Abstract
Abstract A device and method for rapid access to the bone marrow for the infusion of drugs and other fluids into the bone marrow; sampling the bone marrow; and monitoring the physical properties of the blood and bone marrow. These operations may proceed sequentially or simultaneously. A "smart" controller may be utilized to direct or control these operations. An implantable intraosseous needle assembly and various means for injecting, utilizing, and extracting that assembly into a bone containing bone marrow are disclosed.
