Patent attributes
A long-pitch, helical anchor includes splines radially extending and helically progressing circumferentially around and along the arcuate length of a curved center line (central curve). The center line may progress along the curved length of the anchor with all splines meeting near the center line. In other embodiments, the center line passes along the center of a lumen or channel from which the splines extend radially along the length. A solid point acts as a cutting edge on a distal end of the anchor. All the splines converge to the center line. Installation may be with or without a stabilizing frame, such as may be used to fill gaps and promote bone growth between joined members. The anchors may be used directly to connect and provide compression between two bones or bone structures.
