Abstract
Some introducer tools for bone portals have a handle coupled to a driving member by a force-limiting coupling. A bone portal comprising a bone-penetrating portion and a bone stop may be driven to a desired depth in bone when the force-limiting coupling allows application of force to the bone portal that is sufficient to drive the bone-penetrating portion of the portal into the bone but not sufficient to drive the bone stop significantly into the bone. Bone portals of various types are described herein. Various configurations for stylets suitable for use in introducing bone portals or otherwise penetrating bone and methods for inserting bone portals are also described herein.
