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.
Claims32
A sacroiliac joint implant comprising:
- a distal end, a proximal end opposite the distal end, and a longitudinal axis extending centrally between the distal end and the proximal end,
- a first planar member comprising a first iliac member, a first sacral member extending from the first iliac member at a first midsection thereof, a first iliac side edge, a first sacral side edge opposite the first iliac side edge, a first iliac distal edge, a first sacral distal edge joined with the first iliac distal edge, a first iliac proximal edge, a first sacral proximal edge joining the first iliac proximal edge, a first iliac top surface, a first iliac bottom surface opposite the first iliac top surface, a first sacral top surface, and a first sacral bottom surface opposite the first sacral top surface, and a first aperture extending from the first iliac top surface and the first sacral top surface through the first planar member to the first iliac bottom surface and the first sacral bottom surface,
- wherein the first iliac top surface and the first sacral bottom surface each include at least one first fin extending between the proximal end and the distal end and terminating at a first distal section, the at least one first fin comprising a first trough and a first crest, the first trough positioned farther outward than the first crest from the longitudinal axis, the first distal section comprising an outward flaring of both the first trough and the first crest away from the longitudinal axis,
- a second planar member joined with the first planar member to form a generally X-shape cross-section transverse to the longitudinal axis.

A sacroiliac joint implant comprising:
- a distal end, a proximal end opposite the distal end, and a longitudinal axis extending centrally between the distal end and the proximal end,
- an iliac side, a sacral side adjacent the iliac side, a top surface extending across the iliac side and the sacral side, a bottom surface opposite the top surface and extending across the iliac side and the sacral side, an iliac side surface, a sacral side surface opposite the iliac side surface, a first aperture extending from the top surface to the bottom surface, a second aperture extending from the iliac side surface to the sacral side surface and extending through the first aperture, and
- wherein each of the sacral side and the iliac side includes, on the top surface, at least one first fin extending between the proximal end and the distal end and terminating at a first distal section, the at least one first fin comprising a first trough and a first crest, the first trough positioned farther outward than the first crest from the longitudinal axis, the first distal section comprising an outward flaring of both the first trough and the first crest away from the longitudinal axis.
A sacroiliac joint implant comprising:
- a distal end, a proximal end opposite the distal end, and a longitudinal axis extending centrally between the distal end and the proximal end, and an implant body extending a length between the distal and proximal ends and comprising:
- a central core portion disposed along the longitudinal axis,
- a first, second, third, and fourth fixation member each of which extends outwardly from and connects to the central core portion and each of which extends the length, wherein each of the first fixation member and the second fixation member comprises at least one exterior surface having at least one stepped projection disposed thereon and extending along the implant body between the proximal and distal ends,
- wherein each of the at least one stepped projection comprises a riser portion and a tread portion, the riser portion extending outward from the at least one exterior surface from which it is disposed and the tread portion extending generally perpendicular to the riser portion;
- and
- wherein each of the at least one stepped projection, while extending along the implant body between the proximal and distal ends, extends parallel to the longitudinal axis from the proximal end up until a transition point where each of the at least one stepped projection then forms a diverging angle to the longitudinal axis.

- and
- wherein each of the at least one trough, while extending along the implant body from the proximal end to distal end, forms a diverging angle to the longitudinal axis such that a distal trough portion is located farther from the longitudinal axis than a proximal trough portion.
