摘要： Methods and systems are provided for the circulation of blood using a purge-free miniature pump. In one embodiment, a pump is provided that may comprise a housing including a rotor and a stator within a drive unit. In this embodiment, the pump may establish a primary blood flow through the space between the drive unit and the housing and a secondary blood flow between the rotor and stator. In another embodiment, a pump establishes a primary blood flow outside the housing and a secondary blood flow between the rotor and stator. In yet another embodiment, a method is provided for introducing the pump into the body and circulating blood using the pump.
