  • Publication number: 20060089718
    Abstract: Systems and method in accordance with embodiments of the present invention can includes an implant having a spacer with an expandable portion. An insert can be positioned within a groove of the spacer to distract the expandable portion away from the main portion of the spacer. The expandable portion can optionally include a grip that can at least partially deform to conform to a contour of a spinous process to provide a frictional grip to prevent the implant from shifting position. Implants in accordance with the present invention can also include a binder that can be arranged around the adjacent spinous processes to limit flexion movement.

  • Publication number: 20060069439
    Abstract: The present disclosure is directed to an implant that can be placed between two vertebrae using a lateral, anterior or posterior insertion method. The implant is characterized by having a first endplate and a second endplate, both endplates having inner surfaces that oppose each other when anchored into opposing vertebral bodies. The inner surfaces give rise to two articulating elements, each articulating element including two compatible units that mate and allow motion of the spine, including flexion, extension, lateral motion and rotational movement.

  • Publication number: 20060064165
    Abstract: Systems in accordance with embodiments of the present invention can include an implant comprising a spacer for defining a minimum space between adjacent spinous processes, a distraction guide for piercing and distracting an interspinous ligament during implantation, and a binder for limiting or preventing flexion motion of the targeted motion segment. The binder can be secured to a brace associated with the implant during implantation by a capture device. In one embodiment, the capture device includes a fixed piece extending from the brace and a slidable piece associated with the fixed piece. A fastener can be rotated to pinch the binder between the slidable piece and a wall of the brace, securing the binder. A physician need not know the length of the binder prior to implantation, reducing the time required to perform a procedure.

  • Publication number: 20060036258
    Abstract: Systems and methods in accordance with the present invention can be applied to distract adjacent interspinous processes and measure a distraction height, so that an appropriately sized implant can be positioned between interspinous processes to relieve pain associated with at least one of the spinal column and associated structures. A system in accordance with one embodiment can include a sizing distractor having distraction prongs extending from opposing jaws, the opposing jaws can taper laterally toward the distraction prongs to assist in positioning the distraction prongs between obstructive structures related to the spine.

  • Publication number: 20050283237
    Abstract: An intervertebral disk implant is described that has flanges designed to maximize mechanical strength, and at the same time is designed to provide for spatial complementarity of the flanges. In this regard, multiple devices can be implanted between consecutive intervertebral spaces, since the spatially complementary configuration of the flanges allow more than one device to be securely and conveniently anchored on the body of the same vertebral body.

  • Publication number: 20050283243
    Abstract: The present invention is directed to an implant that can be placed between two adjacent vertebral bodies using a lateral insertion method. The implant is characterized as having a first end plate and a second end plate which a crossbar spacer therebetween. The crossbar spacer preferably fits within a channel on the inner surfaces of the first end plate and the second end plate, whereby the spacer allows pivots, twisting and/or rotational movement of the spine. The first end plate and the second end plate include a keel extending therefrom, whereby the keel traverses longitudinally between a first lateral side and a second opposed lateral side and is substantially perpendicular to the sagittal plane of the patient's spine.

  • Publication number: 20050283242
    Abstract: An intervertebral disk implant is adapted to be placed between two vertebrae using a lateral insertion method. The implant is characterized by features including a first end plate having a first socket and a second end plate having a second socket with a spacer that is at least partially received in the first socket and the second socket. The implant includes at least one keel that is adapted to be inserted laterally into a vertebral body of the spine. The spacer allows for pivotal or rotational motion and also for twisting motion of the spine once the implant is inserted between vertebrae of a patient.

  • Publication number: 20050245937
    Abstract: The present invention is directed to a device that is implanted between the spinous processes of adjacent vertebrae of the spine and used for relieving pain associated with the vertebrae and surrounding tissues and structures by maintaining and/or adding distraction between adjacent vertebrae. The present invention includes a tissue expander adapted to move from a first insertion position, for ease of implantation between spinous processes, to a second retention position that prevents displacement of the implant.

  • Publication number: 20050240182
    Abstract: A supplemental spine fixation device and method is used in association with a primary spine fixation device. The supplemental spine fixation device includes a guide and spacer for distracting apart adjacent spinous processes and the device has hook members which hook about the first and second spinous processes. With the spinous processes distracted and the hook members about the spinous processes, the hook members can be rigidly secured to a hub in order to rigidly affix the spinous processes about the spacer. The rigidity between the spinous processes assures that the vertebral bodies will be held rigidly in place in order to promote bone growth and fusion. Further additional freedom of movement between the spacer and hub is accomplished with the spacer being pivotably mounted relative to the hub. The hooks have a tissue distracting lead-in guide for allowing the hooks to be easily urged between spinous processes.

  • Publication number: 20050216087
    Abstract: The present invention is directed to a device that can be placed between two adjacent vertebrae, and that is used to repair an injury or defect in the anulus of the intervertebral disk. The implant is characterized by having a flexible structure anchored to the vertebral bone, the flexible structure connected with a patch held in place over the injury or defect. The flexible structure has a hollow interior space which can sustain inside it a hydrogel cushion. The hydrogel cushion acts as a shock absorber for the spine, maintains height of the intervertebral disk space, and prevents further disk herniation due to the narrowing of the intervertebral disk space.

  • Publication number: 20050209603
    Abstract: A method for the implantation of a device made of bioresorbable materials between interspinous processes is described. The implant has a spacer that can be placed between adjacent spinous processes to limit the movement of the vertebrae. Once inserted between interspinous processes, the implant acts to limit extension (backward bending) of the spine without inhibiting the flexion (forward bending) of the spinal column. The device is used as an adjunct to remediation of an intervertebral disk.
