This invention relates to an apparatus and method forinfusing fluids to and aspirating tissue from anintraosseous site. The apparatus is comprised of aninfusion device coupled to an introducer with a releasemechanism that removes the infusion device once it haspenetrated the bone a predetermined depth. As theintroducer is withdrawn, the infusion device remains in thebone. The ball release mechanism and other aspects of theapparatus can be modified to yield different penetrationdepths. The present invention also relates to a method andapparatus for locating the site of infusion and forrelieving strain and stress on the infusion site. Thetemplate patch uses a key anatomical feature of the bone asa reference point to a target zone for infusion that islocated a predetermined distance away from the feature.The template patch has a tube clamp and a covering thatprotect the infusion site from external forces.
