The Cosgrove Retractor is a unique heart retractor designed and proven specifically for heart valve surgery. It provides surgeons with the greatest visualization of the operative field, plus exceptional and consistent exposure of the right and left atrium, tricuspid valve and mitral valve, for surgical repair or replacement, while reducing the need for surgical assistance. The readily detachable, self-retaining atrial retractor requires placement only during the intracardiac portion of the procedure. The universally adjustable atrial retractor blades are made of durable, malleable surgical stainless steel. Several styles and sizes of retractor blades are available. Kapp provides the Cosgrove Retractor System mounted on a Cooley sternum retractor or custom mounted on any other sternum retractor, on request.
