Abstract: An implantable medical device adapted to be implanted at an implantation site may be capable of being implanted in more than one rotational orientation at the implantation site. The implantable medical device includes an expandable body that is adapted to expand from a collapsed configuration for delivery to an expanded configuration for deployment, and a radiopaque indicator that is disposed relative to the expandable body. The radiopaque indicator is adapted to be have a first appearance if viewed in a first rotational orientation and a second, different appearance if viewed in a second rotational orientation that is different from the first rotational orientation. As an example, the implantable medical device may be a catheter-delivered replacement aortic valve.

Abstract: A device for radially compressing a stent may include a housing including a central opening and a first iris positioned adjacent the housing. The first iris includes a first circumferential ring and a first plurality of arms extending radially inward from the first circumferential ring to define a first central opening. The device may include a second iris axially offset from the first iris and including a second circumferential ring and a second plurality of arms extending radially inward from the second circumferential ring to define a second central opening. Rotation of the circumferential ring(s) relative to the housing changes a size of their respective central opening(s). The plurality of arms may shift between a first configuration and a second configuration via rotation of the circumferential ring(s) relative to the housing.

Abstract: A replacement heart valve implant may include an expandable framework having a plurality of frame struts defining a lattice structure, each frame strut having a thickness in a radial direction from a central longitudinal axis; and a plurality of valve leaflets coupled to the expandable framework. The plurality of frame struts defines a lower crown proximate an inflow end of the lattice structure and upper crown proximate an outflow end of the lattice structure and a plurality of stabilization arches extending downstream from the outflow end of the lattice structure. The lattice structure includes a first circumferential row of x-connectors upstream of the upper crown and a second circumferential row of x-connectors downstream of the lower crown. The thickness of at least some frame struts connecting the first and second circumferential rows of x-connectors is less than the thickness of other frame struts of the plurality of frame struts.

Abstract: Embodiments herein relate to methods of attaching leaflets to a valve frame and valves made using the same. In an embodiment, a method of making an implantable prosthetic valve is included. The method can include compressing at least a portion of valve leaflet tabs, inserting the compressed valve leaflet tabs into commissural slots of a valve frame, and expanding the compressed valve leaflet tabs. Other embodiments are also included herein.

Abstract: A replacement heart valve system may include a replacement heart valve implant including an expandable framework configured to shift from a radially collapsed configuration to a radially expanded configuration and a plurality of valve leaflets attached to the expandable framework at a plurality of commissure posts, and an implant delivery system including a handle and an elongate shaft assembly, the elongate shaft assembly including a tubular member fixedly attached to the handle, and an implant holding portion configured to constrain the expandable framework in the radially collapsed configuration. The elongate shaft assembly includes an anti-migration element configured to shift between a delivery configuration and an open configuration. The anti-migration element is configured to prevent proximal movement of the expandable framework relative to the tubular member in the open configuration.

Abstract: An alignment tool includes a body and a plurality of securement arms extending from the body, each of the plurality of securement arms adapted to releasably secure the alignment tool relative to a loader. The alignment tool includes a plurality of alignment arms extending from the body, each of the plurality of alignment arms including a first end having an alignment slot and an opposing second end including a handle portion, the plurality of alignment arms movable between a closed configuration defining a minimum distance between the first end of each of the plurality of alignment arms and an open configuration defining a maximum distance between the first end of each of the plurality of alignment arms. The plurality of alignment arms are biased into the closed configuration.

Abstract: An outer sheath for use with a medical device delivery system includes a tubular member defined by a circumferential wall and having a distal end, a proximal end, and a lumen extending therebetween along a central longitudinal axis of the tubular member. The tubular has a distal region that is configured to shift between an enlarged configuration and a collapsed configuration. The distal region also includes at least one compression element configured to automatically radially collapse the distal region when the lumen of the distal region is empty.
