Abstract:
A percutaneous access device includes an inner tube and an outer tube disposed about at least a portion of the inner tube. The outer tube may be sized to span from a skin incision in a patient to a site proximate the spine of the patient. The distal end of the outer tube may be adapted to releasably engage a bone anchor. The inner tube may be adjustable relative to the outer tube between a first position and a second position in which the distal end of the inner tube contacts the bone anchor. A bone anchor assembly includes a bone anchor having a distal bone engaging portion and a receiving member having a recess for receiving a spinal fixation element. The proximal end of the receiving member may have an arcuate groove formed on an exterior surface thereof to facilitate connection of an instrument to the receiving member.

Claim (Index 52):
A bone anchor to anchor an elongated implant to a patient bone and threadably engage with a closure plug, the bone anchor further to couple with a tool comprising an attachment structure, the bone anchor comprising:\n an anchoring member comprising a distal portion and a proximal portion opposite the distal portion, the distal portion to attach to the patient bone in an anchoring manner; and a head coupled to the proximal portion of the anchoring member, the head to couple to the elongated implant, the head comprising:\n a proximal end and a distal end opposite the proximal end, the proximal portion of the anchoring member extending into the distal end such that the head is coupled to the proximal portion of the anchoring member; \n a first arm and a second arm spaced apart from the first arm to define a channel to receive the elongated implant to couple the head to the elongated implant, the channel extending distally from the proximal end; \n a helically wound thread defined in an inner surface of the channel, the inner surface facing radially inward towards a longitudinal center axis of the head, the helically wound thread to threadably engage with the closure plug when the closure plug is received in the channel; \n an outer surface facing radially outward relative to the longitudinal center axis of the head, the outer surface being on the first arm; and \n a horizontal radiused slot near the proximal end of the head and extending along at least a portion of the outer surface in a direction perpendicular to the longitudinal center axis of the head, the slot to receive the attachment structure when the bone anchor is coupled to the tool; \n wherein the slot comprises a boundary that comprises a structural configuration that interacts with the attachment structure to inhibit radially outward displacement of the attachment structure from the slot in which the attachment structure is received; and wherein the structural configuration comprises a lip structure.
