1. A device for treatment of anal fistula, the device comprising:
a hollow wire comprising a first end and a second end opposite to the first end having a second end outer diameter, the hollow wire is operable to be received by a fistula track with both the first and second ends projecting out of the fistula track;
an insert operable to be partially inserted into the first end of the hollow wire and to project out of the first end; and
an applicator operable to be removably arranged on the second end of the hollow wire when the hollow wire is placed in the fistula track;
wherein the applicator is operable to be held for enabling the projected out insert to be inserted into the second end for detachably coupling the first and second ends to form a closed loop around the fistula track;
wherein at least a portion of the applicator is openable, and
wherein the applicator comprises a channel that is operable to removably receive the second end of the hollow wire therein, the channel further forming, when the openable portion is held closed:
a narrow section having a narrow section inner diameter less than the second end outer diameter; and
a broad section extending from the narrow section and having a broad section inner diameter greater than the second end diameter;
such that when the openable portion is held closed on the second end of the hollow wire, the second end of the hollow wire is snugly received by the narrow section and freely received by the broad section for enabling insertion of the projected out insert through the broad section and into the second end while the openable portion is held closed on the second end of the hollow wire.
