Devices and methods for orthopedic support are disclosed. The device can have a first rigid section hingedly attached to a second rigid section. The device can be curved or rotated around obstructions along an access path to a target site. The device can be delivered to an intervertebral location in a patient.

The present invention provides a supporting member and a supporting member assembly including the same to be implanted into or between a subject's bones, and a template plug and a tamper corresponding to the supporting member. The supporting member comprises a main body; a first connecting portion and a second connecting portion formed on the upper and lower sides of the main body respectively and forming a dovetail joint with each other; and a guiding structure formed at a side of the main body and including guiding holes as well as a buffer groove for mating with an external template plug. The supporting members of the invention can be sequentially implanted and connected into a bone or between two connected bones, and improve the defect of the conventional one-size giant implants injuring the surrounding nerves.

This invention relates generally to spine surgery and, in particular, to a surgical implant for separating adjacent spinal vertebrae.

A vertebral insert may include a first linkage, a second linkage, and a third linkage. The first, second, and third linkages may at least partially defining a cavity. The insert may be movable between a collapsed configuration and an expanded configuration, and the movement of the first and second linkages with respect to one another may be configured to reciprocally move the insert between the collapsed and expanded configurations.

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.

An implantable prosthesis that includes a biased coiling member and a conforming coiling member. The biased coiling member may be biased to curve from a substantially linear configuration to a nonlinear configuration. The conforming coiling member may be engaged with and curved by the biased coiling member from the substantially linear configuration to the nonlinear configuration. The biased coiling member may define a longitudinal axis when in the substantially linear configuration. The biased coiling member and the conforming coiling member may move relative to each other along the longitudinal axis. The prosthesis may be implanted in a surgical procedure that minimizes incision sizes and may be considered less invasive than typical implant procedures, especially spinal implant procedures.

Described herein are devices and methods for fusion of adjacent vertebral bones of a subject using distractor platforms for the exposure and resection of at least a portion of the facet joint, such as in performance of a TLIF procedure. In one embodiment, the distractor platform contains at least a first receptacle and/or extension that are adapted to couple to the implanted screw/bone marker and the method includes advancing a first threaded segment of a first bone fastener assembly into the identified first pedicle of the first vertebral bone, wherein the first bone fastener assembly further comprises a second segment that is adapted to couple with a distraction platform adapted to concurrently attach onto at least one tissue retention blade and is adapted to retain the tissue retention blade in the displaced position.

A vertebral insert may include a first linkage, a second linkage, and a third linkage. The first, second, and third linkages may at least partially defining a cavity. The insert may be movable between a collapsed configuration and an expanded configuration, and the movement of the first and second linkages with respect to one another may be configured to reciprocally move the insert between the collapsed and expanded configurations.

Enzymatic and non-enzymatic detectors and associated membrane apparatus, and methods of use, such as within a fully implantable sensor apparatus. In one embodiment, detector performance is controlled through selective use of membrane configurations and enzyme region shapes, which enable accurate detection of blood glucose level within the solid tissue of the living host for extended periods of time. Isolation between the host's tissue and the underlying enzymes and reaction byproducts used in the detectors is also advantageously maintained in one embodiment via use of a non-enzyme containing permeable membrane formed of e.g., a biocompatible crosslinked protein-based material. Control of response range and/or rate in some embodiments also permits customization of sensor elements. In one variant, heterogeneous detector elements are used to, e.g., accommodate a wider range of blood glucose concentration within the host. Methods of manufacturing the membranes and detectors, including methods to increase reliability, are also disclosed.
