Abstract
Penetrator assemblies that include an outer penetrator and a removable inner trocar. In some of the penetrator assemblies, the removable inner trocar has a handle including a surface with a series of discs formed along a longitudinal axis, and the outer penetrator has a flange operable to engage an insertion site proximate the bone marrow. Some of the penetrator assemblies include a connector having a recess extending toward the cutting tip and through which a longitudinal axis of the outer penetrator extends, the recess configured to receive a portion of a shaft to enable rotation of the penetrator assembly by a powered apparatus or power drill.
