    摘要: Described are devices, methods, and systems useful in the treatment of fistulae, and in certain embodiments those having openings extending into the alimentary canal, such as anorectal fistulae. Illustratively, an anorectal fistula can be treated by placing a volumetric construct within the primary opening of the fistula. In certain embodiments, the volumetric construct can include a rolled remodelable material processed to form a substantially unitary body. Advantageous such remodelable materials can include collagenous extracellular matrix materials, such as small intestine submucosa.

    摘要: Described are medical products, systems, and methods for treating fistulae having a primary opening, such as in the alimentary canal. Certain methods of the invention include providing an implantable material including a compliant sheet form biocompatible material, and forcing this sheet form biocompatible material into the primary opening so as to deform the sheet form biocompatible material to conform to and block the primary opening. The biocompatible material preferably comprises a remodelable material, for example, a remodelable extracellular matrix material such as submucosa.

    摘要: Described are stent graft devices and methods for their preparation and use. Expandable stent graft devices of the invention include inner and/or outer coverings uniquely applied and associated with surfaces of the stent. In certain described embodiments, bioremodelable materials such as ECM materials are vacuum pressed onto and/or around elements of a stent in the manufacture of a stent graft device.
