Multidimensional transporter device
A multidimensional transporter device was a technology capable of reconfiguring transporters for use in beaming from one parallel universe to another. ()

It was first observed in use by Starfleet in 2371, when  used it to kidnap Commander Benjamin Sisko, so that Sisko could take the place of , who had recently died. ()

The next year,  used a multidimensional transporter to visit Sisko and his son, Jake. Jennifer subsequently took Jake to the parallel universe, leaving a multidimensional transporter behind, as an invitation for Captain Sisko to follow them. Although Sisko attempted to take Major Kira and Chief O'Brien with him, he found that the device was only programmed to allow him to make the transition. While there, he assisted the  rebels, who were fighting against the Klingon-Cardassian Alliance, to complete construction on the . ()

In 2374,  used a multidimensional transporter to make the transition, during an attempt to steal the Orb of Prophecy and Change with Intendant . Major Kira was eventually able to convince Bareil to betray her counterpart, and abandon the plot to steal the orb. ()

In 2375, Rom left a PADD with the schematics for the multidimensional transporter, which Chief O'Brien had given him to study, out at his mother's house on Ferenginar, where Grand Nagus Zek found it. Stealing it, Zek traveled to the parallel universe in an attempt to find new financial opportunities, but was subsequently captured by the Alliance. Regent  held Zek hostage, promising to release him to Quark and Rom in exchange for a cloaking device, which did not exist in the parallel universe. Using another transporter device,  took the two Ferengi, along with the cloaking device, to the parallel universe, where they were able to free Zek. ()
