A modular valve prosthesis includes an inflow stent, a valve component including a valve stent and a prosthetic valve, and an outflow stent. In a radially compressed delivery configuration, an inflow end of the valve stent is separated from an outflow end of the inflow stent and an outflow end of the valve stent is separated from an inflow end of the outflow stent. In a radially expanded deployed configuration, the inflow end of the valve stent is in contact with the outflow end of the inflow stent and the outflow end of the valve stent is in contact with the inflow end of the outflow stent. A delivery system includes a capsule including first, second and third sections and flexible first and second bands between respective sections. The modules of the modular valve prosthesis are aligned with the sections and gaps between the modules are aligned with the bands.

Modular valve prosthesis, delivery system, and method of delivering and deploying a modular valve prosthesis

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

Devices, systems, and methods for crimping a medical device are disclosed. More specifically, the present disclosure relates to devices, systems, and methods for reducing the diameter of a collapsible heart valve prosthesis to be loaded onto a delivery device. The devices, systems, and methods using at least one funnel to crimp the heart valve prosthesis and load it onto the delivery system.

Devices and methods for crimping a medical device

Methods for rotationally aligning transcatheter heart valve prosthesis within a native heart valve include percutaneously delivering the transcatheter heart valve prosthesis to the native heart valve, wherein the transcatheter heart valve prosthesis includes at least one imaging marker, receiving a cusp overlap viewing angle image and/or a coronary overlap viewing angle image of the transcatheter heart valve prosthesis within the native heart valve, determining, based on the cusp overlap viewing angle image and/or the coronary overlap viewing angle image and the at least one imaging marker, whether the transcatheter heart valve prosthesis is in a desired rotational orientation, if the at least one imaging marker in the cusp overlap viewing angle image and/or the coronary overlap viewing angle indicates that the transcatheter heart valve prosthesis is not in the desired rotational orientation, rotating the transcatheter heart valve prosthesis until the transcatheter heart valve prosthesis is in the desired rotational orientation.

Transcatheter heart valve prosthesis systems and methods for rotational alignment

A two-component valve prosthesis system includes a docking component and a prosthetic valve component that is configured to be delivered separately from the docking component. The docking component has a compressed configuration for percutaneous delivery within a vasculature and an expanded configuration for deployment within a native heart valve. The docking component includes a tubular skirt, a first annular scaffold attached to a first end of the tubular skirt and a second annular scaffold attached to a second end of the tubular skirt. The first and second annular scaffolds are independent from each other. An intermediate portion of the tubular skirt is unsupported such that neither of the first or second annular scaffolds surrounds the intermediate portion of the tubular skirt. The prosthetic valve component has a compressed configuration for percutaneous delivery within a vasculature and an expanded configuration for deployment within the intermediate portion of the docking component.

Prosthetic valve system having a docking component and a prosthetic valve component

Medical devices and methods for closing an anatomical aperture in a tissue are disclosed. The medical devices can include distal and proximal support structures, which can include a plurality of anchor members. A connection element can connect the distal and proximal support structures, and be configured to twist to create a seal within the medical device. In certain embodiments, a sheath about the medical device can be retracted to expose the distal support structure, which can allow it to revert to an anchoring configuration from a delivery configuration, such that the anchor members can engage an interior surface of the tissue. After twisting the connection element to form a seal, the sheath can be further retracted to expose the proximal support structure, which can allow it to revert to an anchoring configuration from a delivery configuration, such that the anchor members can engage an exterior surface of the tissue.

Flow obstructor and transapical closure device

An endovascular prosthesis includes a tubular body and a mobile external coupling. The tubular body includes a graft material and stents coupled thereto, a forms a lumen therethrough. The mobile external coupling extends outwardly from the tubular body. The mobile external coupling includes a graft material and is generally frustoconically shaped. The mobile external coupling includes a base coupled to the tubular body, a top spaced from the tubular body, and a coupling lumen disposed between the base and the top, wherein the coupling lumen is in flow communication with the body lumen. The coupling graft material is a woven fabric with warp yarn which run generally parallel to a longitudinal axis of the mobile external coupling including a shape memory material.
