Primary Outcome Measures:
  • The primary objective is to develop an injection technique for placement of the implant posterior to the mammary gland. This will be documented through MRI 1-5 days after the injection and evaluated by the Expert Group 6 weeks after treatment. [ Designated as safety issue: No ]
    Inclusion was made in steps, each step incl. treatment of 2 subjects at each of the 2 sites (1 group). The subjects were followed-up with MRI 1-5 days after the injection. Before the next group of 4 subjects were treated, the Expert Group evaluated the 6-week follow-up results of the previous group. The injection procedure was, if necessary, changed in accordance with specifically pre-defined parameters.The aim of the step-wise inclusion was to refine the injection procedure through implant placement assessment, and to evaluate safety and the esthetic results prior to treating the next group.

Secondary Outcome Measures:
  • Assess the safety at 6 weeks through physical examination, reported adverse events (AEs) and Adverse Experiences reported in a diary during 2 weeks post treatment. [ Time Frame: 2 weeks ] [ Designated as safety issue: Yes ]
  • evaluate esthetic improvement at 6 weeks as judged by the investigator using GEIS [ Time Frame: 6 weeks ] [ Designated as safety issue: No ]
  • evaluate pain experienced during injection under local anesthesia [ Designated as safety issue: No ]
  • assess if inflammatory response is elicited by the implant, using blood sample analysis and body temperature (first 8 treated patients only) [ Designated as safety issue: Yes ]
  • assess if the gel can be detected and delineated from surrounding tissues by mammography as evaluated and commented by the radiologist 12 months after treatment. [ Designated as safety issue: Yes ]
  • assess the safety as documented by physical examination and by AEs reported up to 24 months. [ Time Frame: 24 months ] [ Designated as safety issue: Yes ]
  • evaluate, at 12 months, in 4 subjects, any implant damage or displacement caused by compression of the breast in conjunction with mammographic investigation using MRI [ Time Frame: 12 months ] [ Designated as safety issue: Yes ]
  • evaluate the esthetic improvement as judged by an independent evaluator, by the investigator and by the subject using GEIS, up to 24 months. [ Time Frame: 24 months ] [ Designated as safety issue: No ]
  • evaluate, up to 24 months, the subjects satisfaction with her breast and general appearance using a questionnaire. [ Time Frame: 24 months ] [ Designated as safety issue: No ]
