Eligibility Criteria
You may qualify if:
- People with moderate to severe functional constipation according to Rome IV criteria.
- People who agree to use appropriate medical methods of contraception from the time they sign the ICF until the end of the treatment period (excluding women in a medical sterilization status).
- People who had a colonoscopy within three years before screening and negative results, or their colonoscopy results are judged by the investigator as mild anomalies, but the cause of their constipation cannot be explained. If the colonoscopy report is unavailable, the study physician will determine if a colonoscopy is needed. If the subjects undergo a colonoscopy after signing the ICF, they will not enter the treatment period until their BMs return to the baseline level.
- People had colonic polyps and a polypectomy (except for endoscopic submucosal dissection (ESD)): Those with a polyp ≤1 cm can be enrolled one month after the polypectomy; Those with a polyp \>1 cm can be enrolled three months after the polypectomy.
- People who consent to participate in this trial and can communicate with the investigator and can understand and comply with the relevant procedures and requirements during the study (including completing study questionnaires on time, being treated and visited as scheduled, and undergoing relevant examinations), and voluntarily sign the ICF.
You may not qualify if:
- People who are not eligible for surgery or refuse to undergo any abdominal surgery.
- People with known or suspected gastrointestinal obstruction, stenosis, diverticulum, bleeding, malformation, and fistula.
- People allergic to polymeric materials.
- People implanted with cardiac pacemakers and using gastrointestinal pacemakers.
- People with abdominal aortic aneurysms, gastrointestinal vascular lesions, ulcers, and lesions with bleeding tendencies.
- People with dysphagia.
- Pregnant women or women with pregnancy plans in the next year.
- People with severe depression and anxiety and severe acute gastrointestinal lesions.
- People who had gastrointestinal surgery or a history of surgery that changed the structure of the gastrointestinal tract (except for appendectomy) or people who underwent gastrointestinal ESD in the past three months.
- People with severe hemorrhoids (patients with grade III-IV hemorrhoids according to the Clinical Practice Guidelines for the Management of Hemorrhoids of the American Society of Colon and Rectal Surgeons).
- People who plan to undergo MRI in the near future.
- People with other conditions, so the investigator considers them not eligible for this study.
