Abstract
Abstract Apparatus and methods are provided to access bone marrow at various target areas. Such apparatus may include an intraosseous device operable to penetrate bone at a selected target area and a depth limiter operable to control depth of penetration of the intraosseous device into bone and associated bone marrow. A manual driver and a guide may be included to optimize optimum insertion of the intraosseous device at a selected insertion site on a sternum.
