Retractable Separating Systems and Methods
First Claim
1. A method for separating an object from a patient, comprising:
- providing a tool comprising a sheath having a proximal end and a distal end, and a separating assembly operably coupled to the distal end of the sheath, wherein the separating assembly comprises a tip and a separator having a separating mechanism, and the separating mechanism of the separator is undeployed;
placing the separating assembly near patient tissue that is attached to the object;
rotating the sheath to induce relative rotational movement between the separator and the tip so as to deploy the separating means of the separator; and
applying the deployed separating mechanism to the patient tissue that is attached to the object, so as to separate the tissue from the object.

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 means is deployed, and a second configuration where the separating means is undeployed.

17. A separating system for detaching an object from a patient, comprising:
-
a sheath having 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 separating assembly is adapted to switch between a deployed configuration where a portion of the separating mechanism is exposed and an undeployed configuration where the portion of the separating mechanism is unexposed. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28)

29. A method for detaching an object from a patient, comprising:
-
providing a tool comprising a sheath having a proximal end and a distal end, and a separating assembly coupled with the distal end of the sheath, wherein the separating assembly comprises a tip and a separator having a separating mechanism, and the separating assembly is in an undeployed configuration; placing the separating assembly near patient tissue that is attached to the object; frictionally engaging a contact region of the separating assembly with a site adjacent to or on the patient tissue; rotating the sheath so as to deploy the separating assembly while the contact region remains frictionally engaged with the site adjacent to or on the patient tissue; and applying the separating mechanism to the patient tissue that is attached to the object, so as to separate the tissue from the object. - View Dependent Claims (30, 31)
