Thermal Surgery Expanded To Cardiac Procedures

(BUSINESS WIRE) Frank Shannon, M.D., a cardiothoracic surgeon at Beaumont Hospital in Royal Oak, Michigan performed the first cardiac surgery using Domain Surgical's thermal surgical FMwand Ferromagnetic Surgical System.

Dr. Shannon used the FMwand in a re-do open-heart operation in a 68-year-old woman who had undergone previous replacement of her aortic valve and bypass of her clogged coronary arteries. Within two years of this procedure, she had developed an abnormal collection of blood outside the walls of her aorta, which is often referred to as a “pseudo-aneurysm.” The walls of a pseudo-aneurysm are very thin and prone to rupture with manipulation or cautery.

“Using the FMwand, I was able to separate this delicate pseudo-aneurysm from the surrounding heart, lung and arteries without rupture or damage to these adjacent structures,” said Dr. Shannon. It "functioned like a 'hot, cold scalpel' in that the indistinct boundaries between adjacent scarred tissues were clearly separated with minimal bleeding and no significant collateral damage. This differs from traditional electrocautery, which 'burns' the tissue to prevent bleeding and creates tissue separation by heat damage to adherent structures."

The FMwand consists of a wire loop with a proprietary coating that, when activated, heats instantly, and when deactivated, quickly cools.
