A blood pump includes a hub having an axis of rotation and a generally cylindrical shape. The hub has an upstream end region, a central region, and a downstream end region, and the hub includes a magnetic material. Blades that are disposed on the downstream end region of the hub extend downstream of the hub.

Pump and method for mixed flow blood pumping

A percutaneous cable is attached to a mechanical cardiac pump and is passed through the skin. Sutures can be used to stabilize the cable against movement to prevent disturbing tissue surrounding cable and thereby reduce the incidence of infection. A funnel-shaped tubular device can be used where the cable exits the skin to allow the cable to flex below or near the skin surface as may be desired to accommodate physical activity of a patient. An anchor can be attached to the cable and implanted below the skin surface to stabilize the cable against movement. The anchor can include any one or a combination of a flat mesh material, a bundle of ultrafine filaments, and a barbed filament.

Assembly and method for stabilizing a percutaneous cable

A blood pump includes a rotor having a flared portion downstream proximate a downstream bearing that supports the rotor. The flared portion of the rotor includes a width greater than a width of an upstream portion of the rotor. A blood pump also includes a housing having an internal wall with a flared portion downstream of a motor stator and proximate a transverse outlet.
