Abstract
A sacro-iliac implant system includes at least one implant including a body defining an outer surface and being disposed to space apart opposing articular surfaces of a sacro-iliac joint. The body is engageable with the opposing articular surfaces and the outer surface is compliant to a configuration of the opposing articular surfaces such that the body facilitates relative movement of the opposing articular surfaces. Methods of use are disclosed.
Claims20
A sacro-iliac implant system comprising:
- an instrument extending between opposite first and second ends and comprising an intermediate section therebetween;
- and
- at least one implant including a body extending between opposite proximal and distal ends, the proximal end engaging the intermediate section and the distal end engaging the second end, the body defining an outer surface and being disposed to space apart opposing articular surfaces of a sacro-iliac joint, wherein the body includes at least one agent and is engageable with the opposing articular surfaces and the outer surface is compliant to a configuration of the opposing articular surfaces such that the body facilitates relative movement of the opposing articular surfaces;
- wherein the body expands from a first, collapsed orientation having a first diameter to a second expanded orientation having a second diameter, the second diameter being 2 to 10 times greater than the first diameter, the body being pre-formed to have a non-uniform shape when the body is in the second orientation and no external force is applied to the outer surface.

A sacro-iliac implant system comprising:
- a bio-compatible material;
- at least one implant including a body extending between opposite proximal and distal ends, the body defining an outer surface and being configured to engage and space apart opposing articular surfaces of a sacro-iliac joint to facilitate relative movement of the opposing articular surfaces, the body including at least one biologically-active agent and being configured to expand from a first, collapsed orientation having a first diameter to a second inflated orientation having a second diameter that is 2 to 10 times greater than the first diameter, the body being pre-formed to have a non-uniform shape when the body is in the second orientation and no external force is applied to the outer surface, the outer surface being compliant to a configuration of the opposing articular surfaces such that the body is inflated with a fluid and moldable in situ to the configuration of the opposing articular surfaces;
- and
- a delivery instrument extending between opposite first and second ends and comprising an intermediate section therebetween, the instrument being configured to deliver the fluid to the body, the distal end engaging the second end and the proximal end engaging the intermediate section such that the instrument is detachably connected with the body.
