Abstract
A medical implant assembly having at least two bone attachment structures cooperating with a dynamic longitudinal connecting member, the improvement wherein the connecting member includes: a first end, a transition portion, and a second end; a substantially rod portion extending longitudinally from the first end to the transition portion, and including a longitudinal axis and a substantially rigid core running substantially parallel with the longitudinal axis; a substantially cord portion joined with the rod portion and extending from the transition portion to the second end; and a substantially flexible jacket portion covering the rod and cord portions.
Claims17
A method of assembling a medical implant assembly having a longitudinal connecting member cooperating with a plurality of bone attachment structures, the method comprising:
- providing the longitudinal connecting member comprising:
- a rigid rod portion extending from a first end to a transition portion;
- a flexible cord portion joined with the rigid rod portion at the transition portion and extending from the transition portion to a second end;
- and
- a releasable end-blocker bumper portion, the releasable end-blocker bumper portion comprising a blocker portion and a tubular extension extending from the blocker portion;
- engaging the rigid rod portion with a first of the plurality of bone attachment structures;
- extending the flexible cord portion through a second of the plurality of bone attachment structures;
- and
- holding at least one outer planar side surface of the releasable end-blocker bumper portion while securing the releasable end-blocker bumper portion to the flexible cord portion.
