The positioning instrument may comprise an alignment guide having a device portal for insertion of a device therethrough. The positioning instrument may have an indicator probe having an extended arm, and a handle portion for maneuvering the positioning instrument. Another instrument may be a device for placement through the device portal of the alignment guide and to the target site. The device may comprise an implant insertion tool, an injection catheter, a cavity creation tool such as a bone drill, for example, or the device may be an implantable device.
