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 (28) of an infusion/aspiration tube (35) has reached the trabecular bone (11), and a spring bias (39) ensures that the tip seals is the hole formed in cortical bone during the subsequent infusion or aspiration.

L'invention concerne un appareil et un procédé associés permettant d'injecter par perfusion des liquides et des médicaments dans la trabécule de l'os d'un patient, ou d'aspirer de la moelle de ladite trabécule. L'appareil permet à l'utilisateur de déterminer de manière fiable quand la pointe filetée élargie (28) d'un tube d'injection/aspiration (35) a atteint l'os trabéculaire (11), et un ressort (39) assure que la pointe bouche le trou formé dans l'os cortical, pendant l'injection ou l'aspiration.
