Multi-spatial force field
From Memory Alpha, the free Star Trek reference
A multi-spatial force field is a type of advanced force field.
When The Doctor's mobile emitter and DNA from Ensign Mulcahey was assimilated by Seven's nanoprobes in 2375 following a transporter accident, One, a drone possessing 29th century technology was the result. Among the many advanced capabilities One possessed was a personal multi-spatial force field.
During a Borg attack on USS Voyager, One boarded the attacking Borg sphere, interfaced with the ship's navigation controls and steered the ship into a nearby stellar phenomena, destroying the ship. One escaped destruction himself aided by his personal multi-spatial force field. (VOY: "Drone")
It may be somehow related to the technology in multispatial probes.
