Devices and methods for performing procedures on a breast

摘要

A needle is used to mark a tissue area of interest. The needle may have one or more indicators which indicate selected angular orientations relative to the needle. The indicators may also be coupled to anchors which are deployed in the tissue to anchor the needle in the tissue. The needle may be positioned to guide an excisional device to remove tissue.

1. A method of positioning a needle in a patient's breast to mark a tissue area of interest for removing tissue from the patient's breast, the method comprising:
introducing a distal portion of a needle into the patient's breast under visualization; rotating the needle to align a first indicator on a proximal portion of the needle to a first angular position relative to the tissue area of interest; deploying a first anchor on the distal portion of the needle into the breast; removing a stiffener from the needle to render the proximal portion of the needle flexible; advancing a tissue removal device over the needle into the breast; deploying a cutting element on the tissue removal device; and removing tissue from the patient's breast, using the tissue removal device.
