Abstract
A medical stapling device in which, upon activation, spaced lugs on a driver advance open staples along a track between two grooved rails frictionally holding the staples so that the leading staple will be closed around an anvil at the end of the track and can suture adjacent living tissue. Subsequently cam members which maintained the lugs in engagement with the staples as the lead staple was closed are biased by a spring to a position at which the lugs separate from and move around the staples as the driver is returned to its original position at which the lugs again engage subsequent staples along the track.
