A heart valve therapy system including a delivery device and a stented valve. The delivery device includes an outer sheath, an inner shaft, an optional hub assembly, and a plurality of tethers. In a delivery state, a stent frame of the prosthesis is crimped over the inner shaft and maintained in a compressed condition by the outer sheath. The tethers are connected to the stent frame. In a partial deployment state, the outer sheath is at least partially withdrawn, allowing the stent frame to self-expand. Tension in the tethers prevents the stent frame from rapidly expanding and optionally allowing recapture. Upon completion of the stent frame expansion, the tethers are withdrawn.

Systems, devices and methods for transcatheter valve delivery

Embodiments hereof relate to a delivery system for a transcatheter valve prosthesis, the delivery system having an integral centering mechanism to circumferentially center both the delivery system and the valve prosthesis within a vessel at the target implantation site. The centering mechanism may include expandable wings that may be selectively aligned with openings formed through a sidewall of an outer shaft of the delivery system, a coiled wing that may be selectively exposed through an opening formed through a sidewall of an outer shaft of the delivery system, a plurality of elongated filaments extending through a plurality of lumens of an outermost shaft of the delivery system that may be selectively deployed or expanded, an outer shaft that includes at least one pre-formed deflection segment formed thereon, a tool having a deployable lever arm, and/or a plurality of loops deployable via simultaneous longitudinal and rotational movement.

Delivery system having an integral centering mechanism for positioning a valve prosthesis in situ

A prosthetic valve including an inner frame, an outer frame, and a connection assembly interconnecting the frames. The inner frame defines an interior volume for receiving a valve structure within the interior volume. The outer frame surrounds the inner frame. The inner and outer frames are each configured to be transitionable between compressed and expanded conditions. The prosthetic heart valve provides a initial deployed state in which the inner and outer frames are in the expanded condition, and a radial shape of the outer frame is adjustable via the connection assembly to a final deployed state. A shape of the outer frame can be adjusted upon implant to enable radial anchoring at the native annulus, while addressing possible non-uniformities of the native annulus and possible anatomical concerns such as LVOT obstruction.

Adjustable prosthetic heart valve

Embodiments hereof relate to methods of delivering a valve prosthesis to an annulus of a native valve of a heart, the native valve having chordae tendineae. A chordae management catheter is positioned within a ventricle of the heart, the chordae management catheter having a displacement component at a distal end thereof. The displacement component has an annular shape and defines a central lumen therethrough. The displacement component is radially expanded to push chordae tendineae within the ventricle radially outward. A valve delivery system is introduced into the ventricle of the heart via a ventricular wall of the heart. The valve delivery system has the valve prosthesis at a distal portion thereof. The valve delivery system is advanced through the central lumen of the radially expanded displacement component towards the annulus of the native valve of the heart. The valve prosthesis is deployed into apposition with the annulus of the native valve.

Chordae tendineae management devices for use with a valve prosthesis delivery system and methods of use thereof

Embodiments hereof relate to centering devices for use with a valve delivery system and methods of delivering a valve prosthesis within a vasculature. A valve centering catheter is configured for use with a valve delivery system. The valve centering catheter includes a circumferential centering device at a distal portion thereof, and the circumferential centering device defines a central opening there-through when in an expanded configuration. The circumferential centering device is annular or has a C-shaped cross-section. The valve delivery system is tracked through the vasculature until the valve prosthesis is positioned through the central opening of the expanded circumferential centering device. The valve centering catheter may alternatively include a longitudinal centering device which acts as a marker for depth control during delivery of a valve delivery system, which may include an integral circumferential centering device.

Centering devices for use with a valve prosthesis delivery system and methods of use thereof

The delivery systems disclosed herein can create simultaneous movement of an inner and an outer sheath of the delivery system. The delivery systems can generally include a handle assembly and a delivery catheter. In certain embodiments, the inner shaft and the outer sheath can be slidably controlled by a control element in the handle. The handle assembly can include a housing with a thumbwheel acting as the control element. In certain embodiments, movement of the inner shaft and the outer sheath can be caused via a gear-type system. In certain embodiments, the handle assembly can include a rotatable housing. A control element can rotate the housing, which can cause a first boss associated with the outer sheath and a second boss associated with the inner shaft to move in opposite directions.
