An introducer can be used to implant a distractible intervertebral body fusion device into a patient's disc space and expand the device. Introducer includes a body 100 including a handle and a sleeve. Handle includes a slot for containing an actuation tool. A drive shaft and a securing shaft can extend through sleeve between a proximal end of the sleeve adjacent slot and a distal end of the device. At proximal end, actuation tool can connect to drive shaft where drive shaft extends through an opening in body. Drive shaft can extend out of an opening at distal end to engage a worm gear, drive shaft, or other actuation member of distractible device. Securing shaft can engage the device to stabilize the device during distraction. Activation of the actuation member rotates the drive shaft, which expands the distractible device.

A spinal implant system, specifically an intervertebral spacer. The system is designed to change its physical conformation from a minimal profile to an expanded state, enabling it to be placed through a smaller incision and operative cannula. The ability to change from a minimal profile to an expanded state may be accomplished through pivoting of support bodies, or expansion through a screw system, or sliding of the support bodies perhaps along an oblong surface. The system will allow for long-term promotion of osteointegration.

Method of using instruments and interbody spinal implants to enhance distraction

Номер: US20120239151A1
Автор: Chad J. Patterson, Peter F. Ulrich, JR.
Принадлежит: Titan Spine Inc

A method of using an interbody spinal implant by implanting the spinal implant into a patient in need of the spinal implant. The method includes accessing the disc space of the patient and locating the center of the disc space. The disc space is incised by making a window in the annulus of the disc space for insertion of the spinal implant. The endplates are cleaned of all cartilage and the disc structure, which is encapsulated by the annulus, is removed while avoiding damage to the endplate structure of the vertebrae. Optionally a size-specific rasp is selected and the disc space is cleared of all soft tissue and cartilage. Optionally the disc space is distracted by sequentially expanding it with distractors of progressively increasing heights. A spinal implant having a pre-determined size sufficient to balance frictional fit and elongation of the annulus is selected and seated in the disc space.

An implant (100, 200, 300, 400) includes a base (10), and a sequence of at least two segments including a first segment (12) and a last segment (14). The first segment (12) is pivotally linked to base (10). Adjacent segments are interconnected at pivotal connections (18). A bolt (20) has a threaded shaft (22) and a head (24). The threaded shaft (22) is engaged in a threaded channel (26) of the base (10) so that rotation of the bolt (20) about a central axis of the threaded shaft (22) varies a degree of overlap between the base (10) and the bolt (20). The last segment (14) and the head (24) define therebetween a spherical bearing (28). Rotation of bolt (20) thus varies a distance between spherical hearing (28) and hinge pin (16), thereby causing deflection of the sequence of segments.

An apparatus is designed to attach an implant to bone in a manner that permits rotational adjustment of the implant about multiple axes prior to securement via the apparatus. The apparatus includes separate rotational and translational fasteners that can be individually locked to independently restrict rotation and translation of the implant relative to the bone. The rotational fastener includes an interpositional member, an expandable engagement member, and a rotational locking member that urges the expandable engagement member to advance along the interpositional member. The resulting expansion of the engagement member causes it to engage the implant. The rotational fastener is slidable along a fixation member implanted in the bone until the translational fastener is applied to restrict relative translation between the rotational fastener and the bone.
