1. A flow diversion device for controlling fluid flow in a delivery system to deploy a prosthetic heart valve device, the flow diversion device comprising:
a housing including:
a plurality of channels; and
a plurality of openings in fluid communication with the plurality of channels, wherein the plurality of openings includes a first opening and a second opening; and
a flow control component movable to selectively form a plurality of pathways including a first pathway and a second pathway for fluid communication via the plurality of channels between the plurality of openings based on a position of the flow control component, wherein:
when the flow control component is in a first position, the first pathway is formed to allow fluid flow through at least the first opening toward a first chamber of the delivery system to cause deployment of the prosthetic heart valve device, and
when the flow control component is in a second position, the second pathway is formed to allow fluid flow through at least the second opening toward a second chamber of the delivery system to cause recapture of the prosthetic heart valve device.
