Patrick McCarthy, MD, Chief of Cardiac Services, Northwestern Memorial Hospital designed the McCarthy Mini Sternotomy Retractor in conjunction with Kapp Surgical Instrument, Inc. This self-retaining retractor was designed to provide excellent exposure for a variety of valve operations, Maze procedure, or other intra cardiac procedures. It can also be used for mini sternotomy or coronary artery bypass operations or for mini sternotomy procedures depending upon the patient’s size. The removable lift attachment allows for better exposure for valve procedures.
