Retractable separating systems and methods
First Claim
1. A device for removing an implanted object from a body vessel, the device 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 band;
a cutter having a distal cutting edge; and
a slot and key configuration coupling the cutter and the band, the slot and key configuration permitting relative rotational and translational movement of the band and the cutter, the slot and key configuration comprising a channel formed in a circumference of one of the cutter and the band, and the channel including a length that extends for less than 360 degrees between ends of the channel;
whereupon relative rotation of the band and the cutter, the slot and key configuration translates the cutter between a deployed configuration where a portion of the cutter is exposed from the band and an undeployed configuration where the portion of the cutter is unexposed from the band.

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.

11. A device for removing an implanted object from a body vessel, the device comprising:
-
a sheath having a proximal end and a distal end; a motor coupled to the sheath; and a separating assembly coupled with the distal end of the sheath, the separating assembly comprising; a band; a cutter having a distal cutting edge; and a slot and key configuration coupling the cutter and the band, the slot and key configuration permitting relative rotational and translational movement of the band and the cutter, the slot and key configuration comprising a channel formed in a circumference of one of the cutter and the band, and the channel including a length that extends for less than 360 degrees between ends of the channel; whereupon relative rotation of the band and the cutter, the slot and key configuration translates the cutter between a deployed configuration where a portion of the cutter is exposed from the band and an undeployed configuration where the portion of the cutter is unexposed from the band. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
