IMPLANTS, SYSTEMS, AND METHODS FOR FUSING A SACROILIAC JOINT

摘要

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.

主权项

1. A sacroiliac joint fusion system comprising:
a) a joint implant comprising: a proximal end; a distal end; a longitudinal axis extending between the proximal and distal ends of the joint implant; and a graft window extending non-parallel to the longitudinal axis; b) an anchor element comprising a proximal end and a distal end, the anchor element configured to be received in the graft window of the joint implant; and c) a delivery tool comprising:
i) an implant arm comprising an implant shaft extending between a proximal end and a distal end of the implant arm, and a longitudinal axis extending between the proximal and distal ends of the implant arm, the distal end of the implant arm configured to releasably couple to the proximal end of the joint implant;ii) an anchor arm comprising an anchor shaft extending between a proximal end and a distal end of the anchor arm, and a longitudinal axis extending between the proximal and distal ends of the anchor arm, the distal end of the anchor arm configured to releasably couple to the proximal end of the anchor element; andii) a positioning arm coupled with the implant arm at a first end and coupled with the anchor arm at a second end, the implant arm being configured to rotate relative to the first end along the longitudinal axis of the implant arm within a fixed range of rotation, wherein, when the implant arm is coupled to the first end and the anchor arm is coupled to the second end, 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.
