Brief Summary:
The purpose of this study is to provide prospective evidence that the use of Magseed/Sentimag in marking axillary lymph nodes and guiding surgical localization in patients with breast cancer following neo-adjuvant chemotherapy (NAC) is effective.

Condition or disease Intervention/treatment Phase
Breast Cancer Axillary Lymph Nodes Device: Magseed Marker Not Applicable

Detailed Description:
This is a post-market, prospective, open-label, single arm study of Magseed and Sentimag in patients with breast cancer with biopsy-proven axillary node metastases who had a clip placed to mark the metastatic node and are having that clipped node selectively removed at surgery following neo-adjuvant chemotherapy (NAC). Subjects will have the Magseed placed to mark axillary lymph nodes with biopsy-proven metastasis under ultrasound guidance before initiating NAC. After completion of NAC, the Magseed will be localized using the Sentimag system during surgery and removed with the targeted lymph node.

Arm Intervention/treatment
Experimental: Magseed marker
Magseed marker deployed percutaneously, prior to patient undergoing neo-adjuvant chemotherapy (NAC), under ultrasound guidance to mark a lymph node intended for selective surgical removal post NAC.
Device: Magseed Marker
Implantable Magseed marker for marking lesions in soft tissue, detected using the Sentimag handheld probe.

Primary Outcome Measures :
  1. Retrieval rate of clipped node and Magseed in the excised specimen [ Time Frame: Time of surgery ]
    The retrieval rate of the clipped node and Magseed in the excised specimen. This is defined as the number of subjects in whom the clipped node and Magseed are retrieved in a single excised specimen divided by the total number of subjects.

Secondary Outcome Measures :
  1. Rates of device and serious device-related events [ Time Frame: Up to 42 days post-surgery ]
    Rates of device-related adverse events and serious device-related adverse events

  2. Radiologic rated ease of Magseed placement [ Time Frame: Time of Magseed marker placement ]
    5 point Likert scale, very easy = 5, very difficult = 1

  3. Radiologic placement accuracy [ Time Frame: Between completion of NAC time of surgery ]
    Success rate of seed placement (placement accuracy)

  4. Radiologic seed position [ Time Frame: After completion of NAC ]
    Success rate of maintained seed position at the completion of NAC

  5. Surgical nodes localized [ Time Frame: Time of surgery ]
    Number of nodes retrieved within the surgical specimen containing the Magseed

  6. Ease of surgical localization [ Time Frame: Time of surgery ]
    5 point Likert scalevery easy = 5, very difficult = 1
