attached to the head portion and the other end of the at least one propulsion cilium being a free end configured to move freely in the viscous material. The propulsion structure further includes a motor configured to actuate sequentially elongation/contraction cycles of the deformable portion.
