Abstract

A device for the treatment of anal fistula-in-ano and complex fistula-in-ano includes a balloon inflation/deflation tube, a suction/drainage tube, a scooping tube, that is disposed between the balloon inflation/deflation tube and the suction/drainage tube, a diaphragm that is disposed across the balloon inflation/deflation tube and the suction/drainage tube, and an irrigation/drainage path that is disposed between a balloon and a plurality of spikes. The balloon is disposed at an end of the balloon inflation/deflation tube.

Claims (13)

1. A device for the treatment of anal fistula-in-ano and complex fistula-in-ano, comprising:

a balloon inflation or deflation tube that is configured to inflate or deflate a balloon that is disposed at an end of the balloon inflation or deflation tube, said balloon configured to create a barrier between an anal canal and a fistula of a patient;

a suction or drainage tube that is configured to drain debris from an internal wound of the fistula and intersphincteric space;

a scooping tube through which the internal wound of the fistula is scooped and debridement is carried out, said scooping tube being disposed adjacent to the balloon inflation or deflation tube and also adjacent to the suction or drainage tube;

a diaphragm that holds the device in place and keeps a neck of the fistula wide for drainage to prevent premature closure, said diaphragm being disposed across the balloon inflation or deflation tube and the suction or drainage tube; and

an irrigation or drainage path disposed on an outer surface of the balloon, said irrigation or drainage path facilitating irrigation of an abscess wall; and

a plurality of spikes disposed on an external surface of said irrigation or drainage path that facilitates adhesion of the balloon inflation or deflation tube and the suction or drainage tube to a cavity.

2. The device for the treatment of anal fistula-in-ano and complex fistula-in-ano as claimed in claim 1 , wherein a length of the balloon inflation or deflation tube ranges between 5 cm and 25 cm.

3. The device for the treatment of anal fistula-in-ano and complex fistula-in-ano as claimed in claim 1 , wherein a length of the scooping tube ranges between 5 cm and 25 cm.

4. The device for the treatment of anal fistula-in-ano and complex fistula-in-ano as claimed in claim 1 , wherein a length of the suction or drainage tube ranges between 5 cm and 25 cm.

5. The device for the treatment of anal fistula-in-ano and complex fistula-in-ano as claimed in claim 1 , wherein a length of the diaphragm ranges between 1 cm and 5 cm.

6. The device for the treatment of anal fistula-in-ano and complex fistula-in-ano as claimed in claim 1 , wherein an expansion capacity of the balloon ranges between 1 mL and 7 mL.

7. The device for the treatment of anal fistula-in-ano and complex fistula-in-ano as claimed in claim 1 , wherein the balloon is configured to be inflated by a sterile, water-filled syringe.
