    摘要: 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 (60) and a second sheet of submucosal tissue (70) around a mandrel (50), wherein the first end (74) and the second opposite end (76) of the second sheet of submucosal tissue (70) are sutured together with sutures (78). The submucosal tissue is compressed and dried on the mandrel (50) before removing the construct by pulling on a first end (54) and a second end (56) of a water permeable tape to unwind the tape and thus release the construct for eventual use.

    摘要: Multi-laminar tissue graft constructs, pseudoisotropic graft constructs and a method of preparing such constructs are described. Multi-laminar tissue graft constructs are prepared by fusing partially overlapped strips of submucosa tissue into a unitary graft construct by compressing the tissue under dehydrating conditions. Pseudoisotropic tissue graft constructs are prepared by overlapping a first strip of submucosa tissue with at least two strips of submucosa tissue orientated so that the longitudinal axis of each strip formts an angle of about 180.degree./N with the longitudinal axes of at least two other strips of submucosal tissue.

    摘要: Described are medical devices useful for applying a bolster material to a surgical fastening device such as a stapler, and related methods of manufacture and use. The devices include an applicator element for receipt between arms of the stapler, and a bolster material, desirably a remodelable extracellular matrix material, coupled to the applicator element. In certain embodiments, the bolster material is held by the applicator element, for example having at least a portion looped around or received through or over a portion of the applicator element. Also described are unique implantable materials including coatings of dried, reversible adhesive.
