The tap arrangement is constructed and arranged for anchoring within a bone, in fluid flow communication with the cavity.

In preferred applications, the cannula arrangement is provided in communication with a medical access port and/or infusion pump arrangement. A preferred tool is described, for implanting the apparatus in a bone of the subject.
