Abstract: Disclosed are tissue implant materials for use in grafting procedures. More particularly non-vascular tissue for use as vascular graft material and a method of vascular grafting using non-vascular tissue is disclosed. The tissue is preferably autologous relative to the recipient of the graft and is conveniently prepared around or on a molding support inserted into a body cavity of the intended recipient of the graft. These tissues and methods are particularly useful in the treatment or prophylaxis of diseased or damaged blood vessels such as in atherosclerosis.
