1. A fluid diversion device for controlling fluid flow in a delivery system to deploy a prosthetic heart valve device, the fluid diversion device comprising:
a housing including a first side, a second side, a junction, and a plurality of channels traversing the housing from the first side through the junction to the second side, wherein the junction extends laterally across the plurality of channels;
an occlusion member disposed in the junction, wherein rotation of the occlusion member enables selective occlusion of either a first subset of channels of the plurality of channels or a second subset of channels of the plurality of channels; and
an actuator operably coupled to the occlusion member to enable selective positioning of the occlusion member in at least a first position that occludes the first subset of channels and a second position that occludes the second subset of channels for fluid communication in different directions relative to a first chamber and a second chamber of the delivery system.
