  • Intracardiac blood pump
    Patent number: 6544216
    Abstract: The intracardiac blood pump (10) comprises a drive section (11) and a pump section (12). A flexible pump hose (14) is connected to the pump section (12). To lay the pump hose (14) from the right atrium (21) to the pulmonary artery (26) the distal end of the pump hose (14) comprises a balloon (35) which acts as guide element in the blood flow and is entrained by the natural blood flow. This facilitates placing of the blood pump in the heart.

  • Cannula having constant wall thickness with increasing distal flexibility and method of making
    Patent number: 6007478
    Abstract: A cannula for use as for example on the inflow end of an implantable intravascular heart pump. The stiffness of the cannula is differentiated along its length, wherein its proximal end is stiffer than its distal end, while a substantially constant wall thickness is maintained along its entire length. Attached to the flexible distal end, is a rigid tip component having inlet ports and an interior surface profile that minimizes the risk of hemolysis and thrombogenisis.
