  • Patent number: 10946561
    Abstract: A method for making a biocompatible three-dimensional heart valve includes delivering, using at least one delivery unit, a biocompatible fluid substance towards a mold having a mold surface to obtain a coating layer of predetermined thickness that coats the mold surface, where the biocompatible fluid substance includes a plurality of particles; handling the mold and the delivery unit to provide a relative movement with at least three degrees of freedom between the mold and the delivery unit, the mold coated with the biocompatible fluid substance that is delivered to obtain a three-dimensional heart valve having a surface corresponding to the mold surface; removing, using a suction and blowing device, from the mold any surplus particles of the biocompatible fluid substance dispensed to make uniform the predetermined thickness of the coating layer; and pressing a counter mold on the coating layer deposited on the mold after delivering the biocompatible fluid substance.

  • Publication number: 20200246209
    Abstract: Apparatus (1) for rehabilitation of an upper limb of a person comprising a base frame (10) and a kinematic chain (100) connected to each other. The kinematic chain (100) comprises a plurality of rigid links (21-25) connected in series one after the other through a plurality of rotational joints (31-34), each of which having a respective rotation axis (131-134) and arranged to rotatably connect two successive rigid links of the series. The apparatus (1) comprises a plurality of actuation groups (70), each of which associated to a respective rotational joint and configured to generate and transmit a predetermined driving power to the rotational joint associated to it.

  • Patent number: 10654200
    Abstract: An apparatus for making a biocompatible three-dimensional object including at least one delivery unit arranged to deliver at least one biocompatible fluid substance towards a 3D mold having a matrix surface to obtain a coating layer of a predetermined thickness configured for coating the matrix surface. The three-dimensional object may be a heart valve. Furthermore, a handling unit is provided arranged to provide a relative movement according to at least 3 degrees of freedom between the 3D mold and each delivery unit. The 3D mold is arranged to be coated by the delivered biocompatible fluid substance, in order to obtain a three-dimensional object having an object surface copying the matrix surface of the support body.

  • Patent number: 8312764
    Abstract: An apparatus (1) for detecting mechanical features of materials, in particular metal materials, comprising an indenter (10) adapted to be pushed against a sample material (15) in which it penetrates for a depth (h) and responsive to the hardness of the materials same. The apparatus (1) provides means for generating a measured force (F) and a transmission gear (35) which changes the rotational motion of shaft (40) of motor (30) into a linear reversible movement. The force generated is then amplified in a hydraulic way and transmitted to the indenter (10). This solution allows to lighten and to reduce the size of the mechanisms for generating the force, reducing also wear and mechanical backlash, as well as costs and overall dimensions. An advantage is also to measure with precision the stroke of the indenter with corresponding control in precision of the penetration (h) of the indenter in the sample material.

  • Patent number: 7480575
    Abstract: A method for detecting mechanical features of a material, in particular a metal material, provides a preliminary step where a database is created containing a finite number of reference curves (P,h) (52). Such curves are obtained using a finite elements analysis and reproduce the trend of the applied force (P) responsive to the penetration depth (h) during an indentation test. The reference curves (P,h) are obtained for a determined number of different materials having a known elastic modulus E, and values of yield stress (?sn) and strain-hardening coefficient (n) comprised within determined ranges. The tested sample is then arranged at an indenter, for example a ball indenter (52), for being subject to an indentation test. This is started to cause a graduated penetration of the indenter in the material subject to analysis (53). During the indentation test the penetration depth (h) responsive to the penetration force (P) are measured, and a succession of measured couples (P,h) (54) is then recorded.
