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.

Description

RELATED APPLICATION

[0001] This application claims priority to U.S. provisional patent application 61 / 164,344, filed Mar. 27, 2009, the entire disclosure of which is incorporated herein by this reference.FIELD OF THE INVENTION

[0002] The present invention generally relates to medical implants for reconstruction, augmentation and / or wound healing and more specifically relates to such implants including a polymer component and a cellular component.BACKGROUND OF THE INVENTION

[0003] Often following damage such as a surgical incision, skin can benefit from additional support to promote wound healing. This is in part because spontaneous recovery can require a long period of time and pain can continue throughout the repair process.

[0004] Repair of soft tissue defects also is critical following reconstructive and augmentative surgeries. For example, more than 250,000 reconstructive procedures are performed on the breast each year. Women afflicted with breast cancer, congenital defects or damage r...
