In Harry Potter and the Deathly Hallows, Voldemort uses Lucius Malfoy's wand after his own wand fails against Harry's. During the Seven Potters battle and subsequent attempts to kill Harry, Voldemort borrows Malfoy's wand, demonstrating his desperation to overcome the twin-core connection with Harry's wand. The other options (Yaxley, Wormtail, Bellatrix) were Death Eaters but Voldemort specifically sought and used Malfoy's wand.
