1. A method of treating a perianal fistula with a helical implant system having a driver and a helical implant, the helical implant having a proximal end and a distal end, the perianal fistula having an internal opening from a rectum, an external opening in an external surface of a buttocks, a fistula tract extending between the internal opening and the external opening, and fistula tissue surrounding the fistula tract, the method including:
centering the distal end of the helical implant in a concentric fashion to the internal opening with a centering feature of the helical implant system and a seton or a suture connected to the centering feature, and
advancing the helical implant into tissue surrounding the internal opening to compress the fistula tissue via the helical implant.
