Patent ID: 8439942

Claim:
A method for achieving full occlusion at a site in the body of a patient, comprising: providing an implantable occlusion device for delivery to the site, the occlusion device comprising a remodelable collagenous biomaterial harvested from an animal tissue source and retaining at least one biotropic agent from the animal tissue source, the biotropic agent selected from a proteoglycan, a growth factor, a glycoprotein and a glycosaminoglycan; and delivering the occlusion device to the site with the occlusion device remaining at the site for a period of time sufficient for the remodelable collagenous biomaterial to promote cellular invasion and ingrowth into the occlusion device and to become remodeled with tissue of the patient so that an all-natural, remodeled tissue blockage is generated at the site and remains at the site fully occluding the site.
