Abstract: An atherectomy system includes a drive assembly and an advancer assembly. The drive assembly, which may be reusable, includes a drive motor having an output shaft and a first coupler segment that is secured relative to the output shaft. A controller may be adapted to regulate operation of the drive motor. The advancer assembly, which may be single use, includes a flexible drive cable that is adapted to be releasably securable to the first coupler segment. The advancer assembly includes gearing that is secured within the advancer assembly and is operably coupled with the flexible drive cable. A burr catheter is coupled with and extends distally of the gearing. The advancer assembly is adapted to enable relative translation of the burr catheter in order to advance and withdraw an atherectomy burr rotatably secured to a distal end of the burr catheter.

Abstract: A percutaneous circulatory support device includes a housing and an impeller disposed within the housing. The impeller is configured to rotate relative to the housing to cause blood to flow through the housing. A motor is operably coupled to the impeller, and the motor is configured to rotate the impeller relative to the housing. A catheter is coupled to the motor, and a pressure sensor is coupled to the catheter and disposed proximally relative to the housing.

Abstract: Mechanical circulatory support devices with cord management systems are disclosed. An example percutaneous circulatory support device comprises a catheter including an elongate shaft and a percutaneous blood pump positioned at a distal end of the elongate shaft. A junction box is secured to the elongate shaft proximal of the percutaneous blood pump, and a clip assembly is disposed on an outer surface of the junction box.

Abstract: Various aspects of the present invention are directed towards apparatuses, systems, and methods that may include a blood pump. The blood pump may include an impeller assembly housing, an impeller assembly having an impeller configured to cause blood to flow through the pump, a motor housing, a motor configured to drive the impeller, and a pivotable housing connector.

Abstract: Embodiments in the present disclosure relate to an anchoring and centering device for a circulatory support pump. An exemplary apparatus comprises an expandable anchoring device extending along a longitudinal axis, wherein the expandable anchoring device is arranged about a central axis. A distal portion of the expandable anchoring device defines an annulus through which the cardiac pump can be arranged and to which the cardiac pump can be releasable coupled. A proximal portion of the expandable anchoring device is configured to circumferentially expand to an unconstrained configuration that has a cross-sectional diameter greater than a diameter of the annulus. The exemplary apparatus also includes a constraining member arranged over the expandable anchoring device to constrain the expandable anchoring device in a constrained configuration for delivery of the anchoring apparatus.
