INTRAMEDULLARY CATHETER ABSTRACT An intramedullary catheter is provided which is attached to a bone to permit the infusion of drugs, fluids, or the like, directly into the bone marrow for subsequent dispersion to the vascular system. The present invention contemplates an intra- medullary catheter, method of implanting such a catheter, and a method of fluid delivery to the vascular system through the bone marrow. The intramedullary catheter preferably includes a thread- ed conduit, a head attached to one end of the conduit, and a sealing membrane in the head overlying the conduit. The intra- medullary catheter is implanted in a bone, such as the iliac crest, with the conduit threadingly engaging the bone and the surrounding skin closed over the head and membrane. Fluids are delivered by inserting a needle through the membrane into communi- cation with the conduit for transport to the bone marrow. The present invention is particularly appropriate for patients who require long-term administration of medications as an alternative to intravenous delivery.
