Definitions
- the invention relates to a blood pump, and more particularly, the invention relates to a centrifugal blood pump system with a magnetic cable drive assembly for connecting and driving the blood pump with a remote motor.
- Blood pumps used in surgical procedures such as cardiopulmonary bypass (CPB) and coronary artery bypass grafting (CABG) are single-use devices. These blood pumps are generally powered by a reusable motor which drives the pump through a magnetic coupling. However, the reusable motors are not sterilizable . Thus, the motor and attached pump are positioned outside the sterile surgical field at a location away from the patient.
- the disposable pump which is driven by the motor is connected to the patient by long lengths of tubing which transport the patient's blood to and from the blood pump. The long lengths of tubing increase the priming volume of the pump which is the amount of the patient's blood and/or saline which must be drawn into the tubing and the pump to prime the pump before blood begins to be returned to the patient .
- a typical CPB circuit includes several feet of flexible tubing that the patient's blood flows through.
- the patient's blood is generally treated with Heparin. The use of Heparin is preferably minimized because Heparin prevents the blood from clotting.
- FIGS. 1 and 2 An example of a prior art blood pump assembly including a disposable blood pump 10 and a reusable motor 12 is illustrated in FIGS. 1 and 2.
- the blood pump 10 has an axial blood inlet 14 and a tangential blood outlet 16.
- An impeller within the fully enclosed and sterile blood pump 10 moves the blood from the inlet 14 to the outlet 16.
- the pump 10 snaps onto the motor 12 and a magnetic coupling between the pump 10 and the motor 12 is used to transmit the rotation of a motor drive shaft to the pump impeller. After use, the pump 10 is removed from the motor 12 and replaced with a new sterile blood pump 10 for the next patient. Due to the non-sterile condition of the motor 12, the motor 12 and pump 10 must be positioned outside of the sterile surgical field.
- the blood pump system comprises a blood pump having an impeller for moving blood from an inlet to an outlet, and a magnetic coupler connected to the impeller.

In one embodiment of the blood pump system, at least one of the first magnetic coupling and the second magnetic coupling is detachably coupled to the power transmission member . In one embodiment of the blood pump system, at least one of the drive coupler and the pump are sterilizable.
- Another aspect of the present invention involves providing a method of driving a sterile blood pump positioned within a sterile surgical field with a motor positioned outside the sterile surgical field.
- the method comprises the steps of: (a) positioning a sterile blood pump within a sterile surgical field; (b) positioning a non-sterile motor outside of the sterile surgical field; (c) providing a drive coupler having a drive element extending between a first magnetic coupling and a second magnetic coupling; (d) coupling the blood pump to the first magnetic coupling; (e) coupling the motor to the second magnetic coupling; and (f) operating the motor.
