Abstract: A basilica system for use in replacement heart valve implant procedures may include a first catheter including a side port disposed proximal of a distal tip, a conductive guidewire slidably disposed within the first catheter and configured to be advanced out the side port proximate a leaflet of a replacement heart valve implant disposed within a native heart valve of a patient, a second catheter including a lumen extending to a distal end of the second catheter, and a snare shaft slidably disposed within the second catheter, the snare shaft including a wire loop configured to grasp the conductive guidewire. The basilica system may include a delivery catheter. The first and second catheters may be disposed within the delivery catheter. The conductive guidewire may be configured to be electrically coupled to a source of RF energy. The conductive guidewire may be configured to puncture the leaflet.

Abstract: An implantable medical device is adapted to be implanted at an implantation site such as a native cardiac valve annulus. The implantable medical device includes an expandable frame that is adapted to expand from a collapsed configuration for delivery to an expanded configuration for deployment, one or more valve cusps secured relative to the expandable frame, an inner skirt surrounding a portion of the expandable frame, and an outer skirt surrounding a portion of the expandable frame, the outer skirt attached to the expandable frame via one or more sutures that axially secure the outer skirt relative to the expandable frame yet allow the outer skirt to move radially relative to the expandable frame. The outer skirt may move radially outwards in response to fluid pressure, thereby improving fluid sealing relative to the native cardiac valve annulus.

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 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.

Abstract: A replacement heart valve implant includes an expandable framework including a commissure post and defining a central lumen, and a valve leaflet disposed within the central lumen, the valve leaflet including a mounting tab secured to the expandable framework at the commissure post. The commissure post is configured to hold the mounting tab in compression. A tool for assembling a replacement heart valve implant includes a tool body comprising first and second body portions, first and second handle portions extending from the body portions, and first and second post engagement arms extending from the body portions. Translation of the first handle portion toward the second handle portion translates the first post engagement arm away from the second post engagement arm.

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.
