    Abstract: An implantable prosthetic device can include a frame that is radially expandable and compressible between a radially compressed configuration and a radially expanded configuration. The frame can include a plurality of struts, each strut comprising a first portion and a second portion separated by a deflection point. Each strut can be curved helically with respect to a first, longitudinal axis of the frame. The first portion of each strut can be curved in a first direction with respect to a first line parallel to a second axis that is perpendicular to the first, longitudinal axis of the frame, and the second portion of each strut can be curved in a second direction with respect to a second line parallel to the second axis.

  • Publication number: 20220280287
    Abstract: An assembly can comprise a prosthetic valve comprising a radially expandable and compressible frame and a rotatable screw connected to the frame, where the screw comprises a screw head having an annular bore with internal threads, and where the screw is rotatable to radially expand the frame. The assembly further comprises a delivery apparatus releasably coupled to the screw, the delivery apparatus comprising a first shaft and a first head disposed at an end of the first shaft, the first head comprising external threads configured to engage with the internal threads of the screw head, and a second shaft that is coaxial with and surrounds the first shaft, the second shaft comprising a second head disposed at an end of the second shaft. The second head is configured to releasably engage with an exterior surface of the screw head and rotate the screw.

  • Publication number: 20220257367
    Abstract: An implantable prosthetic valve can include a frame movable between a radially compressed and a radially expanded configuration. The frame can include a first strut having a first locking feature disposed on a radially facing inner surface of the strut and a second strut having a second locking feature disposed on a radially facing outer surface of the strut. The first and second locking features can engage each other so as to allow pivoting of the first and second struts relative to one another in a first direction upon radial expansion of the frame and resist pivoting of the first and second struts relative to one another in a second direction to resist radial compression of the frame.

  • Publication number: 20220233310
    Abstract: Expandable sheaths are disclosed herein. In some embodiments, a braided layer is positioned radially outward from a first polymeric layer. The braided layer includes a plurality of filaments braided together. A second polymeric layer is positioned radially outward of the braided layer, such that the braided layer is encapsulated between the first and second polymeric layers. In some embodiments, a braided layer is adhered to a sealing layer that is impermeable to blood flow. Methods of making and using the devices disclosed herein are also disclosed, as are crimping devices that may be used in methods of making the devices disclosed herein.

  • Publication number: 20220160497
    Abstract: An implantable prosthetic device comprises a frame comprising a first set of first struts and a second set of second struts. The first struts are pivotably connected to each other at a plurality of distal and proximal apices at distal and proximal ends of the frame. The second struts are pivotably connected to each other at a plurality of distal and proximal apices at the distal and proximal ends of the frame. The first struts have a first thickness, and the second struts have a second thickness, wherein the first thickness is greater than the second thickness. One or more actuators are coupled only to one or more corresponding pairs of a distal apex and a proximal apex formed by the first struts, wherein the one or more actuators are configured to apply axially directed forces to the frame to radially expand the frame.

  • Patent number: 11291540
    Abstract: Docking stations for transcatheter valves are described. The docking stations can include an expandable frame, at least one sealing portion, and a valve seat. The expandable frame can be configured to conform to an interior shape of a portion of the circulatory system when expanded inside the circulatory system. The sealing portion can be configured to contact an interior surface of the circulatory system to create a seal. The valve seat can be connected to the expandable frame and can be configured to support an expandable transcatheter valve. The docking stations are adaptable to different anatomies/locations to allow implantation of a transcatheter valve in a variety of anatomies/locations.
