Abstract

An apparatus for introducing a bone portal into a bone is described herein. An example apparatus for introducing portals into bone includes a stylet and a handle. The stylet is configured to support an infusion tube assembly. The infusion tube assembly comprises a bone portal. The handle is drivingly coupled to the stylet by a release mechanism. The release mechanism comprises a bone probe that, in a first configuration, extends generally parallel to the stylet. The release mechanism is operative to uncouple the driving coupling between the handle and the stylet upon axial motion of the bone probe relative to the handle. The stylet and bone probe are movable apart from one another to a second configuration.
