  • Publication number: 20240050105
    Abstract: Systems and methods for providing access to within a vertebral body. A stylet is removably disposed within a reamer, and the reamer is removably disposed within a working cannula. A tip of the stylet is positioned distal to a reamer head with a stylet hub being positioned proximal to a reamer hub. The reamer hub may include indicia configured to be aligned with the stylet hub to indicate a distance by which the tip is positioned beyond a distal end of the reamer. Complementary coupling features on the reamer hub and the stylet hub are configured to facilitate the workflow and provide mechanical advantage during removal of the stylet from the reamer. The system may include a spacer device configured to be positioned between the reamer hub and the stylet hub. The spacer device may be coupled to a stylet shaft of the stylet.

  • Publication number: 20240050139
    Abstract: An expandable implant for bone restoration. The implant includes a first end element and a second end element. A plate is expandable in a first direction, and a blade expandable in a second direction. A first interconnecting element extends between the plate and at least one of the first and second end elements. A second interconnecting element extends between the blade and at least one of the first and second end elements. When the implant is in a collapsed position, a length of the blade is substantially parallel to the longitudinal axis, and when the blade is in an expanded position, the length of the blade is non-parallel to the longitudinal axis. The blade may include a length extending from a base to a tip, and the tip of the blade is further from the longitudinal axis than the plate when the implant is in the expanded position.

  • Patent number: 11752004
    Abstract: A system configured to increase height of a vertebral body. An implant includes plates each defining a bearing surface configured to be moved away from one another to expand the implant within the vertebral body. Supports are each coupled to one of the plates and include a reduced thickness portion defining a material web configured to plastically deform during expansion of the implant. The system includes an implant carrier with which an end element of the implant is removably coupled, and a rod configured to be translated relative to the implant carrier to cause expansion of the implant. An opposed portion may be coupled to the supports and configured to receive a longitudinal force to be moved relative to the end element. Second supports may be each coupled to the end element and one of the plates. Each of the second supports may plastically deform during expansion of the implant.

  • Publication number: 20230130342
    Abstract: An implant for restoring height of a vertebral body. The implant includes upper and lower plates configured to be moved away from one another in the craniocaudal direction. A first support and a second support are arranged to crisscross in a proximal-to-distal direction to facilitate increased expansion of the implant, and a third support and a fourth support may be arranged to crisscross in the proximal-to-distal direction. Certain supports may be laterally spaced from one another to define a void space for receiving a retaining element. An upper support fork may include a first pair of supports arranged in a V-shaped configuration and converge at an apex that is coupled to an underside of the upper plate. A lower support fork may include a second pair of supports arranged in a V-shaped configuration and converge at another apex that is coupled to an upper side of the lower plate.

  • Patent number: 11540926
    Abstract: An implant for restoring height of a vertebral body. The implant includes upper and lower plates configured to be moved away from one another in the craniocaudal direction for the implant to be deployed. Supports are coupled to the upper plate and a distal end portion, and arranged in a crisscross configuration in the proximal-to-distal direction in each of an insertion configuration and a deployed configuration. The crisscross configuration facilitates increased expansion of the implant. The supports may be laterally spaced from one another to define a void space for receiving retaining element, and inner and outer arcuate surfaces may provide a generally cylindrical profile to the implant. One of the supports may be a support fork arranged in a V-shaped configuration. A length of the supports may be approximately 50-90% of a length of the upper and lower plates. The implant may be formed through additive manufacturing.

  • Publication number: 20220240987
    Abstract: Systems and methods for treating a vertebral body. An intravertebral implant includes an anterior end element and a plate comprising a planar bearing surface. The plate may be exactly two plates movable in only a cranio-caudal expansion plane. A pedicle fixation is coupled to the intravertebral implant and includes a hollow sleeve. The pedicle fixation is configured to be secured to the pedicle to control an insertion depth of the intravertebral implant within the vertebral body. A central traction member is movably disposed within the hollow sleeve of the pedicle fixation to deploy the planar bearing surface(s). The central traction member may be rotatable within the hollow sleeve. An expansion instrument may move the central traction member relative to the pedicle fixation. The intravertebral implant may be locked relative to the pedicle fixation in six degrees of freedom.

  • Patent number: 11389181
    Abstract: A steerable system and methods for accessing bone. A control mechanism includes a handle configured to be detachably secured to a trocar. The handle includes a drive shaft coupled to a sliding shaft such that relative rotation is prevented and relative translation is permitted. A rod having a preformed bend is removably disposed within the cannula. The rod is prevented from rotating relative to the drive shaft such that a deflection plane of the preformed bend is predefined relative to each of the sliding shaft, the handle, and the trocar when the handle is coupled to the trocar. Rotating a sliding ring of the handle translates the drive shaft to advance the rod beyond the trocar such that the preformed bend extends laterally out of the trocar in the deflection plane. The rod may be removed from the cannula, and material may be injected through the cannula.

  • Patent number: 11191575
    Abstract: Systems and methods for augmenting a vertebral body may include an optional access cannula, introducer device, and a stylet having a stylet shaft. The access cannula includes a hub portion and a cannula shaft extending from the cannula hub. The cannula shaft includes a distal end positionable within the vertebral body that defines a lumen along a longitudinal axis. The introducer device may be a telescoping or pivoting introducer device that is removably coupled to the hub portion of the access cannula. The introducer device controls the movement of the flexible distal portion of the stylet shaft and the flexible sheath from within the introducer device through the access cannula to within a target site in the vertebral body, wherein the flexible distal portion is moved from the constrained to the unconstrained state to displace cancellous bone within the target site.

  • Publication number: 20200187992
    Abstract: Methods of deploying an intravertebral implant having an expandable anterior part, a posterior part coupled to the expandable anterior part, and a pedicle fixation element. The expandable anterior part is positioned within the vertebral body, and the posterior part may be positioned within the vertebral body. The pedicle fixation element is anchored to the vertebral body. The expandable anterior part is moved relative to the pedicle fixation element, for example, in two degrees of freedom. Movement in a first of the two degrees of freedom is independent from movement in a second of the two degrees of freedom. The expandable anterior part may be translated without being rotated along a main axis of the pedicle fixation element. Filling material may be injected through the posterior part. Rotational movements of the expandable anterior part relative to the pedicle fixation element may be locked.
