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 58):
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 near a lower end of the tool, the bone anchor comprising:\n an anchoring member comprising a distal portion and a proximal portion opposite the distal portion, the distal portion to be attached to the patient bone in an anchoring manner; and a head to be coupled to and located near the proximal portion of the anchoring member and to couple to the elongated implant, the head comprising:\n a proximal region with a proximal end, and a distal region opposite the proximal end, the proximal portion of the anchoring member extending distally from the distal region of the head; \n a first arm and a second arm spaced apart from the first arm to define a channel therebetween to receive the elongated implant to couple the head to the elongated implant, the channel extending distally from the proximal end of the head; \n a helically wound thread defined in an inner surface on opposite sides 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 at least the first arm; and \n a horizontal radiused slot extending along at least a portion of the outer surface in a direction perpendicular to the longitudinal center axis of the head and radially spaced therefrom, the slot to receive the attachment structure when the bone anchor is coupled to the tool, the slot located near the proximal end of the head, and the proximal end of the head having a top surface thereon \n wherein the horizontal radiused slot comprises a proximal boundary comprising a radially inner extent and a radially outer extent radially outward of the radially inner extent, wherein the radially outer extent is distal the radially inner extent.
