    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.

    Abstract: Embodiments of the present disclosure relate to a circulatory support device with an integrated cannula. In an exemplary embodiment, an apparatus for attachment to a cardiac pump, comprises an adaptor. The adaptor comprises an annular cross section configured to receive the cardiac pump. The annular cross section is secured to the cardiac pump. The adaptor also comprises a plurality of channels arranged around the adapter and a cannula comprising a proximal portion, a distal portion, and an intermediate portion comprising a braided mesh extending between the distal portion and the proximal portion. The proximal portion has a proximal end comprising a plurality of elements arranged through the channels and the distal portion comprises a plurality of wires and a tip element. The plurality of wires extend in a distal direction from the braided mesh to the tip element and are secured to the tip element. And, a coating covers at least a portion of the braided mesh.
