Publication number: 20080045779Abstract: 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.Type: ApplicationFiled: July 18, 2007Publication date: February 21, 2008Applicant: NEWCORTEC S.R.L.Inventors: Stefano RINALDI, Maurizio ZAGARA, Manlio FIERLI, Gloria PESCE DELFINO, Mauro ERCOLANI

Publication number: 20060236756Abstract: 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.Type: ApplicationFiled: December 22, 2005Publication date: October 26, 2006Applicant: Tecnobiomedica S.p.A.Inventors: Stefano Rinaldi, Maurizio Zagara, Luigi Carotenuto

Publication number: 20040267085Abstract: 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.Type: ApplicationFiled: April 6, 2004Publication date: December 30, 2004Applicant: Ministero dell'lstruzione, dell'Universita e della RicercaInventors: Maurizio Arabia, Mauro Ercolani, Manlio Fierli, Francesco Minoletti, Stefano Rinaldi, Maurizio Zagara

Patent number: 6572642Abstract: A prosthesis having an apertured structure is located in a chamber (11) which is taken to sub-atmospheric pressure. Once sub-atmospheric pressure has been reached, a liquid, optionally containing pharmacological agents, is introduced into the chamber. Drawn by the sub-atmospheric pressure, the liquid saturates the apertured structure of the prosthesis. In this way, the invention eliminates the risk of air being trapped in the apertured structure that could give rise to the formation of blood clots after implantation of the prosthesis. The liquid can contain drugs that penetrate the prosthesis, performing their therapeutic action locally and over time after implantation.Type: GrantFiled: April 30, 2002Date of Patent: June 3, 2003Assignee: Sorin Biomedica Cardio S.p.A.Inventors: Stefano Rinaldi, Arnaldo Giannetti, Enrico Pasquino

Patent number: 6569079Abstract: 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.Type: GrantFiled: April 27, 2001Date of Patent: May 27, 2003Assignee: Ministero dell'Universita e della Ricerca Scientifica e TecnologicaInventors: Maurizio Arabia, Mauro Ercolani, Manlio Fierli, Stefano Rinaldi, Giorgio Sorcini, Maurizio Zagara

Patent number: 5830134Abstract: Physico-chemical parameters, such as pH, pO.sub.2, pCO.sub.2, % O.sub.2, sat, etc., are determined with the use of a sensitive medium, such as a chromophore, having at least one optical property the profile of the spectrum whereof over a predetermined wavelength spectrum of optical radiation varies as a function of the parameter to be determined. The profile of the spectrum is analysed, for example by means of polychromatic sensor means acting on the medium's spectrum, which is preferably substantially continuous, so as to enable the analysis to be carried out with the aid of a profile-recognition function by typical pattern-recognition operations. The determination is thus rendered largely independent of numerous perturbing factors such as those resulting from the use of partially disposable monitoring units, thus eliminating the need for calibration steps.Type: GrantFiled: October 4, 1996Date of Patent: November 3, 1998Assignee: Sorin Biomedica Cardio S.p. A.Inventors: Giuseppe Caputo, Giampiero Porro, Stefano Rinaldi

Patent number: 5728069Abstract: A device for the pulsed pumping of liquids, particularly blood, has a body in which are formed a pumping chamber in which a pulsed flow is imparted to the liquid, an inlet duct upstream of the pumping chamber and communicating therewith, and a delivery duct downstream of the pumping chamber and communicating therewith. Two valve members constituted by lip valves are provided for regulating the one-way flow of fluid in the body from the inlet duct to the pumping chamber and from the latter to the delivery duct. Low levels of hemolysis can be achieved, if the device is pumping blood. Moreover, the device has a low production cost and is quiet. The pumping device may be incorporated into a cardiopulmonary bypass device which includes a venous reservoir, a heat exchanger and an oxygenator.Type: GrantFiled: February 2, 1996Date of Patent: March 17, 1998Assignee: Dideco S.p.A.Inventors: Franco Montevecchi, Fabio Inzoli, Stefano Rinaldi
