Abstract
A treatment system includes an insert that is resiliently deflectable. The tip portion of the insert can be configured to be coupled to the trailing portion of an implant. A guide tube having an internal lumen is configured to permit passage of the tip portion and the body portion of the insert through a guide tube. The guide tube can have a length that is less than that of the insert. Treatment systems include a plurality of inserts, each insert differing from in at least one of length, diameter, and curvature. Treating a patient can include sizing a fistula using an insert.
