ligate

Tie off surgically

To ligate is to tie off with a ligature—a thread or wire used to bind something tightly.

The term appears most often in surgery, where surgeons ligate blood vessels to stop bleeding or close off ducts: The surgeon ligated the artery before making the incision.

In molecular biology, to ligate is to join DNA fragments using an enzyme.
