Abstract
Disclosed herein are polyurethane polymer matrices with a porosity of from about 20 microns to about 90 microns that are useful in promoting closure and protection of incision sites; supporting the lower pole position of breast implants; and providing a partial or complete covering of breast implants to provide a beneficial interface with host tissue and to reduce the potential for malpositioning or capsular contracture. The disclosed matrices can be seeded with mammalian cells.
Claims24
A medical implant comprising:
- a breast prosthesis;
- and
- a covering on said breast prosthesis, the covering comprising silk;
- the covering providing a beneficial interface between the breast prosthesis and host tissue and reducing the potential for malpositioning or capsular contracture.
A medical implant useful for reconstruction or augmentation, the implant comprising:
- a fluid-filled prosthesis;
- and
- a covering on said prosthesis, the covering comprising silk;
- the covering providing a beneficial interface between the prosthesis and host tissue.
A breast implant comprising:
- a saline or silicone filled breast prosthesis;
- and
- a covering on said breast prosthesis in a wrap like configuration, the covering comprising woven silk;
- the covering providing a beneficial interface between the breast prosthesis and host tissue and reducing the potential for malpositioning or capsular contracture;
- the covering being porous and having a pore size diameter of from about 10 to about 1000 microns.
