Systems for and methods of fusing a sacroiliac joint
First Claim
1. A sacroiliac joint fusion system comprising:
- a) a joint implant comprising;
a longitudinal axis extending between a proximal end and a distal end of the joint implant; and
a first bore extending non-parallel to the longitudinal axis;
b) an anchor element configured to be received in at least one of a sacrum or an ilium; and
c) a delivery tool comprising;
i) an implant arm comprising a shaft extending between a proximal end and a distal end of the implant arm and a handle at the proximal end, the distal end of the implant arm configured to releasably couple to the proximal end of the joint implant; and
ii) an anchor arm comprising an anchor guide coupled to the implant arm via a distal articulating member and a proximal articulating member, the distal articulating member rotatably coupled with implant arm at a first end and rotatably coupled with the anchor guide at a second end, the proximal articulating member slidably coupled with the implant arm at a third end and configured to slidably translate distal-proximal along the shaft of the implant arm, the proximal articulating member rotatably coupled with anchor guide at a fourth end, the anchor guide configured to align the anchor element in a trajectory such that the anchor element will be received in the at least one of the sacrum or the ilium when the anchor element is guided by the anchor guide,wherein, when the third end of the proximal articulating member is positioned in a proximal-most position, the anchor guide is configured to align the anchor element in the trajectory, and when the third end of the proximal articulating member is positioned in a distal-most position, the anchor guide is configured to align the anchor element in the trajectory.

Abstract
A sacroiliac joint fusion system including a joint implant, anchor element and delivery tool. The joint implant includes a bore extending non-parallel to the implant longitudinal axis. The anchor element is for receiving in the bore. The delivery tool includes an implant arm and anchor arm. The implant arm distal end is releasably coupled to the joint implant proximal end so the implant arm longitudinal axis is coaxial or parallel with the implant body longitudinal axis. An anchor arm distal end is engaged to the anchor element proximal end. The anchor arm is coupled to the implant arm such that the anchor element longitudinal axis is coaxially aligned with the bore longitudinal axis when the implant arm distal end is releasably coupled with the implant proximal end and the anchor arm distal end is engaged with the anchor element proximal end.
