Abstract
Abstract An apparatus and method for harvesting bone and bone marrow are provided. The apparatus may include a driver operable to be releasably engaged with an intraosseous device. The intraosseous device may include a cannula having a first end operable to penetrate bone and bone marrow and to allow retrieval of portions of bone and/or bone marrow. The cannula may have a second end operable to be releasably engaged with bone marrow sampling equipment. The apparatus may include a removable trocar. The removable trocar may have an inner channel operable to convey portions of bone and/or bone marrow. The removable trocar may have an inner channel and a side port communicating with the inner channel. The removable trocar may have a first end operable to penetrate bone and bone marrow.
