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.
