Abstract: A cutting edge of a punch includes side segments and a central segment disposed between the side segments. When the punch head slides into a hollow blade, the central segment of the cutting edge meets the punch head before the side segments meet the punch head. The central segment starts cutting first, which can help avoid a dog-bone shaped hole when the punch is used on a blood vessel, such as the aorta.

Abstract: 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.

Abstract: A blood pump includes a housing and a rotor within the housing configured to rotate along an axis. The rotor may include a hub, the hub having regions with blades and regions without blades. The regions without blades may have a constant outer diameter and may extend along at least one fourth the length of the hub. The regions with blades may have an increasing outer diameter. Blades may be disposed on a downstream end region of the hub and extend downstream of the hub. Blades may begin approximately halfway along the axial length of a motor stator located about a hub and extend downstream of the motor stator. Blades may have portions that produce axial fluid flow and radial fluid flow with improved flow characteristics.
