Abstract
A mechanism for guiding an instrument to and locating it at a surgical site comprising a flexible, movable, elongated guide having a proximal end constructed to receive a projecting portion of a surgical instrument and a distal end constructed to receive a flexible leader. There is at least one dilating portion located between the proximal and distal ends to dilate an area at the site to which the surgical instrument is being guided before the instrument reaches the site and while the guide is pulled in the direction of the distal end to facilitate locating the instrument in the area without injuring adjacent tissue.
