  Modular articulating and fusion spinal disc implant systemUSPTO Application #: 20070093900Title: Modular articulating and fusion spinal disc implant system Abstract: The present invention provides an intervertebral implant for replacing intervertebral disc material and controlling relative motion between adjacent vertebral bodies. The intervertebral implant may have at least one end plate and an intermediate component which slides into engagement with the end plate. The intermediate component may be engageable with the end plate from an anterior approach, or a right or left lateral approach. The intermediate component can be a set of bearing surfaces which articulate to provide relative motion between two vertebral bodies, an elastic insert which deforms to provide motion between two vertebral bodies, or a rigid insert which prevents relative motion between two vertebral bodies. The intermediate component is replaceable with a different intermediate component which provides a different function. The present invention also provides one or more retaining members which snap into engagement with the end plate and secure the intermediate component to the end plate.

CROSS-REFERENCE TO RELATED APPLICATIONS [0001] This application claims the benefit of the following: [0002] U.S. Provisional Application No. 60,720,513, filed Sep. 26, 2005, which carries Applicants' Docket No. MLI-45 PROV and is entitled MODULAR ARTICULATING AND FUSION SPINAL DISC IMPLANT SYSTEM; [0003] U.S. Provisional Application No. 60/720,514, filed Sep. 26, 2005, which carries Applicants' Docket No. MLI-46 PROV and is entitled UNIVERSAL SPINAL DISC IMPLANT SYSTEM FOR PROVIDING INTERVERTEBRAL ARTICULATION AND FUSION; and [0004] U.S. Provisional Application No. 60/741,513, filed Nov. 30, 2005, which carries Applicants' Docket No. MLI-50 PROV and is entitled SYSTEM AND METHOD FOR INTERVERTEBRAL IMPLANT DELIVERY AND REMOVAL. [0005] All of the foregoing are incorporated herein by reference. BACKGROUND OF THE INVENTION [0006] 1. The Field of the Invention [0007] The present invention relates generally to spinal orthopedics, and more precisely, to intervertebral implants. [0008] 2. The Relevant Technology [0009] Severe back pain can be caused by a number of different ailments, including spinal stenosis, degenerative disc disease, spondylolisthesis, and the like. Many such ailments can be corrected by controlling or limiting relative motion between the affected vertebrae. Accordingly, a variety of devices including artificial discs and fusion devices have been proposed. [0010] Such devices are limited in that they typically provide only one mode of correction. Many such devices cannot be replaced or corrected. This is particularly true with intervertebral implants, in which bone-growth is often stimulated to integrate the implants with the surrounding bone tissue. Thus, if the device fails to solve the problem, there may be no other recourse for the patient. [0011] Further, many known devices are expensive or difficult to manufacture, or are difficult to implant. Some known intervertebral devices require the adjacent vertebrae to be distracted excessively, thereby endangering the surrounding ligaments and other connective tissues. Accordingly, there is a need in the art for a device that remedies these problems. Such a device would considerably enhance outcomes for patients with spinal disorders. BRIEF DESCRIPTION OF THE DRAWINGS [0012] Various embodiments of the present invention will now be discussed with reference to the appended drawings. It is appreciated that these drawings depict only typical embodiments of the invention and are therefore not to be considered limiting of its scope. [0013] FIG. 1 is a perspective view illustrating a portion of a spine. [0014] FIG. 2 is a perspective lateral view of one embodiment of a total disc implant implanted in the spine, comprising inferior and superior end plates, inferior and superior bearings, and a plurality of clips. [0015] FIG. 3 is a perspective anterior view of the total disc implant of FIG. 2 in an disassembled state. [0016] FIG. 4 is a bottom elevation view of the clip shown in FIG. 3. [0017] FIG. 5 is a top elevation view of the clip shown in FIG. 3. [0018] FIG. 6 is a perspective side view of the clip shown in FIG. 3. [0019] FIG. 7 is a perspective posterior view of the bone engaging side of the inferior end plate shown in FIG. 3. [0020] FIG. 8 is a lateral end view of the inferior end plate shown in FIG. 3. [0021] FIG. 9 is a perspective anterior view of the bearing engaging side of the inferior end plate shown in FIG. 3, and one clip. Continue reading...
