DRIVELINE CABLE ASSEMBLY
First Claim
1. A blood pump assembly comprising:
- a blood pump configured for implantation; and
a cable assembly secured to the blood pump for providing power and control signals to the blood pump, the cable assembly including a strain relief assembly and a driveline,the strain relief assembly securing the cable assembly to the blood pump and having 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 defining a compartment and an internal passage that leads to the compartment, andthe driveline housing a plurality of conductors that extend from the driveline through the internal passage and into the compartment.

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.

10. An implantable strain relief assembly comprising:
-
a first member having an annular portion and an opening defined through the annular portion, the first member having a conductor mounting portion that defines a compartment in communication with the opening; and a second member that is more flexible than the first member, the second member having an end region coupled to the annular portion and having an outer surface that is curved along a longitudinal extent of the second member at least along a side of the outer surface, the second member defining an internal passage along the longitudinal extent leading to the opening defined through the annular portion of the first member, the internal passage having a substantially constant diameter along the longitudinal extent, the second member having a wall thickness that decreases along the longitudinal extent. - View Dependent Claims (11, 12, 13, 14)
