Some aspects of the present invention are directed to unique products and methods for treating fistulae and other passageways and openings in the body. In some preferred forms, an inventive construct will include an elongate graft body that incorporates a plurality of sheet or sheet-like segments. The plurality of sheet or sheet-like segments, in some arrangements, will be stacked in a generally longitudinal direction along the length of the plug body, and optionally, the segments will be received over one or more elongate elements. Elongate elements of this sort can take a variety of forms including a suture, wire, filament, or other relatively thin-bodied elongate member, although in some forms, an elongate element will be or include a somewhat heftier structure such as a biodegradable or non-biodegradable three-dimensional body.

Devices and methods for treating fistulae and other bodily openings and passageways

Described, in certain respects, are unique methods and systems for treating fistulae and other passageways and openings in the body. In some embodiments, treatment will be performed on fistulae that include a passage extending through a subcutaneous wall or wall-like structure. Illustratively, such a passage can extend through a subcutaneous tissue wall that includes, at a minimum, portions of an intestinal wall, and in this regard, such a wall can have a first side that is provided by the luminal side of the intestines and a second subcutaneous side that is provided, for example, by the abluminal side of the intestines and/or by other subcutaneous tissues adhered to this abluminal side. Some inventive products and methods involve sealing off the passage from both sides of the wall, for example, where a sealing element is placed on each side of the wall over an opening to the passage.

Methods and systems for treating complex fistulae

The embodiments described include graft devices for reinforcing patient tissue structures and methods of making and using the graft devices. In certain embodiments the graft devices have a remodelable extracellular matrix material graft body defining a slot and having a portion receivable through the slot to form a closed loop. Such graft devices can be used in encircling reinforcement of patient tissue structures such as anal sphincters or anastomosed vessel segments.
