First Claim
Patent Images
1. A method of positioning a localizing wire in a tissue mass, with the localizing wire comprising a thread and an anchor coupled to the thread, the method comprising:
- inserting the localizing wire into the tissue mass such that the anchor is received within the tissue mass and a portion of the thread extends beyond the exterior of the tissue mass; and
laying the external portion of the thread such that it is substantially flat against the exterior of the tissue mass.

Abstract
A localizing wire comprising an anchor portion that can change shape from a collapsed shape to an expanded shape and thereby anchor within a tissue mass. A localizing wire having an exterior portion that can lie flat against the tissue mass. A localizing wire that can be repositioned or withdrawn without the need for the reinsertion of an introducer.

10. A method of implanting and removing a localizing wire having a reconfigurable anchor into a tissue mass, comprising:
-
inserting the localizing wire into the tissue mass;
configuring the anchor into an anchoring configuration where the anchor anchors the localizing wire in the tissue mass;
reconfiguring the anchor from the anchoring configuration to a release configuration, where the anchor does not anchor the localizing wire in the tissue mass; and
withdrawing the localizing wire with the anchor in the release configuration from the tissue mass. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27)

28. A method of marking a lesion in a tissue mass, the method comprising:
-
installing a localizing wire into a tube having at least one lumen, the localizing wire comprising a localizing thread and a localizing anchor having a collapsed shape delineating a first area in the at least one lumen and an expanded shape delineating a second area greater than the first area outside the at least one lumen;
inserting the tube into the tissue;
moving one of the localizing wire and the tube to place the localizing anchor outside the at least one lumen at a first selected location relative to the lesion so that the localizing anchor expands from the first to the second shape to exert an expansive force against the tissue mass. - View Dependent Claims (29, 30, 31, 32, 33, 34, 35, 36, 37, 38)

39. A method of marking a lesion in a tissue mass, the method comprising:
-
providing a localizing wire and a tube having at least one lumen, the localizing wire comprising a localizing thread and a localizing anchor having a collapsed shape delineating a first area when the localizing anchor is in the at least one lumen and an expanded shape delineating a second area when the localizing anchor is outside the at least one lumen;
inserting the tube into the tissue mass;
moving one of the localizing wire and the tube to place the localizing anchor outside the at least one lumen at a first selected location relative to the lesion; and
exerting an expansive force by the localizing anchor against the tissue mass at the selected location relative to the lesion when the localizing anchor transitions from the collapsed shape to the expanded shape. - View Dependent Claims (40, 41, 42, 43, 44, 45, 46)
