Sphincter-sparing techniques for closing anal or rectovaginal fistulas offer your patients a simple solution to painful and embarrassing symptoms. Biodesign communicates with the patient’s body, signaling surrounding cells to grow across the scaffold. The result is fully remodeled, vascularized tissue and complete fistula closure without muscle damage that can lead to incontinence. Patients can return to normal life, free from discomfort and drainage.
