Abstract: The present invention relates to a medical device (10), preferably a micro robot for application inside a body, preferably for application inside a human body (2). The medical device (10) includes a body part (11) and a tail part (12). A controlling line (13) is attached to the tail part (12). The controlling line (13) has a tensile strength sufficient to pull back the device from a target location and/or control its velocity and column strength not sufficient to push the medical device (10).

Abstract: A system (10) for moving an intravascular medical device (85) in a vascular network (V) comprises a magnetic actuator (40), a controlling unit (50) and a controlling line driver (60). The controlling line driver (60) is adapted to hold and/or to release a controlling line (70) attached to the medical device (85) at different speeds. The magnetic actuator is adapted to generate a magnetic field (41) at a predetermined location in order to pull the medical device (85) in a pre-determined direction. The controlling unit (50) is adapted to balance at least three forces applied on the medical device (85) and to operate the magnetic actuator (40) and/or the controlling line driver (60).

Abstract: The present invention relates to an electrospun fully biodegradable vascular valved prosthesis, allowing tissue regeneration and growth potential optionally comprising a bifurcation, preferably T-shaped, a mandrel for electrospinning said vascular valved prosthesis, and a method for electrospinning said vascular valved prosthesis.

Abstract: A method for preparing a polymeric material doped with at least one first metal element and at least one second metal element, including: a) copolymerization of a first monomer containing a first metal element and of a second monomer containing a chelating group of a second metal element, to obtain a polymeric material containing (i) recurrent units deriving from the polymerization of the first monomer, the recurrent units containing the first metal element and (ii) recurrent units deriving from the polymerization of the second monomer, the recurrent units containing chelating groups of a second metal element, and when the first metal element is different from the second metal element, b) contacting the material from a) with a solution containing the second metal element, in return for which the second metal element is complexed with the chelating groups, where b) is optional when the first and second metal element are identical.

Abstract: The invention relates to a method for preparing a polymeric material doped with at least one first metal element and at least one second metal element, said at least one first metal element and said at least one second metal element being identical or different from each other, said method comprising: a) a step for copolymerization of at least one first monomer comprising at least one first metal element and of at least one second monomer comprising at least one chelating group of at least one second metal element, in return for which a polymeric material is obtained comprising recurrent units from the polymerization of said first monomer, said recurrent units comprise said at least one first metal element and comprising recurrent units from the polymerization of said second monomer, said recurrent units comprising chelating groups of at least one second metal element; and when said first metal element is different from said second metal element, said method further comprising a step b) for putting the mat
