## Abstract

A system for performing a minimally invasive interventional fusion procedure on a sacroiliac joint of a patient. The system may include a disposable sterile packed implant and kit including access, bone cutting, accessory and extraction instruments.

## Claims

### Claim 1

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.

### Claim 2 (depends on 1)

The system of claim 1, wherein the tubular body has a generally circular cross section perpendicular to the cannula axis.

### Claim 3 (depends on 1)

The system of claim 1, wherein the working cannula further comprises at least one of irrigation, suction, lighting, electrocautery, bone engaging features, visual markers, radiographic markers, or electrophysiologic monitoring electrodes and electrical insulation.

### Claim 4 (depends on 1)

The system of claim 1, wherein the guide rail assembly further comprises a fastening portion coupled with the ring structure and configured to fix an arrangement between the guide rail assembly and the working cannula.

### Claim 5 (depends on 4)

The system of claim 4, wherein the fastening portion is connected to the ring structure such that when the ring structure is seated at the proximal end of the working cannula the fastening portion is positioned up against and engaged with an outer surface of the tubular body.

### Claim 6 (depends on 1)

The system of claim 1, wherein the guide rail assembly is configured to be rotatable in relationship to the working cannula with an infinite resolution of rotational positions.

### Claim 7 (depends on 1)

The system of claim 1, wherein the guide rail assembly is configured to be rotatable in relationship to the working cannula with a finite resolution of indexable rotational positions.

### Claim 8 (depends on 1)

The system of claim 1, further comprising a broach and wherein the guide rail assembly is configured to guide the broach up to and into the sacrum and ilium while constraining the trajectory and orientation of the broach relative to the sacroiliac joint.

### Claim 9 (depends on 1)

The system of claim 1, wherein the pair of guide rails being arranged, configured and sized to guide the implant along the implantation trajectory while maintaining the predetermined implant orientation includes the pair of guide rails having a shape, size and arrangement which generally match an outer profile of the implant body.

### Claim 10 (depends on 9)

The system of claim 9, wherein the implant body includes an extruded X-shape having four gaps defined in between four arms of the implant and wherein each of the pair of guide rails includes a guide rail outer surface which closely approximates a shape, size and arrangement of at least two opposing gaps of the four gaps thereby preventing gross rotation of the implant about an implant axis during guidance of the implant by the pair of guide rails.

### Claim 11 (depends on 9)

The system of claim 9, further comprising an inserter tool having a distal end with an implant-shape-matching portion configured to deliver the implant into the sacroiliac joint, wherein the implant-shape-matching portion is guided by the pair of rails.

### Claim 12 (depends on 1)

The system of claim 1, wherein the working cannula further comprises an attachment point configured to couple to a handle or to a surgical table either directly or via an articulating arm surgical tool holder.
