摘要： The invention relates to a pump-inflow-cannula (1) providing a blood conduit from a heart (2) and/or from an associated vessel to an external blood handling system. The pump-inflow-cannula comprises a body (3), encompassing an essentially axially extending inflow-lumen (4), having a distal-end (5) for an attachment of the inflow-lumen (4) to the blood handling system, and having a proximal-end (6) for an introduction of blood from the heart (2) and/or from the associated vessel into the inflow-lumen (4), wherein at least one projection (7) is provided at the proximal-end (6) to deflect a heart muscle from intruding into the inflow-lumen (4), wherein the body (3) of the pump-inflow-cannula comprises a reinforcement-means (8). The invention is also related to a pump-outflow-cannula (19) and to a blood managing system comprising a pump-inflow-cannula and a pump-outflow-cannula in accordance with the present invention.

摘要： A clamp can be used to further secure the connection between a flexible tube and a tubing connector and to eliminate or diminish fluid stasis near the connection interface. The clamp can include a hollow member having a passageway extending through the hollow member, an internal thread in the passageway, and a clamping surface in the passageway. The passageway is configured to receive the flexible tube. The internal thread is configured to engage the flexible tube and has a first diameter. The clamping surface has a second diameter less than the first diameter. A hub may be used as an adapter between the clamp and the tube.

摘要： A catheter (or cannula) is small enough in diameter to be placed minimally invasively into the body of a patient but also can be expanded post-placement to provide a larger-diameter placed catheter that supports fluid flow at a rate higher than is possible through the pre-placement reduced-diameter catheter. The expandable catheter is constructed using one or more shape memory polymers and can include one or more stent-like sections and/or at least part of the cannula formed as folded lobes. Each of the stent-like sections is configured to enhance the flexibility of the section as compared to the other parts of the catheter and thus allow the section to accommodate tight bends and turns when inserted into the body of the patient. The folded lobes are axial folds that constitute at least one section of the cannula, and they unfold upon expansion of the catheter to create a large cross-sectional shape.
