  11. Clinical diagnosis of sepsis;
  12. History of ectopic pregnancy, pelvic inflammatory disease, or severe endometriosis;
  13. History of peritoneal or vaginal trauma;
  14. Co-morbid condition(s) that could limit the subject's ability to participate in the study or to comply with follow-up requirements, or that could impact the scientific integrity of the trial;

  20. Previously enrolled in the current series of 4 trials investigating the EES NOTES GEN1 Toolbox;
  21. Any contraindication listed in a study device Instructions for Use (IFU) document (if that device may be used in the study procedure); or
  22. Any condition which precludes compliance with the study (Investigator discretion).
