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.

Apparatus for infusing a liquid into, or aspirating marrow from, the trabecula of a patient\s bone, comprising: a base having a lower surface adapted for placement against the skin of a patient, adjacent to a bone of the patient, wherein a bore extends through the base, emerging in its lower surface

Apparatus for infusing a liquid into, or aspirating marrow from, the trabecula of a patient\s bone, comprising: a base having a lower surface adapted for placement against the skin of a patient, adjacent to a bone of the patient, wherein a bore extends through the base, emerging in its lower surface; and an elongated infusion/aspiration tube extending through the bore formed in the base, wherein the tube includes an upper end and an enlarged lower end adapted to penetrate the patient\s skin and bone, the enlarged lower end including a port communicating with the tube\s hollow interior; wherein, in use, the base is positioned with its lower surface abutting against the patient\s skin, adjacent the bone, and the infusion/aspiration tube is then rotated about its longitudinal axis, to advance the tube\s enlarged lower end through the cortical bone and into the trabecular bone, the reaching of the trabecular bone being sensed by a substantial reduction in resistance to continued rotation of the tube; and wherein the liquid can thereafter be infused into, or marrow aspirated from, the trabecular bone through the tube and its port.
