    摘要： An anti-adhesion device in the form of a fillable balloon having a wall structure permits suturing or other attachment of the balloon to surrounding tissues. The balloon may be filled with a gas, liquid, or gel, and may be constructed of a resorbable material. The balloon may contain one or more growth factors and one or more antibodies to the growth factors may also be provided. Cytokines may be incorporated into the wall structure. The associated surgical procedure includes suturing or otherwise attaching the balloon between healing tissues and surrounding tissues. The healing tissues may include the vagina and the surrounding tissues include the small intestines, the great vessels and the spine following anterior spinal surgery, or any other appropriate location(s). The balloon may be placed immediately after an open surgical procedure or, alternatively, through smaller incisions as part of a minimally invasive procedure. Thus, the balloon may be filled prior to introduction or following placement. In the preferred embodiment the balloon ruptures and resorbs after the surgically treated tissues are partly or completely healed.

    摘要： Check reins in the form of elongated members are used to limit the extreme range of motion which would otherwise be permitted by some ADR designs. The check reins serve two main purposes. First, they retain disc spacers, if present. Additionally, the wedge shape of ADRs and the removal of the Anterior Longitudinal Ligament (ALL) and a portion of the Annulus Fibrosus (AF) to insert the ADR from an anterior approach, favor anterior extrusion of disc spacers. In preferred embodiments the check reins are therefore limited to the anterior portion of the periphery of the ADR. Second, check reins serve to prevent excessive spinal motion. Again, although they may be helpful in other locations, anterior check reins help restore the motion limiting functions of the ALL and AF that were removed in anterior approaches to the spine.

    摘要： A method for performing kyphoplasty is disclosed. A catheter having a balloon-like component is located at its distal end, is inserted into a fractured vertebra. A substance such as PMMA to fill the balloon and stabilize the fracture is injected through the catheter. The balloon is held in place until the material begins to set.

    摘要： Surgical implants are configured for placement posteriorly to a spinal canal between vertebral bodies to distract the spine and enlarge the spinal canal. In the preferred embodiments the device permits spinal flexion while limiting spinal extension, thereby providing an effective treatment for treating spinal stenosis without the need for laminectomy. The invention may be used in the cervical, thoracic, or lumbar spine. Numerous embodiments are disclosed, including elongated, length-adjustable components coupled to adjacent vertebral bodies using pedicle screws. The preferred embodiments, however, teach a device configured for placement between adjacent vertebral bodies and adapted to fuse to the lamina, facet, spinous process or other posterior elements of a single vertebra. Various mechanisms, including shape, porosity, tethers, and bone-growth promoting substances may be used to enhance fusion. The tether may be a wire, cable, suture, or other single or multi-filament member. Preferably, the device forms a pseudo-joint in conjunction with the non-fused vertebra. Alternatively, the device could be fused to the caudal vertebra or both the cranial and caudal vertebrae.
