Patent ID: 8414602

Claim:
A method for marking a breast cyst or a breast biopsy site, comprising the steps of: a. inserting a needle into the breast cyst or the breast biopsy site; b. removing fluid from the breast cyst or tissue from the breast biopsy site; c. inserting a delivery device, that includes a clip, into the needle and the cyst or the breast biopsy site; d. pushing an actuator and a driver of the delivery device along an inside portion of the delivery device so that the clip travels down the inside portion of the delivery device; and e. expelling the clip along a ramp located in a hole of the delivery device that is in alignment with a hole in the needle, resulting in the insertion of the clip through the hole in the delivery device, then the hole in the needle, and then into the breast cyst or the breast biopsy site to mark the same; wherein the clip comprises: i) a first arcuate portion having a first end located at a first end of the clip and a second end located at a second end of the clip; ii) a second arcuate portion having a first end located at the first end of the clip and a second end located at the second end of the clip, the second arcuate portion being coplanar with the first arcuate portion; and iii) an apex disposed along a clip axis defining where the first arcuate portion and the second arcuate portion adjoin and converge, the first arcuate portion and the second arcuate portion fits within a delivery tube of the delivery device; wherein the first ends of the first arcuate portion and the second arcuate portion project in a direction outward relative to the clip axis, the second ends of the first arcuate portion and the second arcuate portion project in a direction outward relative to the clip axis in both a pre-deployment state and a post-deployment state, and the clip does not form a spiral configuration, and thereby substantially prevents migration of the deployed clip within the breast.
