Abstract

The invention is directed to an apparatus, such as a medical device, having a surface coated or covered with a decellularized extracellular matrix or having a component comprising the decellularized extracellular matrix for implantation into a subject, preferably a human. In one embodiment of the invention, a decellularized extracellular matrix is used to form a bodily implant such as a vein, an artery, an esophagus, or a ventricular restraining device. In some embodiments of the invention, the decellularized extracellular matrix is configured to be a time released therapeutic. In another embodiment of the invention, a decellularized extracellular matrix forms an aneurysm treatment device, such as an aneurysm coil, a seal, a pouch, or a filler. In a further embodiment of the invention, decellularized extracellular matrix is used to embolize lesions, tumors, or vessels. Methods for making the tissue regeneration scaffold and methods for manufacturing a coated or covered medical device having a component comprising decellularized extracellular matrix of body tissues are also provided.

Claims
