Abstract:
1. A separating system for detaching a pacing lead from a patient, comprising: a sheath having a proximal end and a distal end; and a separating assembly coupled with the distal end of the sheath, the separating assembly comprising a tip and a separator having a separating mechanism, wherein the tip and the separator are coupled via a slot and a key configuration, thereby allowing relative rotational movement of the tip and the separator, wherein the separator comprises the slot in its circumference, wherein the slot includes a first end, a second end, and a length, wherein the length of the slot extends between the first end and the second end for less than 360 degrees the circumference of the separator; wherein the separating mechanism comprises a circular distal separating edge, the tip comprises a blunt distal end and is configured without a cutting surface, and each of the sheath, the tip, and the separator are configured for placement over the pacing lead; and wherein the slot and key configuration of the separating assembly allows the separating assembly to switch between a deployed configuration where the circular distal separating edge of the separating mechanism is exposed distally past the distal blunt end of the tip in response to rotation of the sheath in a first direction and an undeployed configuration where the circular distal separating edge of the separating mechanism is proximal of the blunt distal end of the tip in response to rotation of the sheath in a second direction opposite the first direction.
