Abstract: Various multiaxial receivers for receiving at least one tether are disclosed. A multiaxial receiver may include a body having a U-shaped cavity configured to receive a longitudinal rod therein and a lower cavity configured to couple to a pedicle screw. The body may include a first aperture extending through a side surface of the body and defining a first passageway configured to permit a tether to pass therethrough in the horizontal direction. In some embodiments, the body may include a second aperture extending through the side surface of the body and defining a second passageway configured to permit the tether to pass therethrough in the horizontal direction. A set screw may be configured to be rotated from an open position in which the tether is permitted to pass through the first passageway and optionally through the second passageway to a closed position in which the tether is immobilized.

Abstract: A multiaxial receiver may include a body having a U-shaped cavity configured to receive a longitudinal rod therein and a lower cavity configured to couple to a pedicle screw. The multiaxial receiver may include a first passageway configured to permit a tether to pass therethrough in the vertical direction. In some embodiments, the multiaxial receiver may also include a second passageway configured to permit a tether to pass therethrough in the horizontal direction. An immobilization assembly including a set screw and a wedge may immobilize the tether. The immobilization assembly may be configured to be rotated from an open position in which the tether is permitted to pass through the first passageway to a closed position in which the tether is immobilized within the first passageway or second passageway by pining the tether against a bearing surface of the first passageway.

Abstract: A stented valve having at least one leaflet made of pericardium or other material having a relatively thin profile at the annulus. The leaflets are attached via chords to a stent frame, where the chords are positioned to mimic the native valve anatomy and functionality. In particular, the valves of one exemplary embodiment of the invention are sized to replace a mitral valve and therefore the chords are arranged to prevent prolapse of the leaflets into the atrium. The stented valve has a relatively short height at its annulus due to the positioning of the chords. In addition, the stented valve is capable of being crimped to a small enough size that it can be delivered to the implantation site via transcatheter delivery systems and methods.

Abstract: An annuloplasty ring including a sheath, an arcuate stiffening element, and a tensioning member. The stiffening element is disposed within the sheath and defines discrete, first and second ends separated by a lateral spacing. The tensioning member extends between the stiffening element ends. The tensioning member is characterized as being more flexible than the stiffening element and is configured to provide a taut state in which the tensioning member is substantially non-extensible and impedes expansion of the lateral spacing. With this configuration, the stiffening element serves to remodel the valve annulus to a desired shape, while the tensioning member exhibits sufficient flexibility to allow for natural movement of the valve annulus while limiting (in the taut state) the extent of annular dilatation (e.g., overt lateral separation of the first and second ends of the stiffening member) due to in vivo forces.
