  • Patent number: 9993235
    Abstract: Disclosed herein is a non-vascular fistula treatment system. The system may include a collapsible member, at least one tether, and a bioresorbable material. The collapsible member may be configured for positioning through a fistula tract and may comprise first and second disc members. The outer perimeter of the second disc member may be larger than the outer perimeter of the first disc member, and the first disc member may comprise a tether attachment structure. The at least one tether may be attached to the tether attachment structure. The bioresorbable material may be configured for placement in the fistula tract and may comprise a coupling structure configured to couple to the at least one tether. The second disc member may be configured to seal to a surface of a body lumen at a distal opening of the fistula tract and occlude the fistula tract at the distal opening.
