Reconstructing non-cartilage structural defects
First Claim
1. A method for providing structural support to a patient in an area of a non-cartilage structural defect comprising the steps of:
- a) providing a polymeric matrix shaped in the form of a desired support member;
b) depositing dissociated cartilage forming cells on and in said matrix to form a matrix/cell construct; and
c) implanting said matrix/cell construct in said patient at a site of a non-cartilage structural defect in need of structural support, wherein said construct forms a cartilaginous structural member having controlled biomechanical properties providing the required structural support in the area of said non-cartilage structural defect.

Abstract
A cartilaginous structural member (CSM) for use in penile reconstruction, for the correction of developmental defects, postoperative reconstruction, and for reconstructive preprosthetic surgery. The cartilaginous structural member (CSM) comprise of live cells seeded onto pre-formed shaped structure which may be biodegradable. The live cells may comprise chondrocyte and the cartilaginous structural member (CSM) for use in reconstructive surgery may be constructed of polyglycolic acid. The implant structure is applicable to use for the regeneration and reconstruction or augmentation of semirigid members of the body such as the penis, nose, ear and locations which naturally has cartilage. Further, the cartilaginous structural member (CSM) may be used in plastic surgery such as, for example, breast augmentation or pectoral augmentation. The cartilaginous structural member (CSM) may be a composite cartilaginous structural member (CSM) comprising additional anchoring and strengthening elements for anchoring or changing the structural strength of said composite cartilaginous structural member (CSM).
