Shares in a little known Swedish medtech company jumped as much as 15% on Tuesday following news of its involvement in the world’s first ever pig-to-human heart transplant.

Machinery developed by Xvivo Perfusion AB helped surgeons at the University of Maryland Medical Center successfully transplant a genetically modified pig’s heart into a 57-year-old man last Friday, according to the company.
