SYSTEMS FOR AND METHODS OF FUSING A SACROILIAC JOINT
First Claim
1. A system for fusing a sacroiliac joint, the system comprising:
- an implant assembly adapted to be inserted into the sacroiliac joint and having a distal end portion, a proximal end portion, and a body portion extending between the distal and proximal end portions, the body portion including first and second oppositely disposed side members, each side member being structured and arranged to expandably engage the sacroiliac joint following insertion therein;
means for expanding the first and second oppositely disposed side members into operative engagement with the sacroiliac joint;
a delivery tool for inserting the implant assembly into the sacroiliac joint; and
a tool interface formed in the implant assembly adapted to receive the delivery tool for inserting the implant assembly into the sacroiliac joint.

Abstract
Systems for and methods of fusing a sacroiliac joint are provided which include an implant assembly adapted to be inserted into the joint space defined by the bones of a sacrum and an ilium, a delivery tool and means for inserting the implant assembly into the joint. The implant assembly includes a body disposed intermediate distal and proximate end portions thereof and having oppositely disposed side members adapted to expandably engage the sacroiliac joint following insertion of the assembly into the joint space. A tool is provided and provides a means for placing the implant assembly adjacent the sacroiliac joint, inserting it into the joint space and expanding means are thereafter applied to expand the oppositely disposed side members into operative engagement with the joint.

13. A method of fusing a sacroiliac joint comprising:
-
positioning an implant assembly adjacent a sacroiliac joint having a joint space defined by bone material, the implant assembly comprising a distal end portion, a proximal end portion, and a body portion extending between the distal and proximal end portions, the body portion including first and second oppositely disposed side members, each side member being structured and arranged to expandably engage the sacroiliac joint following insertion therein; delivering the implant device into the sacroiliac joint space, the implant assembly being positioned in the joint space such that the first and second oppositely disposed side members are generally coplanar with a joint plane of the sacroiliac joint space; and expanding the first and second oppositely disposed side members into operative engagement with the bone material defining the sacroiliac joint space. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)
