  • Patent number: 9878087
    Abstract: 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.

  • Patent number: 5171216
    Abstract: A multi-lumen catheter for independent delivery and withdrawal of fluids having an improved leading end to minimize stasis and an improved coupling for connection to externally located infusion and withdrawal tubes. The improved leading end has an ellipsoidally shaped tip with a smooth, uninterrupted surface and, in close proximity to the tip, a port or ports evenly spaced along the length of each lumen in staggered relation between each lumen. The improved coupling is a generally L-shaped, implantable transition device bonded to a percutaneous access device. The overall conformation of the multi-lumen catheter may be either a "U-shape" or an upright "Z-shape." Externally located infusion and withdrawal tubes are in fluid connection with an epidermal end of the transition device and a multi-lumen tube fits snugly over nipples at a subcutaneous end of the transition device.
