20140343352 | ROTATIONAL PUMP AND METHODS FOR CONTROLLING ROTATIONAL PUMPS - A rotational pump capable of running at a rotational speed (n) having a system for direct or indirect measurement of pressure difference or flow rate across the pump, wherein a control system is designed to calculate an index of pulsatility (PI) of the pressure difference or flow rate, estimating the gradient of PI with respect to the rotational speed (dPI/dn) and regulating the dPI/dn to a pre-defined set-point or regulating the pump in a way that the dPI/dn is minimal. | 11-20-2014 |
20140316426 | CONNECTION SYSTEM FOR THE DETACHABLE FIXATION OF A HOLLOW CYLINDRICAL COMPONENT AT A RECESS - An easily detachable connection of a hollow cylindrical component, such as a graft, at a recess in tissue, such as a heart or a blood vessel, an annular element, a guide element and a spring element are provided, which are secured by way of a suture ring at the body part and at the hollow cylindrical component, and which permit an easily disengagable mutual locking by way of the spring element. To this end, the annular element comprises a groove extending around the periphery thereof, into which the spring element plunges for locking. | 10-23-2014 |
20140276326 | CONNECTION SYSTEM FOR CREATING A CONNECTION CHANNEL FOR BODILY FLUIDS - A connection system for creating a vascular cannula for connection to a blood vessel includes a flexible hose element in the form of a graft, a conduit element and, disposed therebetween, a connecting element extablishing fluid-tight connections, wherein a retaining element is equipped with a radially outwardly elastically beadable snap ring, which, in the connected state, can be snapped in behind a detent surface of one of the parts of the connection system. | 09-18-2014 |
20140205434 | ROTARY PUMP COMPRISING A ROTOR AND DELIVERY ELEMENTS - A rotary pump includes a rotor having delivery elements which deliver at least a portion of a fluid in an axial direction of the rotor. Two delivery elements or groups of delivery elements are provided on the rotor for delivering the fluid, and deliver the fluid to be delivered in mutually opposing axial directions of the rotor, so that the axial thrust components substantially compensate each other. The fluid flows flowing counter to each other jointly give way in the radial direction of the rotor and can be jointly discharged through the volute casing and utilized. | 07-24-2014 |
20140187852 | BLOOD PUMP - A blood pump includes a hollow body in which an impeller with blading is provided for producing an axial propulsion of blood along the impeller. An at least partly actively stabilised magnetic bearing device is provided wherein the impeller may be set into a rotation about a rotation axis of the impeller, with a motor stator. The hollow body has an inlet for the flow of blood into the hollow body in an inflow direction which is essentially parallel to the rotation axis, and an outlet for the outflow of the blood out of the hollow body in an outflow direction. | 07-03-2014 |
20130343917 | VALVE, PUMP SYSTEM AND METHOD FOR OPERATION OF A PUMP SYSTEM - A valve for the control of a fluid flow, with a connection block ( | 12-26-2013 |
20130087040 | CYLINDER HOUSING, IN PARTICULAR PUMP CYLINDER HOUSING - A pump cylinder housing has a hollow cylinder and an end-side cover part, a threaded sleeve may be fixed on the outside of the hollow cylinder, at least three radially outward projections are connected to and distributed on the cover part periphery to the cover part and at least partly pass through recesses of the threaded sleeve. A union nut may be screwed onto the threaded sleeve so that the projections project radially out of the threaded sleeve and bear on an end side of the union nut. The cylinder housing may be assembled by in a simple manner so that the cylinder housing and the cover part may be connected to one another in an exactly colinear and centred manner and thereby may be reliably sealed. The cylinder cover may thereby be positioned in an infinite radial position on the cylinder. | 04-11-2013 |
