An implantable blood pump includes a housing defining an inlet opening and an outlet opening. Within the housing, a dividing wall defines a blood flow conduit extending between the inlet opening and the outlet opening of the housing. The blood pump has a rotary motor that includes a stator and a rotor. The stator is disposed within the housing circumferentially about the dividing wall such that the inner blood flow conduit extends through the stator.本發明揭示一種可植入式血液泵浦，其包含界定一入口孔及一出口孔之一外殼。在該外殼內，一分隔壁界定延伸於該外殼之該入口孔與該出口孔之間之一血液流動導管。該血液泵浦具有包含一定子及一轉子之一旋轉馬達。該定子係圍繞該分隔壁而圓周地安置在該外殼內使得該內血液流動導管延伸穿過該定子。
