摘要： A pump for mimicking physiological blood flow in a patient is disclosed. The pump works via compression and decompression of a tube, inducing a peristaltic flow within the tube. The compression may be effected by a linear actuator, or alternatively by a pivoting compression member. A one-way check valve ensures flow in a single direction.

摘要： A heart pump assembly includes an impeller blade coupled to a rotor or a drive shaft, a cannula, a distal projection coupled to a distal end of the cannula and a blood inlet having a plurality of apertures. The plurality of apertures is radially oriented and disposed about a circumference of the cannula. The plurality of apertures includes at least a first ring of apertures which are proximal to the distal projection and a second ring of apertures which are proximal of the first ring of apertures. The plurality of apertures can allow the heart pump assembly to continue to function if anatomical structures or tissue become suctioned to a portion of the heart pump.
