Abstract
A blood pump assembly includes a blood pump configured for implantation and a cable assembly for providing power and control signals to the blood pump. The cable assembly includes a strain relief assembly and a driveline. The strain relief assembly secures the cable assembly to the blood pump and has an outer surface that is curved along a longitudinal extent of the strain relief assembly at least along an outer peripheral side of the outer surface. The strain relief assembly defines a compartment and an internal passage that leads to the compartment. The driveline houses a plurality of conductors that extend from the driveline through the internal passage and into the compartment.
Claims32
A cable assembly for attachment to electrical pins of an implantable blood pump, the cable assembly comprising:
- a driveline for providing power to the implantable blood pump, the driveline housing a plurality of conductors having a distal end;
- and
- a plurality of ferrules coupled to the distal ends of the plurality of conductors, the plurality of ferrules configured to perpendicularly couple the electrical pins of the implantable blood pump with the plurality of conductors of the driveline.
A method for providing electrical and mechanical connection to a blood pump, the method comprising:
- forming a strain relief assembly having a curved flexible member and a rigid member, the rigid member defining a compartment;
- feeding a driveline having a plurality of conductors through the strain relief assembly and securing the conductors of the driveline within the compartment of the strain relief assembly;
- connecting the strain relief assembly and the driveline to a blood pump housing such that the plurality of conductors of the driveline are in electrical and mechanical connection with a plurality of pins of the blood pump.
A method of providing strain relief at a blood pump, comprising:
- forming a strain relief assembly having a curvature along a longitudinal extent of the strain relief assembly;
- positioning a driveline within the strain relief assembly;
- and
- connecting the strain relief assembly and the driveline to the blood pump at an outer wall of the blood pump that connects first and second opposing surfaces of the blood pump.
A blood pump assembly comprising:
- a pump housing having an outer surface and defining a hermetically sealed compartment;
- a boss that extends from the outer surface of the pump housing;
- and
- a feed-through component coupled to the boss, the feed-through component having electrical conductors that extend outward from the boss in a direction substantially perpendicular to the outer surface, the electrical conductors being configured to transmit electrical signals between the hermetically sealed compartment and a location outside the hermetically sealed compartment,
- the boss including one or more attachment features configured to secure a driveline to the pump housing.
