Tissue tagging device
First Claim
1. A tagging device for identifying a particular location within a mass of body tissue comprising:
- an elongated tube having a proximal end and a distal end;
an anchor releasably positioned within the distal end of the elongated tube;
an elongated member having a first end connected to a central portion of the anchor;
a tension member attached to said elongated tube, said tension member being adapted to hold the elongated member in tension relative to the elongated tube; and
a plunger operably engageable with the anchor to move the anchor from a first position within the elongated tube to a second position ejected from the elongated tube;
wherein the plunger and anchor are configured to rotate the anchor as the anchor moves between the first and second positions.

Abstract
A tagging device for marking the location of lesions within the body prior to a surgical procedure such as excision or biopsy. The device includes an elongated tube having one end supported on a housing and a second end extending distally therefrom. An anchor is positioned within the distal end of the elongated tube and has an elongated member extending proximally therefrom. An actuation assembly including a plunger is movable within the tube to engage and push the anchor from the distal end of the tube. The anchor and the actuation assembly are positioned and configured such that the anchor is pivoted from a position parallel to the longitudinal axis of the tube to a position perpendicular to the longitudinal axis of the tube as it as being pushed from the tube.

14. A tagging device for identifying a particular location within a mass of body tissue comprising:
- an elongated tube having a proximal end and a distal end;
an anchor releasably positioned within the distal end of the elongated tube;
an elongated member having a first end connected to a central portion of the anchor; and
a plunger which defines a hollow tube slidably positioned within the elongated tube, a second end of the elongated member being positioned within the hollow tube, the plunger being operably engageable with the anchor to move the anchor from a first position within the elongated tube to a second position ejected from the elongated tube, the distal end of the hollow tube and of the elongated tube having a longitudinal slot dimensioned to permit passage of the elongated member during movement of the anchor between the first and second positions; and
wherein the plunger and anchor are configured to rotate the anchor continuously as the anchor moves between the first and second positions.
- an elongated tube having a proximal end and a distal end;

15. A tagging device comprising:
-
an elongated tube having a proximal and a distal end; an anchor positioned within the elongated tube; an elongated member extending parallel to and external of the elongated tube, the elongated member having a distal end connected to the anchor and a proximal end connected to the proximal end of the elongated tube. a plunger movably positioned within the elongated tube from a retracted position to an extended position to engage and move the anchor from a first position within the elongated tube to a second position outside the elongated tube; and wherein the elongated member is connected to the anchor a position to cause the anchor to continuously rotate during movement between the first and second positions.

16. A tagging device comprising:
-
an elongated tube having a proximal end and a distal end; an elongated anchor positioned within the elongated tube and having a central portion and a body sloping away from the central portion to first and second ends thereof; an elongated member having a distal end connected to the central portion of the anchor and a proximal end extending within the elongated tube; a plunger positioned within the elongated tube and being movable between retracted and extended positions to engage the second end of the anchor and move the anchor from a first position within the elongated tube wherein the anchor is disposed in a first orientation such that one of the ends of the anchor is distal of the central portion and the other end is proximal of the central portion, to a second position outside the elongated tube; and wherein the second end of the anchor is configured to cause rotation of the anchor during movement between the first and second positions. - View Dependent Claims (17)
