  • VENTRICULAR ASSIST DEVICE AND RELATED COMPUTER PROGRAM PRODUCT
    Publication number: 20080045779
    Abstract: A cardiac ventricular assist device or VAD includes a pumping unit with a variable-volume chamber capable of receiving a mass of blood, and a control unit to control the pumping unit to obtain contraction of the variable-volume chamber, with consequent expulsion of the blood collected in the chamber, and expansion of the variable-volume chamber consequent on the flow of blood into the chamber. A flow line is included, such as a transcutaneous line, for a gaseous flow caused by the contraction and expansion of the variable-volume chamber. A sensor sensitive to the gaseous flow in the flow line generates a flow-meter signal that is indicative of the expulsion and inflow of blood with regard to the variable-volume chamber.

  • Ventricular assist device and accessory therefor
    Publication number: 20040267085
    Abstract: The device comprises a bag associated to which are actuator means which can be selectively activated so as to enable expansion of the bag, with consequent filling of the bag itself by a mass of blood which flows towards the bag, and to produce contraction of the bag with consequent expulsion from the bag itself of the mass of blood that has flowed into the bag. Associated to the bag is a containment casing to which a duct is connected for enabling inflow and outflow of aeriform with respect to the casing as a result of the movement of expansion and contraction of the bag. A pressure limiter is provided for determining selectively and maintaining in a precise way the value of pressure of said aeriform which determines outflow—and possibly inflow—of the aeriform with respect to the aforesaid casing.

  • Ventricular assist device, accessory therefore and method of use
    Patent number: 6569079
    Abstract: A device comprises a bag with associated actuator means which can be selectively activated to permit the expansion of the bag and its consequent filing with a body of blood which flows towards the bag, and to produce the contraction of the bag with the consequent expulsion from the bag of a body of blood which has flowed into the bag. Means are provided for selectively varying the resistance offered by the said bag to filing with the said body of blood.
