content: The Chitwood Knot Pusher also referred to as the knot slider was developed by Dr. W. Randolph Chitwood, Jr. around 1996 for the repair and replacement of diseased heart valves while employing minimally invasive surgical procedures. In the August 2000 publication of <i>Operative Techniques in Thoracic and Cardiovascular Surgery</i>Chitwood's article "Video Assisted Mitral Valve Surgery: Using the Chitwood Clamp" the author describes how the clamp works. "...the knot slider was developed to position and tighten extracorporeally made knots deep within the chest. The hook operates much like a "tail hook" on an aircraft carrier-based jet and is used to trap the suture outside the chest after the closure arm is applied by squeezing the handle. Then the "thrown" knot is delivered to the valve annulus or leaflet by sliding while the assistant holds the proximal suture..." This instrument can be used for both Video-assisted thoracoscopic surgery (VATS) and Minimally invasive surgery (MIS)
