Abstract: A device (1) for collecting samples of biological tissue, comprising a needle (3) and a cannula (4), positioned at a distal end (5) of the device (1) and coaxially arranged along an axis (A) and slidable with respect to each other along the axis (A); a covering sheath (6), surrounding the needle (3) and the cannula (4); and an actuating mechanism (7), positioned at a proximal end (8) of the device (1) and connected to the needle (3) and the cannula (4) for moving the needle (3) and the cannula (4) in the sheath (6); wherein the actuating mechanism (7) is connected to the needle (3) and the cannula (4) by respective flexible operation cables (10a, 10b), capable of transmitting axial forces in both directions.

Abstract: A stent comprising a hollow tubular body, for instance made of polymeric material, extending along and about a longitudinal axis between two opposite open axial ends and having a substantially cylindrical lateral wall delimiting a longitudinal inner conduit; the body comprising a plurality of deformable sections arranged in succession along the axis; each section comprises a plurality of longitudinal portions of the lateral wall and a plurality of radial cuts formed through the lateral wall and which separate the longitudinal portions from one another.

Abstract: A device for collecting samples of biological tissue, comprising a needle and a cannula, positioned at a distal end of the device and coaxially arranged along an axis and slidable with respect to each other along the axis; a covering sheath, surrounding the needle and the cannula; and an actuating mechanism, positioned at a proximal end of the device and connected to the needle and the cannula for moving the needle and the cannula in the sheath; wherein the actuating mechanism is connected to the needle and the cannula by respective flexible operation cables, capable of transmitting axial forces in both directions.
