Details and patient eligibility


This is a Phase IV, multicenter, open label, non-randomized comparative group study to assess the safety and performance of the OrbiSymm system in subjects referred to contra lateral breast symmetrization involving a breast reduction following breast reconstruction post-mastectomy.

Full description

The device has the CE Mark and will be used in the indication for which it is approved. Up to 60 patients will be assigned to the study (up to 30 patients for Orbix procedure, and up to 30 patients without Orbix procedure (only routine reduction/symmetrisation). Patients will return to the clinic for follow-up at 1, 3, 6, 12 & 24 months (last visit will be optional).


60 estimated patients




18 to 65 years old


No Healthy Volunteers

Inclusion criteria

  • Female subject between the age of 20 and 65 years old
  • Underwent breast reconstruction following unilateral mastectomy and referred to contra lateral symmetrisation procedure that requires reduction of at least 150gr (clarification: the procedure of reconstruction and symmetrisation may be performed simultaneously).
  • Breast size ≥D
  • BMI≤ 32

Exclusion criteria

  • Pregnant or lactating woman.
  • Subject with history of surgical procedures involving the ribs and rib cage.

  • Subject suffering from reconstruction failure, skin necrosis or implant infection.
  • Subject with diagnosed or suspected auto-immune disease.
  • Subject with pathologies that affect blood coagulation, immune system or any treatment interfering with them.
  • Subject with lesions due to radiation, ulceration, vascular anomalies or history of circulatory disorder.
  • Subject suffering from a progressive fibrocystic disease, considered to be pre-cancerous, without mastectomy.
  • Subject with concurrent diseases determined by the surgeon to pose unduly high risk of surgical and/or postoperative complications such as obesity, smoking, diabetes, autoimmune disease, coagulopathy, chronic lung or severe cardiovascular disease.
  • Use of drugs that might result in high surgical risk and/or significant postoperative complication, including drugs that would interfere with blood clotting.
  • Psychological instability, inappropriate attitude or motivation.
  • Subject participating or that has participated until one month prior to planned procedure, in another investigational study.
