Abstract
An active annuloplasty ring holder having a template that can be folded or pivoted to the side allowing the template to align longitudinally with the handle and enter the patient's chest through a small incision. The holder may include a mechanism to remotely detach sutures fastening the ring to the holder, thereby detaching the ring while avoiding the risk associated with introducing a scalpel into the operating field. A detachment mechanism may include a movable pin actuated by a pull wire that releases a plurality of holding sutures, or a hot wire, knives, or pull wire that severs the sutures. The holder may have a built-in light source for better visualization of the ring inside the heart. The holder may also have an optical means of visualizing the inside of the heart from the proximal end of the handle.
