    Abstract: A connection system for an implantable blood pump including a pump housing having an impeller disposed therein and a motor housing including a motor disposed therein, the motor housing spaced a distance from the pump housing. A flexible outer sheath couples the pump housing to the motor housing, the outer sheath defining a maximum total length between 7 and 10 centimeters. An inner shaft is coaxial with the outer sheath and couples the motor to the impeller.

    Abstract: A blood pump including a housing defining a fluid flow path, an upstream end, a downstream end, and an outlet at the downstream end. A rotor is disposed within the housing and within the fluid flow path, the rotor being rotatable independent of the housing in a first direction and configured to pump blood downstream toward the outlet. The housing defines an inflow cannula at the upstream end, the inflow cannula defining a proximal end proximate the rotor and an opposite distal end. The inflow cannula defines a major longitudinal axis and minor longitudinal axis, the distal end of inflow cannula defines a plurality of slots radially disposed about the distal end, the plurality of slots being at least one from the group consisting of sloped in the first direction with respect to the major longitudinal axis and angled in the first direction with respect to the minor longitudinal axis.

    Abstract translation: 一种血泵，其包括限定流体流动路径，上游端，下游端和下游端处的出口的壳体。 转子设置在壳体内并且在流体流动路径内，转子可独立于壳体沿第一方向旋转，并构造成将血液向下游泵送到出口。 壳体在上游端限定流入套管，流入套管限定靠近转子的近端和相对的远端。 流入套管限定主纵向轴线和次纵向轴线，流入套管的远端限定围绕远端径向设置的多个槽，所述多个槽至少一个选自沿第一方向倾斜的多个槽和 相对于主纵向轴线并且相对于次要纵向轴线在第一方向上成角度。
