French surgeon who was the first to perform the ligation operation for aneurysms (bulges in the wall of an artery) since the Greek physician Antyllus performed them in the second century a.d. In a ligation operation, the artery is tied off with thread or wire to keep it from bursting. Anel also invented several surgical instruments, including the fine point syringe in 1714.
