Abstract:
A dynamic fixation medical implant includes a longitudinal connecting member assembly having an elongate coil-like outer member and an inner cylindrical core attached to the outer member at only one end thereof. Some assemblies include a second longitudinal connecting member in the form of a rod that is fixed to the inner core and extends outwardly from the assembly. Certain assemblies include a threaded core or threaded inserts that cooperate with a helical slit of the coil-like outer member. Two or more cooperating bone screw assemblies attach to the connecting member assembly. The bone screw assemblies may include upper and lower compression members for affixing to and cradling the coil-like outer member only, allowing relative movement between the outer member and the inner cylindrical core. Press fit or snap-on features attach one end of the coil-like outer member to one end of the inner cylindrical core.

Claim (Index 1):
A pivotal bone anchor assembly for a securing a longitudinal connecting member to a bone, the pivotal bone anchor assembly comprising:\n a receiver including a lower body and a pair of upright arms extending upward from the lower body with opposed interior surfaces defining a receiver channel for receiving the longitudinal connecting member therebetween, the interior surfaces having a discontinuous mating structure for mating with a closure, the lower body defining a cavity in communication with the receiver channel and with a bottom surface of the receiver through a bottom opening and having an internal surface; a shank having an upper capture portion integral with a lower anchor portion that is threaded for attachment to the bone, the upper capture portion including an outer curvate surface and being configured for uploading into the receiver cavity through the bottom opening; a retainer disposed within the receiver cavity prior to the shank and engageable with the shank upper capture portion to capture and hold the shank upper capture portion within the receiver cavity with the lower anchor portion extending downward through the receiver bottom opening, the retainer being positioned between the shank upper capture portion and the receiver cavity internal surface and engageable with the receiver cavity internal surface; and an insert having an upper longitudinal connecting member engaging surface disposed within the receiver channel and a lower surface engageable with an outer surface of the retainer, the insert further having an overlapping arrangement with an interior surface in the receiver to inhibit upward movement of the insert within the receiver after the retainer has captured the shank in the receiver cavity, wherein the insert remains spaced apart from the shank upper capture portion in all degrees of pivotal motion for the shank with respect to the receiver.
