Claim:
1. A dilation system, comprising: a dilator assembly comprising a plurality of dilator segments, each dilator segment having a proximal end, a distal end, an inner side, and an outer side, the inner side of each of the dilator segments having a proximal tapered surface extending from the proximal end toward the distal end and a distal tapered surface extending from the distal end toward the proximal end; and an actuating mechanism having an upper wedge and a lower wedge axially moveable relative to one another, the upper wedge having a tapered surface corresponding to the proximal tapered surface of the dilator segments such that the tapered surface of the upper wedge is slidable along the proximal tapered surface of the dilator segments and the lower wedge having a tapered surface corresponding to the distal tapered surface of the dilator segments such that the tapered surface of the lower wedge is slidable along the distal tapered surface of the dilator segments, the upper wedge and the lower wedge being axially moveable relative to one another in a way to cause the dilator segments to move between a collapsed state and an expanded state, wherein the actuating mechanism further includes an actuating handle comprising:
