Brief Summary:
This study evaluates the safety and effectiveness of the da Vinci Surgical Systems in prophylactic Nipple Sparing Mastectomy procedures.

Condition or disease Intervention/treatment Phase
Nipple Sparing Mastectomy Device: Nipple-Sparing Mastectomy Not Applicable

Detailed Description:

Surgical management for breast cancer and risk-reducing techniques have evolved from radical mastectomy to other techniques such as nipple and skin sparing procedures. Nipple-sparing mastectomy (NSM) with reconstruction technology offers the opportunity to preserve the shape of both the breast and the nipple-areola complex.

This study will evaluate the safety and effectiveness of the da Vinci Surgical Systems in NSM procedures.

Nipple-sparing mastectomy using da Vinci Surgical Systems.

Primary Outcome Measures :
  1. Primary Effectiveness: No conversions to open NSM [ Time Frame: Assessed during surgery ]
    Conversion is defined as conversion of da Vinci robotic-assisted surgery to open surgery

  2. Primary Safety: Incidence of adverse events [ Time Frame: Assessed during surgery to 42 days after surgery ]
    Incidence of intraoperative and post-operative procedure and device-related adverse events

Other Outcome Measures:
  1. Incidence of breast cancer [ Time Frame: Annual through 5 year post-operatively ]
    Occurrence and recurrence of breast cancer

  2. Patient reported outcomes [ Time Frame: Pre-operatively, post-operatively at 42 days, annually through 5 years ]

  3. Long-term safety: incidence of adverse events [ Time Frame: Annually through 5 years post-operatively ]
    Incidence of breast procedure-related adverse events during long-term follow up
