Minimally invasive systems for and methods of preparing and fusing a sacroiliac joint during interventional procedures

A system for performing a fusion procedure on a sacroiliac joint defined between a sacrum and an ilium, the system comprising:

• a working cannula comprising a proximal end, a distal end, a tubular body extending between the proximal and distal ends, a cannula passageway defined within the tubular body and having a cannula axis extending therethrough;
• a guide rail assembly comprising a pair of guide rails extending generally parallel to each other from a ring structure, wherein the ring structure is configured to engage the proximal end of the working cannula and the pair of guide rails is configured to fit within the cannula passageway;
• an implant having a body extending between a distal end and a proximal end;
• and
• wherein the pair of guide rails are arranged, configured and sized to guide the implant along an implantation trajectory while maintaining a predetermined implant orientation.
