Systems and related methods for changing the angle of a bone of a subject is provided by the present disclosure. The system may include a non-invasively adjustable implant configured to be placed inside a cavity within the bone. The non-invasively adjustable implant may couple to a first portion of bone and a second portion of bone that is separated or separable from the first portion of bone, such that non-invasive elongation of the adjustable implant causes movement of the first portion of bone and the second portion of bone apart angularly. The system may include an anchor configured to couple the non-invasively adjustable implant to bone. The non-invasively adjustable implant may include an anchor hole configured to receive the anchor therein.

The present technology is generally directed to implantable medical devices and associated methods. For example, a system configured in accordance with embodiments of the present technology can include a body implantable into a patient and configured to undergo a shape change, the body having a conductive path with variable conductivity in portions thereof for selective and/ or preferential heating. The body can be coupled with an energy source that can delivery energy to the body and/or conductive path, to promote the shape change in the body.

An apparatus includes a plurality of beads and a linking assembly joining the beads together. The beads and the linking assembly are arranged in an annular arrangement and sized to form a loop around an anatomical structure in a patient. The loop may move between a contracted and expanded configuration. The loop is magnetically biased toward the contracted configuration by a magnetic bias of the beads. The beads each include a housing defining a magnet chamber and a magnet assembly disposed within the magnet chamber. The magnet assembly includes at least one annular magnet and an encasement surrounding the at least one annular magnet to provide a seal between the at least one annular magnet and the magnet chamber.

An apparatus includes a plurality of beads each defining a first opening and a second opening, a linking assembly, and a 3D printed magnetic element housed within a first bead of the plurality of beads. The linking assembly extends through the first opening and the second opening of each bead such that the beads and the linking assembly may be arranged in an annular arrangement to form a loop around an anatomical structure in a patient. The loop moves between a contracted configuration and an expanded configuration and is magnetically biased toward the contracted configuration. The 3D printed magnetic element is housed within a first bead of the plurality of beads. The 3D printed magnetic element include a composite of magnetic granules combined to generate a magnetic field. The magnetic field is generated by the 3D printed element and is configured to contribute toward the magnetic bias.

An apparatus includes at least one link and a plurality of beads. The plurality of beads are joined using the at least one link and configured to be arranged in an annular arrangement. Each bead includes at least one magnet. The annular arrangement is sized and configured to form a loop around an anatomical structure in a patient. Adjacent beads are magnetically attracted together at a plurality of magnetic interfaces that include first and second magnetic interfaces. The first magnetic interface has a first magnetic field strength. The second magnetic interface has a second magnetic field strength that is less than the first magnetic field strength so that the beads forming the second interface are configured to separate prior to the beads forming the first interface when the loop moves from the contracted configuration to the expanded configuration, thereby providing uniform radial expansion of the loop.

An apparatus includes a plurality of beads. Each bead includes a housing and a magnet positioned within the housing. The apparatus also includes a plurality of interconnection elements. Each interconnection element movably joins together a corresponding pair of beads. The plurality of beads and the plurality of interconnection elements are sized and configured to form an expandable loop around an anatomical structure in a patient. The apparatus further includes a decoupling element. The decoupling element is positioned along the loop and is configured to selectively release a first portion of the loop from a second portion of the loop in response to application of a threshold force to the at least one decoupling element in a circumferential direction relative to the loop.

A method of manufacturing a bead assembly for a sphincter augmentation device includes initiating 3D printing of a unibody housing such that the unibody housing defines a first opening, a chamber, and a magnet chamber. The method further includes pausing the 3D printing process, inserting a magnet within the magnetic chamber, and then resuming 3D printing of the unibody housing to form a hermetic seal between the magnet chamber and an external surface of the unibody housing.

An apparatus includes a plurality of beads and a linking assembly joining the beads together. The beads include a first bead having a first external contact surface, and a second bead having a second external contact surface. A magnet is contained within the housing. The beads and the linking assembly are arranged in an annular arrangement and sized to form a loop around an anatomical structure in a patient. The loop may move between a contracted and expanded configuration. The loop is magnetically biased toward the contracted configuration by a magnetic bias of the beads. The first external contact surface and the second external contact surface engage each other as the loop transitions into the contracted configuration to drive the first bead and the second bead into a predetermined orientation relative to each other about the linking assembly in the contracted configuration.

An apparatus includes a plurality of beads, a linking assembly joining the beads together, and an integrated adjustment assembly. The beads and the linking assembly are arranged in an annular arrangement and sized to form a loop around an anatomical structure in a patient. The loop may move between a contracted and expanded configuration. The loop is magnetically biased toward the contracted configuration by a magnetic bias of the beads. The integrated adjustment assembly is integrated with the plurality of beads of the linking assembly. The integrated adjustment assembly is operable to selectively adjust either the maximum radius or the minimum radius of the beads and the linking assembly while remaining integrated with the plurality of beads or the linking assembly.

An apparatus includes at least one link and a plurality of beads. The plurality of beads is joined using the at least one link. The housing includes a magnet chamber. The magnet is configured to emit a magnetic field to magnetically bias the loop toward the contracted configuration. The magnet is sized and configured to move within the magnet chamber. A consistent angular orientation of adjacent housings is determined by at least one of the following adjustment parameters: a magnitude of the magnetic fields of adjacent magnets disposed in the adjacent housings by altering a distance between the adjacent housings, a directionality of the adjacent magnets within adjacent magnet chambers by allowing for twist of the magnet within the magnet chamber, or a freedom of the adjacent magnets to move within the adjacent magnet chambers by allowing the magnets to move laterally within the respective magnet chambers.
