摘要:
An orthopedic implant device (100, 200, 300, 301, 320, 340, 400, 500, 600, 700', 720, 740, 760, 770, 800, 900, 1000, 1100, 1200, 1300, 1400, 1500, 1600, 1700, 1800) is non-rigid, i.e., flexible and/or malleable, in a first form for insertion into a desired in vivo site, and then transformable into a rigid, or hardened, form for providing a load-bearing function or providing other structural and/or mechanical function after implantation. The device includes a biocompatible sheath (110) and a curable material (120) sealed within the sheath (110). The curable material (120) is provided in a first form that provides flexibility to the device and is structured to rigidize in a second form after insertion to an in vivo location at least one minute after application of a cure-initiating energy to the material (120) prior to insertion. Related methods and kits are also provided.

An acetabular cup prosthesis comprising a shell component, a liner component located within the shell component and a filling means located in a space between the shell component and the liner component.
摘要:
An instrument for cutting an extension, such as a catheter or biomaterial, coupled to a prosthesis, such as a prosthesis located in an intervertebral disc space, that includes at least one axial member having a distal opening and at least one cutting device, such as for example a wire or blade, coupled to the at least one axial member that is capable of moving across at least a portion of the distal opening when a force is applied to the at least one cutting wire. A method for cutting a catheter is also disclosed. The removal instrument may be inserted into an introduction lumen. A force is applied to the at least one cutting device after the catheter is in the distal opening.
摘要:
Resilient surgical meshes that, in some aspects, can be compressed or otherwise configured, for minimally invasive delivery in the intervertebral discs are provided. According to one or more embodiments, the surgical mesh can be robust, fatigue resistant, stable and capable of withstanding the dynamic environment generic to intervertebral discs.

Methods and devices are provided for repairing or replacing damaged, injured, diseased, or otherwise unhealthy posterior elements, such as the facet joints, the lamina, the posterior ligaments, and/or other features of a patient’s spinal column. In one exemplary embodiment, and implant is provided having an anterior portion that is adapted to be positioned between adjacent vertebrae and a posterior portion that is adapted to be positioned around a spinal cord and to couple to a posterior surface of at least one adjacent vertebra. In use, the implant can allow the adjacent vertebrae to move relative to one another, thereby restoring normal function to the vertebrae.
摘要:
Systems for minimally invasive disc augmentation include an anulus augmentation component (552) and a nucleus augmentation component (554). Both are suited for minimally invasive deployment. The nucleus augmentation component (554) restores disc height and/or replaces missing nucleus pulposus. The anulus augmentation (552) component shields weakened regions of the anulus fibrosis and/or resists escape of natural nucleus pulposus and/or the nucleus augmentation component (554). Methods and deployment devices are also disclosed.
摘要:
An intervertebral disc is expanded and injected by forming and dilating an opening in the disc annulus and introducing an inflatable member into the disc nucleus pulposus. The inflatable member location within the nucleus pulposus is verified and the inflatable member is gradually inflated for augmenting a space in the nucleus pulposus. The internal pressure and expansion of the inflatable member are monitored. The inflatable member is subsequently deflated and a biomaterial is injected into the augmented space.

Devices for insertion within a facet joint formed between adjacent vertebral members. The devices include an intermediate section (30) sized to fit within the facet joint. The devices may also include one or more mounting sections (20) that extend across the face of one or both vertebral members to receive a fastener (40) for mounting the device. Methods of using the devices may- include positioning the intermediate section within the facet joint and connecting the device to one or both vertebral members .
摘要:
By providing an elastic form stable material which is capable of being delivered directly to a specific desired location within a living creature and providing increased strength and rigidity to the injected location, disorders of the intervertebral disc of a living creature are able to be effectively treated. Treatment of defects or voids in soft tissue is achieved with a variation of the subject material specific to each application. In the preferred method, the elastic form stable material is injected directly into the affected area, thereby achieving the desired result.
摘要:
An implant (10) for use with the opposing facets of two adjacent vertebrae includes a facet bearing body (20) having a cavity (23) for receiving a filler material (29), and at least one fixation wing (22, 24) for securing the facet bearing body (20) to at least one of the two vertebrae, wherein the facet bearing body (20) is positionable between the opposing facets and the at least one fixation wing (22, 24) is fixable to at least one of the two vertebrae. The filler material (29) may be an in situ curable polymer such as bone cement, a polyurethane or an elastomer. To stabilize the adjacent vertebrae, the facet bearing body (20) is inserted between the opposing facets of the adjacent vertebrae. The at least one fixation wing (22, 24) is fixed to at least one of the two adjacent vertebrae. The filler material (29) is injected into the cavity (23) and allowed to harden.
