Abstract
Systems and methods for providing hemodynamic support to a patient with an intravascular blood pump are disclosed. In some implementations, the blood pump includes a motor and an improved motor cable for delivering electrical power to the motor. The motor includes a stator with one or more coils. The motor cable includes one or more electrical conduits. The motor cable also includes a tail portion and a head portion. In some implementations, the head portion may have an O-shape or a C-shape. The motor cable may reduce the complexity of assembling the blood pump. For example, the motor cable may reduce the risk of shorting the one or more coils and/or the one or more electrical conduits.
Claims21
1-20. (canceled)
An intravascular blood pump comprising:
- an inlet area;
- an outlet area, wherein a passage fluidically couples the inlet area and the outlet area;
- a motor to draw blood into the inlet area, channel the blood through the passage, and expel the blood through the outlet area;
- and
- a cable having a tail portion and a head portion, wherein one or more electrical conduits extend through the tail and head portions, wherein the head portion comprises one or more pads and wherein the motor is coupled to the one or more electrical conduits through the one or more pads.
A method for assembling an intravascular blood pump comprising a motor and a cable, the method comprising:
- coupling a head portion of the cable to an internal structure of the intravascular blood pump, wherein the cable further comprises a tail portion, wherein one or more electrical conduits extend through the tail and head portions, and wherein the head portion comprises one or more pads;
- and
- coupling a first lead line and a second lean line of each of one or more coils of the motor to respective ones of the one or more electrical conduits through respective ones of the one or more pads.
