Abstract: Systems for delivering prosthetic heart valve devices and associated methods are disclosed herein. A delivery system configured in accordance with embodiments of the present technology can include, for example, an elongated catheter body, a delivery capsule carried by the elongated catheter body, and two fluid chambers within the delivery capsule. The delivery capsule can be hydraulically driven between a containment configuration for holding the prosthetic heart valve device and a deployment configuration for at least partially deploying the prosthetic heart valve device. For example, the delivery capsule can be urged towards the deployment configuration when fluid is removed from the first chamber and fluid is delivered into the second chamber, whereas the delivery capsule can be urged towards the containment configuration to resheathe the prosthetic heart valve device when fluid is removed from the second chamber and delivered into the first chamber.

Abstract: Systems for mitral valve repair are disclosed where one or more mitral valve interventional devices may be advanced intravascularly into the heart of a patient and deployed upon or along the mitral valve to stabilize the valve leaflets. The interventional device may also facilitate the placement or anchoring of a prosthetic mitral valve implant. The interventional device may generally comprise a distal set of arms pivotably and/or rotating coupled to a proximal set of arms which are also pivotably and/or rotating coupled. The distal set of arms may be advanced past the catheter opening to a subannular position (e.g., below the mitral valve) and reconfigured from a low-profile delivery configuration to a deployed securement configuration. The proximal arm members may then be deployed such that the distal and proximal arm members may grip the leaflets between the two sets of arms to stabilize the leaflets.

Abstract: Systems for delivering prosthetic heart valve devices can include, for example, an elongated catheter body, a deliver capsule carried by the catheter body, and an expandable atraumatic member. The delivery capsule includes a platform and a housing having an outer wall and a proximal rim, and the platform is configured to be releasably coupled to a prosthetic heart valve device.

The expandable atraumatic member has an atraumatic surface and a peripheral portion. The atraumatic member has a compacted configuration and an expanded configuration in which the peripheral portion extends laterally outward over the proximal rim of the housing to protect tissue of the heart and the vasculature from potentially being damaged by the proximal rim of the housing as the delivery system is withdrawn in a proximal direction through the patient.

The method further includes partially deploying a prosthetic heart valve device from the capsule such that an inflow region of a valve support and an inflow region of a fixation structure are radially expanded. A portion of the prosthetic heart valve device remains coupled to the delivery device while a gap exists between a downstream end of a prosthetic valve disposed within the valve support and a distal terminus of the capsule such that fluid can flow through the prosthetic valve with the prosthetic heart valve device partially deployed. The method may further include recapturing the prosthetic heart valve device within the capsule.
