Mentor Clinical Study of the Contour Profile Gel Mammary Prosthesis Cohesive Silicone Gel Breast Implants |
Objective:
Demonstrate safety and effectiveness of Mentor's Contour Profile Gel (CPG) Mammary Prosthesis in women who are undergoing primary augmentation, primary reconstruction, or revision.
Design:
- Multicenter
- Non-masked, open label
- Two year data submitted to FDA as part of Pre-Market Application
- Follwing FDA approval, follow up data collected: Rheumatic Disease Diagnosis, QoLs, silent rupture with MRI, and Adverse Events up to 10 years annually
Population:
- Total subject population 950
- Population reflective of the target subject population with respect to indication
Enrollment numbers by indication:
Augmentation: 570
Reconstruction: 190
Total number of Investigators: up to 60
Total number of surgical sites: up to 100
Study Device: Mentor Siltex ® Contour Profile Gel Mammary Prosthesis
Inclusion Criteria:
- Subject is Genetic female and is at least 18 years old
- A candidate for:
- Primary breast augmentation (for general breast enlargement)
- Primary breast reconstruction (for cancer, trauma, surgical loss of breast or congenital deformity)
- Revision surgery (previous augmentation or reconstruction with silicone-filled or saline-filled implants)
- Signs the Informed Consent
- Agrees to return device to Mentor if explant necessary
- Agrees to comply with follow-up procedures, including returning for all follow-up visits
Exclusion Criteria:
- Subject is pregnant
- Has nursed a child within three months of study enrollment
- Been implanted with any silicone implant other than breast implants
- Confirmed diagnosis of rheumatic disease
- Currently has a condition that could compromise or complicate wound healing (except reconstruction subjects)
- Subject in Augmentation cohort and has diagnosis of active cancer of any type, except low-grade non-metastasizing skin cancer
- Infection or abscess anywhere in the body
- Demonstrates tissue characteristics which are clinically incompatible with implant (e.g. tissue damage resulting from radiation, inadequate tissue, or compromised vascularity)
- Possesses any condition, or is under treatment for any condition which, in the opinion of the investigator and/or consulting physicians(s), may constitute an unwarranted surgical risk.
- Anatomic or physiologic abnormality which could lead to significant postoperative adverse events
- Demonstrates characteristics that are unrealistic/unreasonable with the risks involved with the surgical procedure
- Premalignant breast disease without a subcutaneous mastectomy.
- Untreated or inappropriately treated breast malignancy, without mastectomy
- Are HIV positive
- Work for Mentor or the study doctor or are directly-related to anyone that works for Mentor or the study doctor
- Implanted metal or metal devices, history of claustrophobia or other condition that would make a MRI scan prohibitive

A - At 1, 2, 4, 6, 8, and 10 years.
B - Rosenberg Self Esteem Scale, SF-36, Body Esteem Scale, Breast Evaluation Questionnaire.
C - Required for randomly selected 400 of subjects.
D - Including secondary procedures and reimplantations upon occurrence, whether noted at a schedule or interim visit.
E - At 1, 2, and 3 years.
Safety Endpoint:
Incidence, severity, method of resolution, and duration for all adverse events on a per implant and per subject basis
Effectiveness Endpoints:
Primary - Changes in chest circumference and bra and cup size (may not be applicable to reconstruction subjects)
Secondary - Changes in Quality of Life results
