The Netherlands
Devices for treatment


Current knotted setons used in perianal fistula drainage cause pain and discomfort for patients, leading to complications requiring additional treatment. This is all the more important for people with cryptoglandular fistulae, and particularly those suffering from Crohn’s disease (perianal fistulae), whereby almost half need setons on a semi-permanent basis. Patients returning for treatment due to complications can incur a significant cost to the healthcare system.



Superseton is a smooth, simple and secure solution that prevents unnecessary irritation and discomfort for patients. It features an innovative closure that is secure and flexible, and can be applied manually in seconds with the patented disposable applicator. While the ingenious design offers numerous benefits, it still fits seamlessly with established practice.
