Abstract
Described are methods and systems for treating fistulae and other passageways and openings in the body. In certain aspects, an anchored suture is provided that extends from at or near a first fistula opening and through a fistula tract toward a second fistula opening. Various modes of anchoring may be used in this regard including, in some modes, having the suture extend from a deployed anchoring member positioned in and/or around the first opening. The anchored suture, which has a more slender cross sectional dimension relative to the fistula tract through which it extends, is capable of receiving an optional fill substance therealong in the tract. A fill substance can be or include a variety of biodegradable and/or non-biodegradable objects and materials including flowable and non-flowable materials.
