Abstract

The invention relates to tacking devices for use in minimally invasive surgery that have a quantity indicator on a distal end that can be seen through a scope and that show a number of fasteners remaining in the device. A surgeon can watch the delivery of fasteners while simultaneously seeing f a number of fasteners remaining. This allows a hernia mesh to be properly fixed into place without going astray during the delicate initial placement procedure and also for even spacing of the fasteners on the mesh. The patient's post-operative recovery progresses well, and excessive pain is avoided. Methods of the invention include viewing the surgical site via the scope while also viewing the indicator via the scope.
