SPINAL JOINT IMPLANT DELIVERY DEVICE AND SYSTEM
First Claim
Patent Images
1. An apparatus for guiding a fixation member to a cervical disc joint space in a spine in an ACDF procedure, the apparatus comprising:
- a delivery device comprising;
an anchor shaft comprising a central lumen defining a longitudinal axis, a distal portion and a proximal portion extending from the distal portion;
a guide member operably associated with the anchor shaft, the guide member defining a first lumen coaxial with the central lumen, two angled lumen offset from the first lumen and at least one fixation member engagement feature; and
a fixation member having at least one threaded opening and at least one guide member engagement feature such that when the guide member engagement feature receives the fixation member engagement feature, the engagement hinders rotation of the fixation member relative to the guide member.

Abstract
Provided herein are devices, systems, apparatus and methods for accessing the cervical spine via an anterior approach and implanting a spinal fixation member between two vertebrae of the cervical spine in the disc or intervertebral joint space, such as in an ACDF procedure. The delivery device includes a distal end that can be anchored to the spinal fixation member. Once anchored to the spinal fixation member, the delivery device is operable to both advance and attach the spinal fixation member within a cervical disc joint space.

11. A system for guiding and securing a fixation member to a cervical disc joint space in a spine in an ACDF procedure, the system comprising:
-
a fixation member delivery device including; an anchor shaft comprising a central lumen defining a longitudinal axis, a distal portion and a proximal portion extending from the distal portion; and a guide member operably associated with the anchor shaft, the guide member defining a first lumen coaxial with the central lumen, two angled lumen offset from the first lumen and at least one fixation member engagement feature; and a fixation member having at least one threaded opening and at least one guide member engagement feature such that when the guide member engagement feature receives the fixation member engagement feature, the engagement hinders rotation of the fixation member relative to the guide member; and a drive member having a first end operably associated with the guide member adjacent the anchor shaft. - View Dependent Claims (14, 15, 16, 17, 18, 19)

12. The system of claim 12 wherein the device further comprises a rod member having at least one threaded end extending at least partially through the central lumen of the anchor shaft to releasably engage the threaded opening of the fixation member.
-
13. The system of claim 13 wherein the device further comprises a handle, the handle operably coupled to the proximal portion of the anchor shaft and rotatably coupled to the rod, wherein rotation of the rod releasably engages the rod with the fixation member.

20. A method of implanting a spinal fixation implant, the method comprising:
-
advancing a delivery apparatus into a disc joint space between two adjacent vertebrae in an ACDF procedure, the delivery apparatus comprising; an anchor shaft comprising a central lumen defining a longitudinal axis, a distal portion and a proximal portion extending from the distal portion; a guide member operably associated with the anchor shaft, the guide member defining a first lumen coaxial with the central lumen, two angled lumen offset from the first lumen and at least one fixation member engagement feature; and a fixation member having at least one threaded opening and at least one guide member engagement feature such that when the guide member engagement feature receives the fixation member engagement feature, the engagement hinders rotation of the fixation member relative to the guide member; advancing a drill/drive member adjacent the delivery apparatus, the drill/drive member having a fastener releasably attached to a first end of the drill/drive member; and advancing the fastener through the one of the two angled lumen of the guide member to attach the fixation member to at least one of the two adjacent vertebrae. - View Dependent Claims (21, 22, 23)
