Abstract
The device includes a bar having a longitudinal axis and adapted to be inserted into a fistulous tract. A cutting tool cooperates with the bar such that the cutting tool separates the fistulous tract from the surrounding tissue by coring the fistula.
Claims3
A method for excision of a fistula, which includes a fistulous tract, comprising the steps of:
- providing an excision device having a guide bar and a cutting tool fixed to said guide bar such that there is no relative movement between said guide bar and said cutting tool, a distal end of said guide bar extending beyond a distal end of said cutting tool;
- inserting said distal end of said guide bar into a proximal end of the fistulous tract;
- and
- moving said excision device including said guide bar and said cutting tool as a unitary device relative to the fistulous tract such that said cutting tool separates tissue surrounding the fistulous tract from the fistulous tract.

A method for excision of a fistula, which includes a fistulous tract, comprising the steps of:
- first inserting an accessory bar into the fistulous tract;
- next inserting a sheath over said accessory bar such that a distal portion of said sheath is located at a distal end of the fistulous tract and a proximal end of said sheath is located at a proximal end of the fistulous tract;
- removing said accessory bar from within said sheath;
- providing an excision device having a guide bar and a cutting tool associated with said guide bar;
- introducing a distal end of said guide bar into said proximal end of said sheath;
- advancing said guide bar and said cutting tool fixed to said guide bar as a unitary device toward said distal end of the fistulous tract using said sheath as a guide to thereby core the fistulous tract from surrounding tissue.
