What is it? The MemoryShape Breast Implant is a silicone shell filled with clear silicone gel. The silicone gel is firmer (more cohesive) than Mentor’s previously approved implant (P030053). The MemoryShape Breast Implant is available in a variety of sizes.
How does it work? The MemoryShape Breast Implant is intended to make the breast larger (breast augmentation) or to restore or replace breast tissue (breast reconstruction). It is surgically implanted beneath the breast tissue, either on top of the chest muscle or underneath part or all of the chest muscle.
When is it used? The Mentor MemoryShape Breast Implants are indicated for females for the following uses (procedures):
- Breast augmentation for women at least 22 years old. Breast augmentation includes primary breast augmentation to increase the breast size, as well as revision surgery to correct or improve the result of a primary breast augmentation surgery.
- Breast Reconstruction. Breast reconstruction includes primary reconstruction to replace breast tissue that has been removed due to cancer or trauma or that has failed to develop properly due to a severe breast abnormality. Breast reconstruction also includes revision surgery to correct or improve the results of a primary breast reconstruction surgery.
What will it accomplish? The implant increases the size of the breast. A majority of subjects in the clinical study reported favorable satisfaction and Quality of Life.
Common adverse effects identified in the clinical study include:
- Uneven appearance (asymmetry)
- Breast pain
- Breast sensation changes
- Tightening of the area around the implant (capsular contracture)
