Abstract: A system for percutaneous delivery of a stented prosthetic heart valve. The system includes a delivery device with a self-expanding prosthetic heart valve attached thereto and a delivery sheath with an opening on a distal end thereof. The delivery sheath includes a funnel on a proximal end thereof. The delivery device is inserted into the funnel of the delivery sheath. As the delivery device is advanced into the funnel, the expanded heart valve is compressed by the shape of the funnel into a crimped arrangement. The delivery device further advances the heart valve distally within the delivery sheath past the delivery sheath opening. The delivery device is advanced relative to the delivery sheath in transitioning the heart valve from a crimped arrangement to the expanded and deployed arrangement.

Abstract: Embodiments hereof relate to a transcatheter valve prosthesis including a tubular fabric body, a first or inflow tubular scaffold attached to a first end portion of the tubular fabric body, and a second or outflow tubular scaffold attached to a second end portion of the tubular fabric body. A prosthetic valve component is disposed within and secured to an intermediate portion of the tubular fabric body that longitudinally extends between the first and second end portions of the tubular fabric body. The intermediate portion is unsupported such that neither of the first and second tubular scaffolds surrounds the intermediate portion of the tubular fabric body. The intermediate portion may include one or more windows for coronary access and may include one or more commissure reinforcement members coupled thereto to provide support for the prosthetic valve component.

Abstract: An embolic protection device includes a shaft, a first magnet fixedly coupled to a distal portion of the shaft, a second magnet slidingly coupled to the shaft proximal to the first magnet, and a filter including a distal portion coupled to the first magnet and a proximal portion coupled to the second magnet. The first and second magnets are magnetically attracted to each other such that in a radially compressed configuration of the filter, the second magnet is spaced from the first magnet a first distance, and in a radially expanded configuration of the filter, the second magnet slides towards the first magnet such that the second magnet is spaced a second distance from the first magnet, wherein the second distance is smaller than the first distance.

Abstract: The present disclosure relates to delivery devices for transcatheter stented prosthesis loading, delivery and implantation. The delivery devices provide a loaded delivery state in which the stented prosthesis is loaded and compressed over the delivery device. The compression of the stented prosthesis can be adjusted with one or more elongate tension members, which extend around the stented prosthesis and proximately to an actuation and release assembly that can be provided as part of a handle assembly. The delivery device can be manipulated to adjust tension in the tension members to permit the stented prosthesis to compress, self-expand, and ultimately release from the shaft assembly. In some embodiments, the tension in one or more tension members is adjusted with one or more actuation and release assemblies.

Abstract: The disclosure relates to transcatheter stented prosthesis delivery devices including transition elements that route, constrain, support and reduce damage to tension member wear as tension in the tension members is varied to adjust the compression of a stented prosthesis loaded onto the delivery device. Various disclosed tension elements include inserts, edge treatments and guides proximate a distal portion of the delivery device upon which the stented prosthesis is loaded. In some embodiments, the transition feature is positioned proximate a location where at least one tension member transitions from a first orientation that is not parallel to the distal portion to a second orientation that is generally parallel to the distal portion. Further embodiments disclose configurations and methods of selectively locking and unlocking a longitudinal and/or rotational position of the stent frame with respect to the distal portion of the delivery device.

Abstract: A system for replacing a heart valve of a patient. The system includes a delivery device and a prosthetic heart valve. The system is configured to be transitionable between a loaded state, a partially deployed state and a deployed state. In the loaded state, the prosthetic heart valve engages a coupling structure and is compressively retained within a primary capsule, which constrains the prosthetic heart valve in a compressed arrangement. In the partially deployed state, the prosthetic heart valve engages the coupling structure and is compressively retained within a secondary capsule, which constrains the prosthetic heart valve to a partially deployed arrangement. The partially deployed arrangement is less compressed than the compressed arrangement and less expanded than a deployed arrangement. In the deployed state, the primary and secondary capsules are retracted from over the prosthetic heart valve, which expands to the deployed arrangement and is released from the coupling structure.

Abstract: A transcatheter heart valve prosthesis configured in accordance herewith includes an expandable frame having a plurality of commissure posts extending therefrom, a radially expandable tubular component attached to the plurality of commissure posts, and a locking mechanism operably coupled to a wire. The wire is at least partially slideably disposed within a channel formed in a wall of the tubular component and the locking mechanism is configured to permit the wire to be advanced within the channel to thereby transition the tubular component into a deployed configuration that at least partially engages tissue at the native heart valve.

Abstract: A delivery device for percutaneously delivering a stented prosthetic heart valve includes a capsule assembly, a handle, and an outer stability shaft. The capsule assembly includes a capsule and a proximal shaft coupled to the capsule. The capsule includes an expanded configuration wherein the capsule has a first outer diameter, and a collapsed configuration wherein the capsule has a second outer diameter smaller than the first outer diameter. The outer stability shaft defines a lumen and is coupled to the handle and configured to receive the proximal shaft within the lumen of the outer stability shaft. The outer stability shaft has an inner diameter, wherein the first outer diameter of the capsule is greater than the inner diameter of the outer stability shaft and the second outer diameter of the capsule is smaller than the inner diameter of the outer stability shaft.
