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: An intragastric balloon comprises a bag body, provided with an internal cavity shaped to contain a filling fluid, and a valve having a valve body provided with a through inner conduit for feeding the filling fluid into the cavity; the valve body is flexible and elastically deformable, being made of an elastic material; and is arranged inside the bag body and shaped so as to elastically deform until it occludes the conduit following a pressure exerted on an outer surface of the valve body by the filling fluid contained in the cavity.

Abstract: A craniostat for an extraoral dental radiographic apparatus includes an upper portion connected to a lower portion by rods. The upper portion includes a crossbeam and rests for a patient's temples, the rests being formed by two arches articulated with the crossbeam. The arches lean on the patient's temples, and are blocked by a control system, which, in one embodiment, is configured as oscillating levers. The blocking action is caused by shape friction generated at the time of activation via the control levers. A method of use of a craniostat is also described.
