A fistula treatment kit, comprising:

• at least one tube containing at least four interconnected elongate bioresorbable expansion members;
• a push member configured to push the expansion members out of the tube;
• and
• an expandable occluding member comprising a substantially non-elastic polymer material.

A method of treating a tissue tract, comprising:

• inserting an occluding member into a tissue tract toward an anatomical body space;
• occluding the tissue tract by applying the occluding member against a surface of the body space;
• and
• filling the tissue tract with a first bioresorbable material without pre-coupling the first bioresorbable material to the inserted occluding member.

A tissue tract treatment system, comprising:

• an expandable distal anchor comprising an anchor attachment site and having a delivery configuration with a first cross-sectional area and a deployment configuration with a second cross-sectional area greater than the first cross-sectional area;
• an anchor tether;
• a first delivery tube configured to deliverably retain the expandable distal anchor and the anchor tether;
• and
