1. An apparatus, comprising:
- (a) an elongated shaft, wherein the elongated shaft comprises;
(i) a distal end,(ii) a proximal end,(iii) a curved region between the proximal and distal ends,(iv) an elongated tubular inner sheath, and(v) elongated tubular outer sheath, the inner sheath being positioned within the outer sheath;
(b) a handle joined to the proximal end;
(c) a longitudinal interior channel extending through the shaft and the handle;
(d) an actuator element slidably mounted within a slot on the handle; and
(e) an expandable dilator slidably disposed around a portion of an exterior of the elongate shaft;
further comprising an extensible and retractable guidewire movably mounted within the interior channel;
wherein the guide wire is reversibly movable between a retracted position and an extended position.
