Lecretia Seals' widower Matt Vickers said she would be "very happy" to see the End of Life Choice Bill voted through Parliament.
"I am very proud of Lecretia," Vickers said.
"She is no longer here to see this result, but I think if she were still here she'd be very happy."
He said it was fantastic to see the contentious bill voted through Parliament, following three previous attempts at a bill over the past three decades.
It was also great to see that support for the bill had remained consistent, with a "healthy" majority of MPs approving the bill, with a similar amount of approval in the bill's second reading.
