A spinal implant comprises an implant body extending between an anterior surface and a posterior surface. The implant body includes a first vertebral engaging surface and a second vertebral engaging surface. The implant body includes an outer surface that defines an oblique surface. A wall is connectable with the implant body and translatable relative to the oblique surface. Systems and methods are disclosed.

Spinal implant system and method

The present invention provides spinous process implants and associated methods. In one aspect of the invention, the implant includes at least one extension with a first part and a second part where at least one arm is coupled to each of the first part and the second part. The first part and the second part are movable from a compact to a distracted state. In another aspect, the present invention provides a second extension that is slidingly coupled to the first and second arms. The second extension further comprises a third part and a fourth part that move with the first and second part.

Telescoping interspinous fixation device and methods of use

An implantable device may be provided. The implantable device may comprise an upper assembly comprising a ramped base and a pair of opposing windows. The pair of opposing windows may extend upward from either lateral side of the ramped base. A gripping assembly may be disposed in each window. The implantable device may further comprise a lower assembly comprising a ramped base and a pair of opposing windows. The pair of opposing windows may extend down from either lateral side of the ramped base. A gripping assembly is disposed in each window. The implantable device may further comprise a ramped actuator assembly disposed between the upper assembly and the lower assembly. The ramped actuator may be configured to transition the implantable device from a collapsed form having a first height to an expanded form having a second height and wherein the second height is greater than the first height.

Spinous process fixation system and methods thereof

A device and method for performing interspinous fixation or spinal fusion is provided. The device may generally include a first plate and a second plate, each having an adjustable length, and a mechanical actuator for increasing or reducing the length of the plates and, correspondingly, the device. Operation of the mechanical actuator causes first and second inner expansion portions of each plate to simultaneously slide on an outer fixed portion of the plate, to increase or decrease (depending on the direction of operation of the mechanical actuator) the separation between the first and second inner expansion portions, and thus, lengthen or shorten the plates and device.

Expansion interspinous fixation device and method

A polyaxial interspinous fusion device is described. The polyaxial interspinous fusion device has a fixed anchor, a polyaxial anchor, and a bone spacer. The fixed anchor has a center ring, one or more fixed anchor arms projecting laterally from the center ring, and a barrel projecting transversely from the center ring. The polyaxial anchor has a socket ring and one or more polyaxial anchor arms projecting laterally from the socket ring, wherein the socket ring has a concave engagement surface. The bone spacer has a spacer head having a convex socket engagement surface that matches the concave engagement surface of the socket ring. The bone spacer also has one or more zip lock flanges extending transversely from the spacer head and one or more bone abutments extending transversely from the spacer head. The zip lock flanges and bone abutments of the bone spacer fit through the socket ring and the barrel of the fixed anchor fits through the socket ring. The zip lock flanges engage with the barrel when the zip lock flanges and bone abutments are inserted through the socket ring. When the polyaxial anchor engages with the spacer head, the polyaxial anchor has a polyaxial freedom of movement relative to the spacer head as a result of a ball and socket engagement between the concave engagement surface of the socket ring and convex socket engagement surface of the spacer head.

Polyaxial interspinous fusion implant and bone growth stimulation system

Disclosed is a device that is configured to be implanted adjacent interspinous processes of a patient. In one aspect, a spinal implant device comprises: a spacer region adapted to be positioned between first and second spinous processes of first and second vertebral bodies to limit movement of the first spinous process and the second spinous process toward one another; and an attachment region attached to the spacer region, the attachment region adapted to attach to the first spinous process via a fastener, the attachment region comprising a pair of pads having attachment elements that are configured to attach onto the spinous process
