Abstract: Multifunctional occlusion crossover devices include features to improve the crossover balloon occlusion technique used during transcatheter aortic valve replacement procedures, for example. The devices include a compliant balloon incorporated with a highly flexible and lubricous sheath system. The balloon is capable of safely occluding from the common iliac artery and down to an access site in the femoral artery. The devices can simplify the CBOT technique and replace multiple devices currently used for the procedure.

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.
