1. A separating system for detaching a pacing lead from a patient, comprising:
a sheath having a proximal end and a distal end;
a handle coupled with the proximal end of the sheath, the handle being configured to be manipulated by an operator to rotate the sheath; and
a separating assembly coupled with the distal end of the sheath, the separating assembly comprising a cutter having a distal cutting edge, the separating assembly further comprising an outer band having a blunt distal end, wherein at least a portion of the outer band is disposed external and coaxial to the cutter, wherein the outer band and the cutter are coupled via a slot and key configuration, thereby allowing relative rotational movement of the outer band and the cutter, wherein one of the cutter and the outer band comprises a channel of the slot and key configuration in its circumference, wherein the channel includes a first end, a second end, and a length, wherein the length of the channel extends between the first end and the second end for less than 360 degrees the circumference of the one of the cutter and the outer band;
wherein each of the sheath, the outer band, and the cutter are configured for placement over the pacing lead;
wherein the slot and key configuration of the separating assembly is adapted to switch between a deployed configuration where the distal cutting edge of the cutter is exposed in response to manipulation of the handle and rotation of the sheath in a first direction and an undeployed configuration where the distal cutting edge of the cutter is proximal of the blunt distal end of the outer band in response to manipulation of the handle and rotation of the sheath in a second direction opposite the first direction.
