Fistula treatment devices and related methods

摘要: Disclosed herein are implantable fistula treatment devices and related methods. In some embodiments, a distal anchor for an device may comprise suture plurality of foldable members including at least distal-most member proximal-most member. The distal- most attachment structure. first average dimension substantially parallel to the longitudinal axis suture, second orthogonal dimension, third dimensions. be no greater than 30% configured couple surface body lumen opening fistula. also occlude slide along attached proximal dimensions, where 10%
