Zusammenfassung:Devices and methods for the removal of bone implant tips from within a bony structure in a body. The device or method includes a shaft with an internal grasping feature capable of being inserted while remaining in an un-expanded, un-deployed state. This permits a surgeon or operator to insert the device while in a small profile state, avoiding or reducing damage to adjacent bone tissue during insertion. Upon insertion of the shaft to the proper position within a patient's bone, the grasping feature may then be expanded or deployed from the distal end of the shaft by a surgeon or operator using an actuator in a handle attached to the proximal end of the shaft. Following deployment, the grasping feature may be used to manipulate and/or remove a bone implant tip from a patient's bone tissue. Embodiments of the grasping feature include one or more hooks, wires, articulating fingers, and/or net-based designs formed of metal, polymer, composite, or a combination thereof. The grasping feature may also include an adhesive-based design formed of bone cement, protein-based glue, or other adhesive material with the purpose of grasping or manipulating a bone implant tip within bone tissue.
