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.

Abstract: Heart valve prosthesis are disclosed that include a frame or support structure having an inflow portion, a valve-retaining tubular or central portion and a pair of support arms. The inflow portion radially extends from a first end of the valve-retaining tubular portion and the pair of support arms are circumferentially spaced apart and radially extend from an opposing second end of the valve-retaining tubular portion.

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: 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: Aspects of the disclosure relate to devices and methods for preparing an existing, implanted prosthetic aortic valve for subsequent prosthetic aortic valve implantation. To prepare the existing valve, a valve preparation device is delivered to the valve and valve leaflets are severed either via mechanical cutting or electrodes so that the leaflets cannot obstruct a blood flow path once a prosthetic valve is subsequently implanted within the valve. Similarly, in alternate embodiments, devices and methods of the disclosure can be used for preparing a native aortic valve for delivery and implantation of a prosthetic valve.

Abstract: Prosthetic heart valve devices, heart valve replacement systems and associated methods for percutaneous heart valve replacement are disclosed herein. A transcatheter heart valve prosthesis configured in accordance herewith includes an expandable frame having a plurality of commissure posts extending therefrom, a radially expandable inflow member 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 inflow member and the locking mechanism is configured to permit the wire to be advanced within the channel to thereby transition the inflow member into a deployed configuration that at least partially engages tissue at the native heart valve.
