Abstract
Apparatus and related method for infusing liquids and drugs into, or aspirating marrow from, the trabecula of a patient's bone. The apparatus enables the user to reliably determine when an enlarged, threaded tip of an infusion/aspiration tube has reached the trabecular bone, and a spring bias ensures that the tip seals the hole formed in cortical bone during the subsequent infusion or aspiration.
