Fluid diversion devices for hydraulic delivery systems and associated methods

A system for delivering a prosthetic heart valve device into a heart of a patient, the system comprising:

• an elongated catheter body including a delivery control component that is hydraulically driven to deploy and recapture the prosthetic heart valve device relative to the heart of the patient;
• a plurality of chambers including a first chamber and a second chamber operable to receive or expel fluid to hydraulically drive deployment and recapture of the prosthetic heart valve device;
• and
• a fluid diversion device including:
• a housing including a first side, a second side, a bore, and a plurality of channels traversing the housing from the first side through the bore to the second side, wherein the plurality of channels is configured to receive a corresponding plurality of tubes that extend from the first side through the bore to the second side of the housing, and wherein the bore extends laterally across the plurality of channels,
• an occlusion member disposed in the bore, wherein rotation of the occlusion member enables selective occlusion of either a first subset of tubes or a second subset of tubes disposed in 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 tubes and a second position that occludes the second subset of tubes for fluid communication in different directions relative to the first chamber and the second chamber to cause deployment and recapture of the prosthetic heart valve device.

A fluid diversion device for controlling fluid flow in a delivery system to deploy a medical device, the fluid diversion device comprising:

• a housing including a plurality of channels configured to receive a corresponding plurality of tubes, and a bore that extends laterally across the plurality of channels;
• an occlusion member disposed in the bore, wherein rotation of the occlusion member selectively occludes either a first subset of tubes from the plurality of tubes or a second subset of tubes from the plurality of tubes;
• and
• an actuator configured to enable rotation of the occlusion member to at least a first position and a second position such that the first subset of tubes and the second subset of tubes are alternatively occluded in the first position or the second position for fluid communication in different directions relative to a plurality of chambers of a delivery device operable to deploy and recapture the medical device.
