1. A method of fusing a sacroiliac joint, the method comprising:
- a) providing a joint implant comprising;
i) a body extending between an implant proximal end and an implant distal end; and
ii) a graft window extending non-parallel through the body and extending proximally from the implant distal end to define at least a portion of an opened distal end;
b) providing a delivery tool comprising;
i) an implant arm extending between a proximal implant arm end and a distal implant arm end, the distal implant arm end releasably coupled to the implant proximal end of the joint implant;
ii) an anchor am extending between a proximal anchor arm end and a distal anchor arm end, the distal anchor arm end releasably coupled to a proximal end of an anchor element; and
iii) a positioning arm coupling the implant arm and the anchor arm such that when coupled a delivery arrangement automatically exists such that the anchor element and the joint implant align in a trajectory such that the anchor element will be received within the graft window upon convergence of the anchor element and the joint implant, the implant arm being configured to rotate relative to the positioning arm about a longitudinal axis of the implant arm within a fixed range of rotation;
c) delivering the anchor element transversely through the sacroiliac joint; and
d) subsequent to step c), delivering the joint implant non-transversely into the sacroiliac joint such that the anchor element is positioned within the graft window of the joint implant, the joint implant in an orientation within the sacroiliac joint such that the body and the graft window are a generally within a plane defined by the sacroiliac joint.

Abstract
A sacroiliac joint fusion system including a joint implant, an anchor element and a delivery tool including an implant arm, an anchor arm, and a positioning arm coupling the implant arm and the anchor arm. The implant arm includes an implant shaft extending between a proximal end and a distal end of the implant arm. The anchor arm including an anchor shaft extending between a proximal end and a distal end of the anchor arm. The positioning arm coupled with the implant arm at a first end and coupled with the anchor arm at a second end.

13. A method of fusing a sacroiliac joint, the method comprising:
-
a) delivering an anchor element transversely through the sacroiliac joint; and b) subsequent to step a), delivering a joint implant non-transversely into the sacroiliac joint such that the anchor element and the joint implant are positioned in a pre-determined relationship relative to each other, wherein the pre-determined relationship is provided by a delivery tool comprising; i) an implant arm including a proximal implant arm end and a distal implant arm end, the distal implant arm end releasably coupled to the joint implant; ii) an anchor arm including a proximal anchor arm end and a distal anchor arm end, the distal anchor arm end releasably coupled to the anchor element; and iii) a positioning arm coupling the implant arm and the anchor arm such that when coupled a delivery arrangement automatically exists such that the anchor element and the joint implant align in a trajectory such that the anchor element and the joint implant will not contact each other during delivery of the joint implant non-transversely into the sacroiliac joint, the implant arm being configured to displace relative to the positioning arm within a fixed range of displacement, the displacement comprising at least one of rotation or translation. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25)
