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 disengageable 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.

A blood pump has a hollow body in which an impeller with a spiral blading produces an axial propulsion of blood along the impeller, as well as an at least partly actively stabilized magnetic bearing device and a hydrodynamic bearing device for the impeller. The impeller may be set into a rotation about a rotation axis of the impeller with a motor stator located outside the hollow body. 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 which is offset to the rotation axis of the impeller to produce a non-zero outflow angle (&#x3b1;) between the inflow direction and the outflow direction. A total artificial heart can be formed from two such blood pumps.

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 stabilized 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.

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 establishing 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.

Connection system for creating a connection channel for bodily fluids

A connecting element for connecting a blood pump or a cannula to a heart, the connecting element including a sealing element, which is designed to at least temporarily close an opening formed in the cardiac wall and to be opened via insertion of a preferably cylindrical object in the direction of an axis of the opening.
