Abstract
The present invention is implantation materials comprising an anti-thrombogenic material contained in the surface in contact with blood, of a porous substrate with its voids filled with denatured albumin or a biodegradable polyester. Since they are excellent in anti-thrombogenic property and allow the positive introduction of cells into the implantation materials, they can prevent thrombogenesis for long periods of time. Especially even if they are used as artificial small diameter blood vessels of less than 6 mm in inner diameter, they show excellent patency.
