    摘要： In a prosthetic heart valve comprising a generally annular stent and at least two obturators mounted in the stent so as to be above to pivot between an open position and a closed position, the stent is provided with at least one element which projects inwardly of the stent itself, while each of the obturators has recesses which cooperate with the projecting element of the stent with clearance in a generally-hinged configuration which enables the obturators to pivot between the open position and the closed position.

    摘要： There are disclosed devices for conditioning a blood flow which include at least one element with portions which are exposed to the blood and are deformable cyclically at a frequency comparable to the frequency of the heartbeat, in which the cyclically deformable portions have a continuous coating of biocompatible carbonaceous material comprised of carbon crystals having a density of greater than 2.1 grams per cubic centimeter applied by sputtering directly on and completely covering at least those portions of the device which are exposed to the blood.

    摘要： Described herein is a pulsator device that can be used for generating a pulsed flow starting from a substantially constant flow, for example in reactors for cell growth and other applications in which it is desired to have available pulsed irroration flows. The device comprises a deformable body that is able to define a duct for passage of a substantially constant flow of a fluid subjected to pumping. Associated to the deformable body is at least one actuation chamber that is selectively expandable between at least one contracted condition and at least one extended condition of pumping so as to produce a variation of the section for passage of said fluid through the duct. The variation of the section of passage through the duct is able to cause the generation of a pulsed flow of the fluid subjected to pumping.

    摘要： A duct for carrying blood for ventricular-assistance devices (VADs) has a tubular body and an end having associated thereto a valve for enabling the flow of blood unidirectionally in the duct. The valve has an annular reinforcement, and the end of the duct is provided with a slot for receiving the annular reinforcement of the valve with the reinforcement in a retracted position in said slot. The aforesaid end and the aforesaid tubular body of the duct are provided with a continuous coating of haemocompatible material, such as a polyurethane.
