摘要： 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 housing is configured to slide along the platform from a containment configuration to a deployment configuration. The expandable atraumatic member has an 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heart and the vasculature from potentially being damaged by the proximal rim of the housing as the delivery system is withdrawn in a proximal direction through the patient.

摘要： A repair device (101) for repairing a native mitral valve having an anterior leaflet and a posterior leaflet between a left atrium and a left ventricle comprises a support (110) having a contracted configuration and an extended configuration, and an appendage (135), such as a flap or apron extending from the support. In the contracted configuration, the support is sized to be inserted under the posterior leaflet between a wall of the left ventricle and chordae tendineae. In the extended configuration, the support is configured to project anteriorly with respect to a posterior wall of the left ventricle by a distance sufficient to position at least a portion of the posterior leaflet toward the anterior leaflet, and the appendage is configured to extend beyond an edge of the posterior leaflet toward the anterior leaflet.

摘要： Prosthetic heart valve devices for percutaneous replacement of native heart valves and associated systems and method are disclosed herein. A prosthetic heart valve device configured in accordance with a particular embodiment of the present technology can include an anchoring member having an upstream portion configured to engage with tissue on or near the annulus of the native heart valve and to deform in a non-circular shape to conform to the tissue. The device can also include a mechanically isolated valve support coupled to the anchoring member and configured to support a prosthetic valve. The device can further include an atrial extension member extending radially outward from the upstream portion of the anchoring member and which is deformable without substantially deforming the anchoring member. In some embodiments, the upstream portion of the anchoring member and the extension member may be deformed while the valve support remains sufficiently stable.

摘要： The present technology is a prosthetic heart valve device, and related systems and methods, for treating a native valve of a human heart having a native annulus and native leaflets. One embodiment comprises a valve support having an inflow region and an outflow region, and a prosthetic valve assembly within the valve support. The device further includes an anchoring member having a base attached to the outflow region of the valve support, a plurality of arms projecting laterally outward from the base and inclined in an upstream direction in a deployed state, and a fixation structure extending upstream from the arms. The fixation structure has a plurality of struts that define an annular engagement surface configured to press outwardly against the native annulus and a plurality of fixation elements projecting from the struts. The downstream-most portion of the fixation structure extends from the arms at a smooth bend, and fixation elements at the downstream-most portion of the fixation structure extend in an upstream direction.

摘要： A flow diversion device configured in accordance with embodiments of the present technology may include, for example, a housing including openings to channels that intersect at a junction. The flow diversion device may also include, for example, a flow control component disposed at the junction and movable to selectively form pathways for fluid communication based on a position of the flow control component. For example, when the flow control component is in a first position, a first pathway may allow fluid flow causing deployment of the prosthetic heart valve device and, when the flow control component is in a second position, a second pathway may allow fluid flow causing recapture of the prosthetic heart valve device. The flow diversion device may include a handle movable to position the flow control component in the first or second positions thereby selectively controlling fluid flow of the delivery system.
