Summary

The clinical trial is testing the use of a novel method to grow new tissue within the breast injecting fat tissue harvested from patient's own fat deposits. A scaffold implant acts as a resorbable frame to support this growth of cells. The scaffold will be resorbed within at least 3 years. The main assumption of this clinical trial is that the method used is safe and effective for treatment of women requiring a silicone implant and /or correction of breast defect and/or deformity. The other assumption is that this method is applicable to a wider range of tissue defects, such as breast reconstruction after breast tissue removal. The new method is called '3D printed scaffold-based soft tissue regeneration', and uses a combination of own fat cells (called adipocytes) with a 3D printed scaffold to support soft tissue regeneration using the natural healing processes in their body. This substance is resorbable and is similar to the substance used for sutures and stitches that are dissolvable or resorbable in the body. The substance used for the scaffold is already Therapeutic Goods Administration (TGA) approved for bone reconstruction of the skull. The implanted scaffold degrades over time, leaving the their own tissue in its place. The combination of scaffold implantation and their own fat cells is the novel method in this trial. Conventional liposuction techniques are used from another site on the patients body to harvest their fat cells.

Conditions

  • Breast Implant Revision
  • Congenital Breast Defect Correction

Interventions

DEVICE

Surgical implantation of the PCL Breast scaffold with autologous fat grafting

Single shot of prophylactic perioperative antibiotics is given to the patient. A suitable incision is made to provide access followed by mobilisation of the breast gland.If present, the silicone implant is removed and capsulectomy performed. The implant pocket shall be rinsed with saline or antiseptic and a surgical drain shall be placed in the pocket at the discretion of the PI. The PCL Breast scaffold shall be inserted into the pocket and fixed using 2 to 4 sutures. The incision is closed. Liposuction is performed from another area of the body and lipofilling is performed within the breast scaffold. Sterile bandaging is applied and a daily wound revision is performed whilst an inpatient. A prophylactic antibiotic shall be administered to the patient.The patients shall be hospitalized overnight for clinical observation.
