Eligibility Criteria:
Inclusion Criteria:~1. Crohn's disease diagnosis for at least 3 months, confirmed by clinical, biochemical, and endoscopic evaluations.~2. Patients with CD involving the small bowel and / or colon with active symptoms with Crohn's Disease Activity Index (CDAI) \> 220 despite at least one conventional therapy (corticosteroids and/or immunosuppressives) with a stable dose will be included.~3. Elevated Fecal calprotectin ≥ 200 micro g/g within the past 4 weeks prior to enrollment~4. If on corticosteroids, the dose must be stable and ≤ 20mg/day prednisone or equivalent for at least 14 days before entry into study.~5. If on background immunosuppressive treatment the dose must be stable with the following parameters:~6. 56 days (8 weeks) for Immunomodulators (methotrexate, 6-MP, Azathioprine) and small molecules (upadacitinib)~7. 112 84 days (16 12 weeks) for biologics (Infliximab, Adalimumab, Vedolizumab, Ustekinumab, another biologic Risankizumab)~8. Clinical laboratory evaluations (including a chemistry panel, complete blood count \[CBC\], and urinalysis \[UA\]) within the reference range for the test laboratory, unless a typical consequence of CD or deemed not clinically significant by the Investigator.~9. Colonoscopy within the previous 1 year with no evidence of colonic dysplasia or cancer.~10. Able and willing to give written informed consent and comply with the requirements of the study protocol.~Exclusion Criteria:~1. Expectation to increase corticosteroids and/or immunosuppressive treatment~2. Presence of bowel stricture with pre-stenotic dilatation~3. Presence of intra-abdominal or perirectal abscess~4. Crohn's Disease Activity Index (CDAI) \< 220~5. Fistula with clinical or radiological evidence of abscess~6. Perianal CD with or without rectal involvement~7. Ileostomy, colostomy, enteral or parenteral feeding~8. Short gut syndrome.~9. Clinical condition medically or surgically unstable that, at the discretion of the investigator would not be compatible with the patient's participation in the study~10. Any malignant neoplasia, in the year prior to screening ,except for nonmelanoma skin cancer.~11. Active treatment with antibiotics~12. Presence of active intestinal infection or documented infection by stool PCR or culture analysis in the previous 6 weeks~13. Continuous treatment with an anti-cholinergic medication, including over the counter medications.~14. Implantable electronic devices such as pacemakers, defibrillators, hearing aids, cochlear implants or deep brain stimulators.~15. Current tobacco or nicotine user within the past 4 weeks (to limit potential confounding effects of exposure to nicotine)~16. Bowel resection surgery within past 90 days prior to study enrollment and on no conventional IBD therapy, or planned surgery within the course of the study~18. Participation in any other Investigational drug and/or treatment currently or planned during the length of the study 19. Any condition which, in the opinion of the investigator, would jeopardize the subject's safety following exposure to a study intervention 20. Pregnancy or Lactation 21. Comorbid disease with high likelihood of requiring corticosteroid use 22. Inability to comply with study and follow-up procedures 23. Non-English speaking. 24. Known cardiac condition causing or with potential to cause arrhythmia 25. Patients diagnosed with narrowing of the arteries (carotid atherosclerosis) 26. Patients who have had surgery to cut the Vagus nerve in the neck (cervical vagotomy) 27. Patients with clinically significant untreated hypertension, hypotension, bradycardia, or tachycardia.~28. Have a metallic device such as a stent, bone plate or bone screw implanted at or near their neck.~29. Are using another device at the same time (e.g., TENS Unit, muscle stimulator)

- Gender: ALL
- Minimum Age: 18 Years
- Maximum Age: 75 Years
- Healthy Volunteers: f

Study Arms:
- Non-Invasive VNS (Type: EXPERIMENTAL): Non-Invasive VNS will decrease inflammation in people with Crohn's disease leading to decrease in inflammatory markers and symptoms of disease.

Based on this trial design, predict the completion outcome and termination type (if applicable).
