Retractable separating systems and methods
First Claim
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.

Abstract
A method for detaching an object from a patient includes providing a tool having a sheath, and a separating assembly operably coupled to a distal end of the sheath. The separating assembly includes a separator moveably coupled to a tip via a threadable connection. The separating assembly is placed near patient tissue that is attached to the object, the sheath is rotated to move the separator distal to the tip, and the separator is applied to the patient tissue that is attached to the object, so as to separate the tissue. A separating system includes a sheath, and a separator threadably coupled with a distal end of the sheath. The separator is adapted to switch between a first configuration where a separating mechanism is deployed, and a second configuration where the separating mechanism is undeployed.

8. A separating system for detaching an object 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 an outer band having a blunt distal edge, the separating assembly further comprising a cutter having a distal cutting edge and a portion that is coaxial with the outer band; wherein the cutter and the outer band 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; and wherein the slot and key configuration facilitates switching between a deployed configuration where a portion of the cutter is exposed and an undeployed configuration where the portion of the cutter is unexposed. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. 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 an outer band having a blunt distal end that is configured without a cutting edge, and the separating assembly further comprising a cutter having a distal cutting edge and disposed at least partially within the outer band, 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 the cutter 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 cutter; wherein each of the sheath, the outer band, and the cutter 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 distal cutting edge of the cutter is exposed distally past the blunt distal end of the outer band 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. - View Dependent Claims (16, 17, 18, 19, 20)
