    Abstract: Apparatus and methods are described including a delivery catheter and a delivery tube configured to extend from outside a subject's body into the subject's left ventricle via the delivery catheter. A locking unit is configured to couple to a proximal end of the delivery catheter and the delivery tube is configured to pass through the locking unit. The locking unit includes at least one internal seal configured to surround the delivery tube and to inhibit backflow of blood of the subject, from the delivery catheter, through the locking unit. The locking unit also includes a clip, which has only two states, which consist of a closed state, in which the clip grips the delivery tube so as to inhibit movement of the delivery tube relative to the delivery catheter, and an open state, in which the clip does not grip the delivery tube. Other applications are also described.

    Abstract: Apparatus and methods are described for use with a venous system of a subject that includes one or more tributary vessels that flow into a vein at junctions. A blood-pump-catheter includes a material configured to be placed at a downstream location that is downstream of the junctions and to at least partially occlude blood flow through the vein. The material defines a blood-outlet opening. A blood pump pumps blood from a region of the vein that is adjacent to the junctions, and through the blood-outlet opening. A blood-flow pathway directs upstream venous blood flow from an upstream location that is upstream of the junctions, to downstream of the material, without the upstream venous blood flow being pumped by the pump. Other applications are also described.
