Abstract
An easy-to-produce and mechanically strong tube of an implantable submucosal tissue has been developed which is manufactured in any desired length, wall thickness, or diameter. The construct produced by the method of the invention may be used as grafts for arteries, veins, ureters, urethras, shunts, or in any application where a compliant, tissue-compatible tube is needed. The manufacture of the submucosal tissue prosthesis generally involves wrapping a first sheet of submucosal tissue (,) and a second sheet of submucosal tissue (,) around a mandrel (,), wherein the first end (,) and the second opposite end (,) of the second sheet of submucosal tissue (,) are sutured together with sutures (,). The submucosal tissue is compressed and dried on the mandrel (,) before removing the construct by pulling on a first end (,) and a second end (,) of a water permeable tape to unwind the tape and thus release the construct for eventual use.
